weird problem after changing my PSU!

apolloe11even · Feb 15, 2015

hi forum . i have changed my power supply because my ex power supply involved in the problem. and it's spec was 1035 Watt (1000 Watt Real) model GP1035B Green . with that (before it crash down)
my system was boot up correctly after i hit the Power On button on top of my chassis.
... since a few days ago that i've bought a new PSU with this spec : Green 1000 Watt (Real) OC edition model GP1000B GOLD (80 plus Gold) . no the problem is , every time i want to turn on my PC , first it doesn't boot up but it's powered on and all hardware are in correct position and nothing's weird . just actually do nothing .until i push 2 or 3 times Reset button or Power button from my chassis and then after a while when it re-started again everything goes well and system will boot up perfectly .
any help would be greatly appreciate to solve my problem . Thanks

System Specs:
OS - Win 8.1 Enterprise x64
CPU - i7 930
Video - GTX480
Mobo - Asus P6X58D Premium x58 chip
RAM - 6gb Corsair XMP 3

I would double check all of your connections, and make sure that you did not knock anything loose.

Cristi72 · Feb 15, 2015

Hello,

Take out the GTX480 and verify its PCI-e connector.
If all connections are OK, it seems your motherboard is living its last moments (damaged by the old PSU or some capacitors gone bad).

Thanks for the tips.
from your words i have to take a look to check them . and you've put me into a lil stress

which part of mobo did you exact mean? CPU connectors GPU? or all of connectors and cables that go out from my psu ?

Whtwolf · Feb 15, 2015

apolloe11even :

You need to check all of the PSU connections, and then all of the other connections in your computer. No stress, just take your time and start at the bottom of you case, and work your way up to the top and take as many breaks as you need. Make sure to ground yourself on the case, or use a anti-static wrist strap while poking around in there!

Whtwolf :

ok i'll take a look thanks.
and what if connectors from ex psu are a little different with new one ? is it a problem matter? from my ex psu the connectors cables had came out of the power supply . in the new one they are attached to the outside .

With the modular connections, do make sure that you have the correct voltage lines connected as required by your hardware.

It causes damage to the system or not? this abnormal event may causes the hardware damage? or the problem is not serious ?

apolloe11even · Feb 16, 2015

ok fellas . i double checked all of the connectors and cables and also on the board . no issues were found.
i'm totally confused ! why it should be like this? plz can you give me a vision of true connection between power cables and board? they are seated at the right position right now . should not be a problem!

i have a blue and red and black power supply cables . 1x8pin (red) is connected to the CPU connection . 1x8pin (blue) is connected to the PCI-E connection (both of the other side (1x8pin & 1x6pin) are connected to the GTX480) .
3x6pin (black) are connected to SATA ..
am i miss with something ?
Thanks for responding..

Whtwolf · Feb 16, 2015

Let us go back to the beginning; what happened when your 1st power supply have some "issues".

What did that involve?

apolloe11even · Feb 16, 2015

Whtwolf :

here it is.. , as always it work was continued until suddenly out! and after a few hours it back again . and out again! these problem continued for at last 2 or 3 days and then it officially never powered on again . the red\green(reset\power button) LED indicator (in the mobo) turned off and even if i was disconnect and reconnect the plug , nothing happened .
but randomly sometimes it was back again and when i was in the middle of something on my computer it happened again and powers out!
so i had to make a decision and sent my PSU to representation for warranty laws and for 3 time of repeat this story (that each time this out an in power event happened to me) they return this new model for me and jesus know .. it makes me happy

but now this problem that i mentioned at the first of topic has occurred .

apolloe11even · Feb 16, 2015

could it be related to BIOS ?because i was switching power supply? update or..?

Whtwolf · Feb 16, 2015

apolloe11even :

It would not have anything to do with the BIOS, and was wondering if your MOBO green lights were coming back on?

I think you should try this. Unplug everything except for your C:drive, 24 pin MOBO connection, CPU power 8 pin, and the heatsink fan. If you have onboard graphics, also take out the graphics card.

Then see if it will boot.

I am starting to think that in the death throws of your old PSU it might have sent out some voltage spikes and possibly fried something on your MOBO, or one of the other components.

Cristi72 · Feb 16, 2015

I am thinking your motherboard is at fault here (because of the old PSU? you cannot find out unless testing the old PSU in a laboratory).

Try this: power ON and, even if it's not booting, let the system running for about 5-10 minutes, then press the RESET button of your case (press it only once; you have done that, but right from the beginning, and I guess you frantically pushed the RESET button until the system booted). If the system boots normally, it means some capacitors from the mobo are worn out and it's time to an upgrade.

