Pc was fine till now. The build is quite old, with gigabyte 880gm usb3 mb, 8gb ram and amd x4 955be processor.
This started yesterday night. It didn't beep on first attempt. I had to hold the power button to turn it off and restart. It worked.
2nd time I had to wait even more.
Now it seems pc wont boot, been waiting since 30 mins.
So, it's kinda random for it starting. Holding the power button to turn off the led and fans doesn't always work. I have to hard power off.
I detached RAM, fans, HDD etc, still the same problem, no beep and just the led lights. Please help asap, I urgently need to turn it on.
Thanks.
Ps: afaik, there was an led that would light up on the mobo, and now I can't find any when it's not turning on.
And everytime it booted with problems, I had to set bios to default after it asked me something.

Maybe your motherboard has gone kaput.. did you overclock your CPU?? what is the power supply (PSU) you are using??

maybe the processor itself got burnt up.. because even I got the same build (965) and I accidentally bent one pin of the CPU when cleaning and I faced similar issue of the PC not booting up.. since you say that its booting into bios.. the chances of your CPU fried is pretty much there.. also RAM.. try using one ram stick at a time to isolate the issue.. if its RAM, just RMA it or buy a new one..

The heat here is crazy I agree with that.. that's why I had to get a custom aftermarket cooler.. btw i'm from hyd, ap..

maybe the psu has died. List your build - every component make and model. And the OS

but faulty cpu would randomly act? Also I tried removing , one and even both the RAMs and no beeps.

I didn't overclock anything. Could a dying psu act like that?
The psu is of 550w and it's a local brand, not the cheapest, but decently cheap. Also I edited my post...the bios asked me about loading settings to default or previous good.
I did previous good and then tried default too.
So all these symptoms still say it's psu?
The heat in my city has been high lately. I'm in Mumbai, India.
Edit: another observation. The power button on cpu responds only if pressed immediately after boot, and reboot button doesn't seem to work.

okay, I'll wait for others.
Btw, I see Turbo 3D card or whatever it is, maybe my ati radeon4250, it's loose, I'm able to pull it a bit up cause of spring type screws. Does not look detachable but can that be the reason? If I will to verify if it's the reason, how can I?

We really need to know the make and model of the psu to be able to judge whether its any good.

Can you borrow another psu and try it?

It's: Power Focus-550W.

And it's sure that my PC starts after I turn it on, let the LED & fans be on for a good time and then restart.

Also after it started after waiting for more than an hour, I was testing and, 80% of Windows' restart commands led me to CMOS checksum error page where I used to load defaults.
And I can't get a psu for testing at this moment.

Power Focus - another not known brand. I get a lot of problems reported with PCs with cheap non certified power supplies. If you want to give your pc the best chance of a healthy life, please get a really good power supply. Preferably something mad by Seasonic - either under their own brand or XFX or some of Corsair and Antec eg Antec HCG 520M

Just to check, if and when the pc starts can you check the voltages from the power supply using HWInfo (download it for free). I need measurements of the 12v, 5v and 3.3v lines showing for each their min and max values.

This session was when I had to keep the machine powered on for a while and then reboot so it'd start. Though, this was taken hours after the boot.

And 2nd, I just restarted and took the screen:

yes.. like I said before and i7baby says.. you gotta try upgrading your PSU.. but as long as it's working.. don't worry.. but avoid heavy applications..

Best solution

April 26, 2014 4:14:43 PM

Well it's NOT WORKING. The 12V voltages are too high. Replace the PSU with a good brand.

If you list your build we might be able to provide some advice on what psu to get.

April 26, 2014 5:41:35 PM

Alright, so PSU it is?

Mobo: Gigabyte 880GM USB3
RAM: 2 * 4 GB DDR3 by Strontium - 1333Mhz
Proc: AMD x4 955BE 3.2 GHz
HDD - WD Blue WD10EZEX 1 TB
and a normal DVD r/w by LG.

Is that all? I do plan to add an external graphic card in near future, but that won't be a heavy one, I need decent NFS games on mid-high settings, that is it.
Thanks.

OK so at the moment you have a minimum power system. 300W should be enough. But get a good brand eg Seasonic - under their own name or XFX or some of Corsair or Antec PSUs. It needs to be 80plus certified - bronze at least.

