Hello everyone, and thank you for reading this:

I've built a computer out of individual pieces i bought around two months ago, and since then it randomly restarts.
I am a first time builder but I did everything very carefully and watching/reading a lot of guides while in the process. It is the second time i post the issue since the first time i did not get a lot of nor useful feedback.
The problem: The computer restarts at completely random times; i might be watching a youtube video, surfing the web, playing a game or just sitting without doing anything.
As for now, never restarted in the BIOS.
No bluescreen is shown (even though in the bluescreen view program i can usually see the crash there, written as a 00000x124 code issue.
It always restarts, it doesn't just turn off, it reboots completely to the part where i have to type my password.

-Computer hardware:

·Motherboard: Asus M5A78L-M USB3
·CPU: AMD FX 8350 Vishera Black Edition.
·Ram: 2x2gb set, 1x2gb stick. 1333 frequency.
·GPU: Sapphire AMD R9 290 4gb VRAM (first version that came out).
·PSU: Sentey 850w Solid Core Power 80 plus.
·HDD: Seagate Barracuda 1TB 7200rpm.
·NZXT Phantom 630 white.
·LG Dvd/cd writter/reader combo.

-Things i tried:

·Trying individual ram sticks in every motherboard slot (3 sticks, 4 slots, for a total of 12 tries).
·Monitoring tempertures (every piece of hardware running as cool as its suppoused to).
·Brought the PSU to the store to see if it was broken. They sent it to the manufacturer who tested it for a day showing no issues. So PSU completely ruled out of the equation.
·Removing the Graphics card along with its drivers to see if it was causing the issue.
·Disable BIOS functions as: Anti-surge, energy saving features, etc.
·The voltages readings in the BIOS seemed OK, but I don't know much about this.
·Flash the BIOS with the newest of the website.
·Set BIOS to default settings.
·Trying a different energy output of the house.
·Reformatting the computer/reinstalling the OS.
·Checking and rechecking that every hardware driver were updated to the latest.
·Trying out a different keyboard with a different mouse (somebody told me there could be an incompatibility with the motherboard).
·Probably some more stuff that im forgetting to mention.

Please note that i am quite desperate at this moment... I've spent 2 months trying to fix this issue. The computer costs around 1500 U$s in United States, but where i live is almost twice the cost, and wasn't even able to try it out yet T_T

Every individual feedback is immensly appreciated. Thank you so much for your help!

everything points to hardware being the culprit. i would start by downloading and running memtest.

http://www.memtest86.com/download.htm

the site has instructions for using this. here is a diagnostic tool for your hdd.

http://www.seagate.com/support/downloads/seatools/

also here is a site which has a pretty good tutorial on troubleshooting this one.

http://captaindbg.com/hardware-diagnostic/

he mentions also using prime 95 with a good temp monitor as this could be cpu related.you might even consider checking the cpu cooler.is it seated properly?have a look at the thermo paste ( while in there i would just clean and reapply).hope some of this helps.

Yes, everything points that way. I don't think memtest 86 will help as I already phisically tested all the ram memory. I also already tested the hdd with the seagate official tool. No problems found there. Used Prime 95 until test 8 with no problems (it restarted right after), I was monitoring the CPU temps while doing so (with CoreTemp) and tempertures were 57ºC at full load and for around 15 mints (before it restarted).
I will check the guide... though I don't feel like its going to help, read about 7 by now, they aren't that different, but fingers crossed.
About your last sentece... you know what? might do that, thought it couldn't be that if the tempertures were bad, but i could just resit the entire processor to see if it helps, its the only piece of hardware i didn't reseat by now.
Thank you for your feedback.

I don't know if you are still subscribed to this thread. Anyway, is it possible that reseating the CPU on the MoBo will help even when tempertures are right? If the thermal paste would have cought air or something woulnd't that mean directly a heating issue?
That aside, you had a badge on motherboards, do you have any insight in how to know if its the motherboard before i rma it? Last time I RMA'd something it took a month to come back...
Thank you for your help!