Also: doing a software restart (after a succesfully boot, from Windows), the system reboots normally or still stalls booting until the RESET is pressed? If it fails to boot again, try to clear the CMOS (resetting the BIOS, according to the manual) and upgrade the BIOS, even if you have the latest version installed.

apolloe11even · Feb 16, 2015

Cristi72 :

ok cristi72. will give it a try. Thanks
and Thanks to you Whtwolf.
i'll be back in next few hours and tell you the result..

apolloe11even · Feb 17, 2015

ok i'm back . i did whatever you said Cristi. first of all i powered on my PC and it's not booted again like before as i said. i let it work in this situation for at least 5 or 10 mnts and nothing happened . i pushed Reset button just 1 time(as you said) . then nothing happened again.(just hardware system sound and fans sound (noises) appeared a little have had sound drop because system Resets But still there was no sign of a boot )
so i pushed Reset button one more time , and in this case , system turns off for a while and back again and this is a sign that always makes me happy (as long as this PSU problems started for me

) . then all hardware and devices that connected onto my PC will turning On and system health beep is just have a beep that representing the system's OK. and Windows will boot up it seems that there's never a problem

.
i should add that ; after one fine working my PC and booting up with no issues, then my PC works fine and if i restarting from Windows or even with Reset button many times , there will be no problem , system will works all good. . even sometimes if i have had turning off (shutting down) my PC and turn it on again there's no problem.interesting. isn't it?

all of my problem is that most times when i want to Power ON for the first time my PC

so let me point to the Hibernate or programs which have a configuration for sleep timing or power managing(like auto shut down or power on or hibernate) . is there a problem in this regard ? (but i never had problem in this case before)
ok with this interpretation , now what suggestions do you have for me? and plz Cristi72 explain more about BIOS and with this things that i said , do i need to clear my CMOS (BIOS resetting and upgrade again) ?

Cristi72 · Feb 17, 2015

apolloe11even :

You could try that, as in this point you got nothing to lose, just be sure to follow to the letter the BIOS reset instruction from the motherboard's manual (especially unplugging the PSU from mains).

From my experience, such behaviour is a result of a failing motherboard: some capacitors of the motherboard don't have their nominal value anymore (the contained insulator + electrolyte degrades over time). Main causes: overheating (CPU / RAM / chipset / PCI-e x16 slot area), bad PSU quality (high ripple on DC rails) or low-quality capacitors (less likely, being a top-quality motherboard, even if it's a bit old).
The most interesting part is that such motherboard can work perfectly prolonged periods of time, but refuses to boot if the system is not powered up for a few days (or even hours, in "terminal" cases).
It can be fixed? Yes, by replacing ALL electrolytical capacitors from the said areas with new ones, but such endeavour is not always successful...

apolloe11even · Feb 17, 2015

Cristi72 :

new results and experience :
i decided to have had some tests again so i told by myself let's check the computer when it's powered off recently and i did uninterrupted turn it back ON again. it worked

i tried several times to power On and power Off (shutting down from windows) and it worked! so i get that when my machine is powered off for half an hour or maybe several hours then it should be handle this problem which i mentioned before.(and This test was a huge leap in my opinion

)
ok , let's get to the point from you and something more about my follow up..
look pal my hardware is not useless article or low quality ,It is true that the case of the 5-year career but it's article was the best at it's kind.especially my MOBO. and to ensure and ease my mind so i have shared the problem with a hardware expert repairman and he said usually this symptoms refer to the RAM . so i'm confused now to believe what exactly is the problem .
pluralization :
1- i'm thinking maybe it refers to my new and fresh PSU , maybe it has a new system delay /interrupt or maybe optional setting that can help through this.
2- maybe the problem is related to the cables (i'm not sure because i double checked the cables and all connections before)
3- if problem is related to the Capacitors as you said , so in this case Capacitors are usually swollen. but there is no sign of this condition , i also double checked Capacitors for assurance.
4- especially this PSU is the best kind of high power supplies and it's new . no sign of ripple / noise/ or any suspicious signs of its internal hardware.
5- so we can say , no MOBO suspicious , no PSU suspicious , no Graphics suspicious , anything but only RAM

at this point we can say maybe problem is refers to the RAM modules . because i haven't test it yet and i hope it is nothing to worry .
6- according to recent test , we can assuming there should be a common setting or case that helping us through this. because if there was a problem with any kind of hardware then why when i test it repeatedly ON\OFF uninterrupted there was no sign of a problem?
and one more thing that i forgot my friend , there is no sign or overheating of any kind of my hardware too.i'm always aware about this.

Cristi72 · Feb 18, 2015

apolloe11even :

Please don't get offensive with me, because you don't have any reasons to do so (or I am too sensitive

? sorry about that). Your motherboard exceeded its warranty period and even the normal usage period, which is 5 years, so you and ASUS should be happy (especially if you were one of the early adopters of the i7, in the fall of 2009). Also, it was not the best SK1366 from ASUS (Rampage or Sabertooth comes to mind). Even the mightiest have fallen, and there are no failproof components.