April 28, 2014 6:48:39 AM

Okay. Will 350w be enough if I add a mid-range gfx card?
Also, could you suggest the best one for me? I'm not willing to spend more now.
if you're not from India, here is a link that would give you an idea about the rates and products available:

You will not get anything of quality at such a low price mate.. coolermaster is so-so.. suggest you have a budget of atleast 5000 INR... Then you will get a decent PSU. PSU is something that is very important. it supplies power to your whole system!! never neglect that bit as it has the potential to fry/destroy your whole pc (or burn your house in flames) if it is not of a good quality. Like I said before, do not apply much stress on your system.

Take that but do not expect wonders or quality. and try not to use heavy applications like Photoshop/games etc...

I'd call a mid-range card a GTX760 which needs 500W. But you might call a GT640 mid-range which only needs 350W

Before we go further, can you be sure that a new psu would fix the problem? It'll be difficult for me to test stuff, so asking.
Yup, GT640 would be something in my budget.
And I can concentrate on current system and buy for this build; cause I can use the psu on other system in future.
So tell me if 350w one would not limit my usage and stop me from gaming.

You might have other problems as well as the psu. But your psu does need replacing - with a GOOD one. When you get one and install it, we can then see if there is anything else wrong.

You need to borrow a pc for your exams/study till you fix your one.

Oh that stings... after reading your thread, it was quite plausible to be a psu problem.

Bad psu can also affect and damge other components, well since you have a new psu, can you post its model and specifics.

This may sound very bad... but what you can do is to try and reseat (not reset) your cpu chip, but you will need a thermal compound and a can of compressed air.

The problem can now be narrowed down to your cpu chip and the motherboard, but lets just assume first that nothing is broken, just a DIY dust removal on your cpu socket.

After I faced this problem, I had done cleaning of cpu chip, applied the thermal paste too.
I can redo if required.

Remove all the ram and video card, if theres something on other pci-e slots, remove them aswell.

Start up your system, if you have a motherboard speaker it should produce a beep code. Or at least power on the mobo.

May 8, 2014 4:01:10 AM

no beep, just the fans and power light near power button.

if in case you missed, the computer does start randomly. though, i haven't tried multiple times like I did on old psu.

If your certain you have a motherboard speaker (" the cylinder magnet thing"), then it should have produced a beep code alerting you that theres no RAM stick attached, but your mobo is still receiving power because the fans attached to the mobo is on.

Thus, next step, but this is looking bleak for the mobo and cpu.

From the power supply theres a 24 pin motherboard lead and a 8 pin ("that can be split into 2x4 pin") eps connector.

If your motherboard uses the EPS connector, remove that for now.

Then start it again.

detached the rose 2* 4 cables. same thing. I did that with and without RAM, both.
Do specify if these are to be attached back if testing something.
and thank you very much, this is live support. :p

May 8, 2014 4:49:50 AM

Ok, if the EPS lead is disconnected, then supposedly you powered on your system. A beep code should be there and/or the fans connected to the motherboard will spin indicating theres power to the board, then stop for a second then spin again indicating a power cycle.

That was to test if the mobo can detect that there was no CPU attached.

I don't get you. I have started the system without eps and the over and fan are ON,just like it was with eps. What does it mean?

May 8, 2014 5:10:06 AM

IMPORTANT!
New observation!
whenever my older psu started my machine, it made more fan sound compared to the sound when only led and fan were on.

I used this new and I got big sound even when system wasn't starting. I detached eps and tried 3 times, once without RAM and twice with. The 3rd without eps killed that loud sound and now,with eps there is no sound again. probably that's no sound of psu fan.

edit: it's coming again when I attached everything and tried.

Above mentioned situations had fans running. Just it was the sound.

Haaaa....

I cant be 100% sure but based on your replies.

you basically just succesfully diagnosed that your motherboard is faulty.

What i let you did was already risky, any further and you might damage everything or worst get electricuted. So we will leave at that.

I know its frustrating, but i can already see that we are having troubles communicating, which is not good.

But for the sake of trying... re-assemble your computer and hope it boots up.