Has anyone suggested that an infection can cause this issue? Download Mbar http://downloads.malwarebytes.org/file/mbar/ and it will search for any rootkt (which can infect the bios to the point where flashing it won't even help) that might be the culprit. Saved my butt a few times.

if the temps didnt get above 57c its likely not a heating issue,but you may have bent some pins installing the cpu.me,id try reinstalling the cpu as well as the heatsink grease while im in there. to me it doesnt act like a motherboard issue but your pretty much running out of other options.

I will see if that helps gamesturbator, but i don't think its an infection, as everything is brand new, there was no time for me to infect it, lol.
Bent pins? I don't think so because i was so extremely careful, but i might, i would hate myself for it so much though :C

Hi

By searching online it does show that the error code you experience 00000x124 could possible be CPU.
Did you download a temp monitoring program such as CPUID HWMonitor? or Speedfan?, what temperatures is your CPU getting to?

Also with that program you read the bluscreen dumps? BlueScreenView? If so it should give you a list of all the shutdowns and ... see if there is a recurring problem on a specific address or a random everytime.

Recently I was convinced that my MotherBoard was at fault ... as I kept having bluescrees to everything... randomly and regardless to time! (I just do not like my board lol).
Anyhow I found out that my 2 x 4GB 1333MHz DDR3 RAM modules ... do not like the M/B anymore I replaced them with 2 other ones (2x2GB DDR3ones but 1600MHz). I was suprised that both of them failed.... and the same time they will work fine on other computers!!


Apparently maximum operating temperature for your CPU is 60C ... before bluescreens appear etc, and being a threat to it's own wellbeing lol.

As mentioned on my other post

"I had a case where I made a PC for friend of mine I had open budget at the time... so made him one with an ASRock FX990 Fatal1ty Professional Series and the AMD FX8120 3.1GHz x8 Black Edition. For the first 6 months the PC was aircooled with the stock AMD fan ... I thought it was fluescreening often... for my liking. I blamed down to the 16GB DDR3 RAM, so I lowered the RAM speed. The CPU temps would not go more than 46C .... so I could not relate it to over heating!
Anyway ... a couple of months later and after we installed watercooling (Kulho 920) , The temp would not go more than 38C and this under full load!
However the PC started bluescreening... and even started freezing on the boot screen sometimes where displaying the Fatal1ty Logo!
Soon found out that the CPU was faulty and it was playing up acting like over heating even when it was 32C ... the tollerance got smaller and smaller time by time.

I opened and RMA with AMD, sent the CPU, I had to be without a PC my self as I loaned my CPU (Phenom II 965 BE) to my friend while his CPU was replaced, the whole thing took about 1wk. Cannot fault AMD.
They sent a brand new CPU, installed it and since then he has no problems what so ever!

I must admit though it is difficult to pin point a problem to a CPU. Especially one that has never been overclocked in it's life!"

Actually the maximum operating temperture for my processor is 83ºC (according to AMD).
Yes, i downloaded a program to monitor my CPU tempertures (CPUTemp), and it never gets above 57ºC under full load. With BlueScreenView it says that most of my random reboots are 0x124 with very little exceptions.
So what should I do?

If you look at this thread regarding the temperatures, all suggested that a max 62C is for your CPU, on a non over clocked mode.
So 57C you're getting is well within in spec :).

Does your system reboot or shutdown even outside of windows??

Also the Bluescreenview will tell you the Bug Check Code and the Filename of the program caused the crash... or that was operating when the crash happened.

Do all the crashes show the same program over and over again?

No, it never shuts down outside of windows... Yet I don't belive its OS related since i have reformatted the PC twice already... The bug check code is 00000x124, and the program is almost always windows kernel related, which i don't know what it means... If you want me to i could turn it on and take a picture of blue screen view's reports so i can show you, though i don't know if that might help you resolve it at all

aldan, you have no idea how much i appreciate you coming back, reading the updates, and givng me feedback. Yet the thing is, I didn't just check the ram, for the problem to be the ram (that was running in my previously healthy system, as it is the only component that is not new) there would have to be 4 broken sticks, or 4 broken motherboard ram slots. Its so highly unlikely, that I have to check all other possibilities first. I tried to run memtest before though, but i did not have a virgin dvd at hand, so i went for the phisical way (I read somewhere that is possible to run memtest from a flash drive, but i tried and i dont know how, as the program says it has to be burnt in a cd/dvd).