1 - If the new PSU is in good working condition, there are no reasons the system will not work as it should; I didn't find any legit reviews for GB1000B GOLD, but the older one was reviewed and its quality was good; of course, that didn't factored in the reliability, and 5 years means an awful long time for a PSU;
2 - the plugs can be easily fitted in one way only; it will necessitate hard work and strong will to fit them in the wrong way;
3 - your motherboard employs only dry-electrolyte capacitors, which gives no visual indication if failing. In the case of failure of such capacitor, you will see at best only a faint trace of electrolyte at the bottom of the capacitor or a specific odour, so you must desolder at least one of the capacitors and check it, both visually and by measuring it with a capacimeter;
4 - if a PSU has high ripple voltage, it remains the motherboard's job to filter the voltage, and that leads to premature capacitor wear (higher charging/discharging currents). Only a specialized lab can properly test the PSU, that's why a PSU review is useful. If you have an oscilloscope, you could observe the ripple at full load;
5 - try to use another RAM set, but I doubt it will change anything (unless you took out the DIMMs or the CPU at the time you changed the PSU); if the system starts flawlessly with only one DIMM, but fails to start with 2 or 3 DIMMs, the problem is again the motherboard (capacitors from the RAM or/and CPU VRM);
6 - I already shared my experience about this, and the resolution is either changing the capacitors, or changing the motherboard altogether.

If you don't mind, please share with us: how can you observe overheated areas on a black PCB?

apolloe11even · Feb 19, 2015

Hello

no i don't . it's OK my friend i am here to being help and learn knowledge .
First, I'll give the last word (PCB) , i didn't mean that.. (PCB) what i mentioned for, CPU /RAM/chipset/ and areas like these, by using the hardware's monitoring software.. which is monitors heat level and temperature.
unfortunately , from that time i hadn't enough moneys to buy Rampage or Sabertooth i know these are awesome editions of ASUS MOBO !
1- you're right.
2-checked.
3-i thing you're right and i should do something about it.
4-unfortunately i have not any kind of Electronic tools and also my knowledge is poor about this item

5-in this case i think i did something like what are you saying, when i tried to disassemble the PSU form my tower atx i took out the DIMMs i'm not sure about it but i only know i took out some part of my rig that time except CPU. but where do i know the problem may not came from the DIMMs?i mean some of Corsair modules RAM maybe corrupted . and problem not comes from capacitors or MOBO?
6-Thanks for your advise my friend i appreciate that.
and excuse me if don't mind please explain more about PCB. did you mean Printed Circuit Board?

Cristi72 · Feb 19, 2015

apolloe11even :

Yes, that's the definition of the PCB, and it means the support on which all components are mounted, the backbone of the motherboard. If the motherboard has a black PCB, the overheated areas (which are brown or dark red) are not visible. No motherboard has enough temperature sensors to check all areas, so there is always a possibility for much hotter spots to exists and to not be monitorized by the sensors (especially the VRM area, which employs lots of power FETs).

Try to test the DIMMs/CPU in another working system, it's the best way; it is highly unlikely all 3 DIMMs got damaged though, that's why the motherboard could be defective (a motherboard can still start with damaged capacitors, but not at full load, so it should start with only one DIMM and fails to start with more DIMMs). For the CPU part it's more difficult, as the SK1366 is not a widespread platform (workstations and power users mainly) and it will be harder to test; try to re-seat the CPU and check the pins from the CPU socket (be very careful, try not to force anything or drop the CPU onto the socket).

It could be also the GPU; GTX480 is known to have a good appetite for power (in excess of 250W for the GPU only, some models even breaking the 300W), which means high temperatures for the card's PCB and the graphics chip, running at over 80C. Try to use another GPU, or at least move the GTX480 to the second PCI-e x16 slot, see if it changes anything.

Thanks dear Cristi

nice post and information. i'll give it a try . i chose your post as "Solved" because of your good behavior and good information . my problem probably not going to be solve but i appreciate your responding and follow up. your 2/3 last posts are full of helpful contents , so i'm thinking outside this range will not be my problem. but if more question arise , i will come back to you.The rest of the story on my own hardware to actually do a test to see whether the outcome will be?
Thanks Regards.

OMG! it's unbelievable

i had to come sooner, but i had no chance i was busy..
i changed slots of PCI-E for my GTX480 and also i had a Booting test for DIMMs . my MOBO have a great ability called memOK! i optimized my DIMMs by testing them under the memOK as one DIMM per slot and seated them together and test it again. fortunately it worked!

Hell Yeah!
i dunno how to thank you dear Cristi72 i really really appreciate your hard work and follow up . my machine keeps boot up perfectly without any problem! i dunno whether or not they're relevant to this, but i had a clear and fresh OS installation on an SSD . actually i completely traveled from my HDD to an SSD (i know the problem was relevant before OS boot up but ok then..

) . so i told myself to share with you last result.
Thanks again .wow it's awesome

weird problem after changing my PSU!
