Black screen freezes randomly but pass test with Furmark and Prime95

Hi,

SPEC:
cpu:Core i5-2500K
mainboard:Gigabyte P67A-UD3-B3
ram:G.SKILL DDR3 4GB XL 1600(2GBx2)
WD Caviar Blue 1TB EALX 3Y
VGA:Gigabyte GTX 580 1536MB DDR5
PSU:Scythe GOURIKI-III 700W
Sync:Cooler Master 212 Plus

This just happen yesterday and never happen before. I haven't use my PC for about a week. So no change to drivers or windows system.

The PC is about 5 years old. It was fine until I used it yesterday. I play Football Manager for about 10 minutes then my screen goes black. the light at the monitor power up button starts to flicker. The keyboard and mouse LED is still on. PC is still running, fan is still spinning but I cant do anything. If I press the power button, it will shutdown immediately, I don't have to hold the button down.

I tried restart and play the game again. Same thing happened. I try Dota2, same thing happened. So I watch youtube instead, same thing happened again. There's no dump file written at all. So, I
used my phone to search for fix. I've learned about Prime95, Furmark, HWMonitor etc.

I ran Furmark for 15 minutes. My GPU max temp was 70C and PC didn't go to black screen

I ran Prime95 for about 5 hours, CPU Max temp was about 60C. PC ran fine as well.

Then, I launch Dota2 again. My PC goes to black screen in about 10 minutes. I'm not sure what's wrong with it at all. What am I missing and what else should I do?

Thanks!

  1. If you have all latest drivers (?) would i look at the psu first.Can you test with another one? maybe from a friend or ...
  2. they are not the latest drivers. I haven't update them for quite a while. I'll update it today if that would help. I'll ask my friend for a psu as well but wouldn't it fail during prime or furmark if it's a psu issue?

    Maybe if you run those individually no,but try them together and see what happens.A game uses both gpu and cpu,these programs only test one of the parts.