It is not unlikely for a RAM module to get a dislike to a system...
I had my 2 x 4GB DDR3's stopped working properly on my machine rebooting etc and blue screening like mad. Crashing the web browser all the time.
Yet if I installed them on another machine worked fine.

I installed two totally different modules on my M/B and everything dissapeared, machine is working perfect, haven't had a blue screen for weeks, not even a program termination.

The code you post is kind or memory related. If that is RAM or Cache memory... not sure.
However I would say can you borrow a module from someone and test your PC for a while.

Word of advice while you test the new memory module do not have any of your 4 modules installed on there.

That was one of the first things I did; a friend of mine that has the same CPU and the same motherboard let me borrow one of his 4gb memory sticks (that worked perfectly on his pc) and we tried it in two different memory slots and the computer kept rebooting... After talking to a friend of mine that knows a lot about computers he said that it is likely that it is a motheboard issue, and told me to RMA it. So I will, maybe later today or early tomorrow, but i already uninstalled the components of the motherboard and packaged the motherboard back.
One big HUGE mistake i made happend when i took the heatsink out of the motherboard, the cpu was glued to the computer heatsink (the thermal compound was pretty cool, because my computer hardly ever gets over 20 mints of session and it did not warm up the last time i used it) so it came out of the motherboard socket along with the heatsink. I checked the pins of the cpu and every pin is in perfect condition, yet im still terrified, and the cpu is still glued to the heatsink, i will have to find a way to separate them... I read on the web that it can be done with a hairdrier to heat it up and make it less solid and a dental floss to actually separate them...

I will post here the results of my journey, that I will embrace tomorrow morning. Thank you guys for the replies!

Many might disagree ... but the way I separated the CPU's before from heatsinks was IPA spray, it does no damage to the cpu and it evaporates easily. Yet makes the cleaning of the cooling paste a treat.
Warming it up with a hairdryer prior sprays IPA is not a bad idea either.

Well i brought the motherboard and the CPU to diagnose to the place where i bought them... Now i regret bringing the cpu: the guy that takes care of the technical service was a bit careless when inspectionating the cpu (grabbing it from the back and from the pins instead of from the sides) and while he was doing so, I (seing such agressive inspection) told him that If he was searching for cpu bent pins, he would not find any. The guy said some seconds lates, showing me, that two were (when he showed me, i very carefully watched, and did not see any) and told me that if it was the cpu he was going to send it to amd and let them choose if the warranty would be voided or not. Now im scared, i did not see the pins bent at any time (i inspected the cpu very VERY carefully before bringing it) and im afraid he might just send them another cpu that they had broken there and instead of fixing anything they will just return me another broken cpu (thats not mine) instead... I dont think i would have any proof that that is not my CPU, so im frighten now, lol...
I hope they don't scam me, and just fix the motherboard...

Thank you for giving me hope... Now i'm a little more calm, and in the worst case, im assuming a loss of 400 U$s, which is a lot to me, but i can take it, as im selling my old pc for about that price. It's just causing me so much stress, i was suppoused to have been able to enjoy this computer from december, such a pain in the a**. I sent them a mail explaining the problem that i had so that they can attack it faster and give me the answer as fast as possible.
Thanks for reading so many boring posts aldan, it's appreciated.

So guys... Probably you are not following this anymore, lol, but i have some updates: The motherboard and CPU turned out to be fine, so what I did was removing the graphics card and using the Display driver sweep A.K.A. ''Driver sweep''. Since then it did not restart. I also tried the power supply in my old computer, which hardly consumes 400w, but it still worked just fine. Also i had already sent it for a RMA and it came back turned out to be fine.
As of now my main suspicion is that its the GPU. A freking bad GPU. So what i will do is go this saturday to the store i bought it and RMA it. It will last for atleast two weeks, and if its solved i will be back to post it.
I tried underclocking it up to 7.5%, and limiting its power consumption up to 20%, while keeping the computer running longer, did not solve it. So thats also a reason why i think its not the PSU.
Never really thought it could be it, seemed like a strong component in the build (costs almost half of the total worth of the tower), but i guess (and hope) this is it.
Will be back.
