Hi guys,

Was just booting up a game (DayZ), and my graphics card fan spun up really really fast and the picture died. I hard reset and couldn't get a picture, but could hear the windows boot up sound through headphones. I reseated the graphics card, but after that the GPU fan just spins up really fast, still no picture and no longer hearing a boot up sound. Specs below.

Asus M4A79XTD EVO
Phenom II X2 555 black edition, unlocked to quad core and overclocked.
XFX HD 6850 black edition

This is a dated build now and been working fine for years.

Any help appreciated.
 
Unfortunately no spare PC to test the GPU in, but a friend at work is bringing in a GPU tomorrow so I can try that.

Will try clearing the CMOS, thanks for the advice and I'll keep you updated.
 
Guys, clearing the cmos seems to of done the trick! Huge thanks for that Wazza.

Now, more importantly, what could have caused this? I haven't had a chance to play games for an extended period yet, I'm worried that something is on its way out to cause this?

Thanks again!


EDIT: typical, the second I click post I does it again. Any ideas what could be causing this?

its unstable overclock if its crashing

esp your pc memory voltage or cpu northbridge voltage (not sure what its labelled as on amd)

can also be graphic card memory,test by downclocking it 200mhz and see if it still crashes
 
Hi Wazza,

Not sure if you saw my edit above, but shortly after posting that thread exact same thing happened. Black screen, GPU fan spinning 100%. Hard reset did nothing except cause the GPU fan to spin 100%.

Pulled the CMOS again and its currently running again, so there isn't any OCing at all on CPU, except I unlocked it to quad core which is what I did when I built it and has been fine for 3 years. No overclocking on the graphics card, or memory. Any ideas?
 
idk

did you see my post above? even stock clocks gpu or cpu can be unstable

it could be power supply or memory voltage

your not running an ssd are you? if so what make/model?
 
Humm, I just can't see why stock clocks would suddenly cause a problem after 3 years. When you say memory voltage, I have never touched them so can I rule this out?

I do have a gut feeling its the PSU.. I will try test with a spare one.

Thanks again.
 
it can degrade over time or just become faulty,thats with any component

random shut offs can be memory related or psu related and black screens with the gpu fan running full speed can be gpu issue

you have to go through each thing until you solve it,you can try with just one ram stick installed and see if its any better or try and borrow a spare psu and test with that

Click to expand...

Borrowing a spare GPU and PSU tomorrow so will report back. Thanks for your advice so far, appreciate it.
 
Little update, managed to play all night fine last night with stock speeds on my CPU, so I think the problem resides with the overclock on my CPU. What I don't get is, the overclock has been stable for 3 years, would could cause it to suddenly be unstable?

TIM degradation?
 
don't know could be anything,^^ temps or memory voltage not right or psu

try overclocking a little at a time in small steps till it becomes unstable,try and reach what you had before
 
Could it be the cores? The chip was essentially binned as a dual core and you've unlocked the 2 extra cores. Although it ran stable for 3 years maybe one of the cores failed tests during production so they locked the 2 defective cores? That's just a wild stab in the dark though.
 
Well, yes its a dual core, but unlocked it to a quad and OCed it to 3.6ghz for 3 years as I mentioned. I'm going to give it another good run tonight and if it remains stable on stock, then I will slowly OC it again until it happens again, and I'll check temp.

If it appears to be a temp problem I'll reapply the TIM, if not, I guess its just getting on a bit now. Maybe time for an upgrade!
