PC crashes under GPU load

Bramill · 28 Jan 2014 at 12:09

Hi, my pc has been freezing then eventually rebooting after about a minute of BF4 and using the evga stress test. I'm running a gtx 780 with a I5 2500k on a corsair TX 750w psu. I'm assuming my psu needs replacing. I'm thinking of getting a 650w modular seasonic, will this be ample?

I'm not really too knowledgeable on this subject...but I was getting the odd freeze here and there on BF4 a short while back....updated my Graphics driver ..and it seemed to fix the issue

I'm getting crashes consistently every time my gpu is under load, I have the latest drivers too. I've played 20 hours with the card on Windows 7, since upgrading to Windows 8.1 I've had problems, I'm hoping it's the psu as I've had enough of formatting this week.

Do you not have another PSU you can connect up and try

Unfortunately not, and I'm not keen to test it with a multimeter. I'm just gonna buy a new psu and hope for the best

What res are you gaming at ?

1080p the card is stable at 79 celcius when it crashes and no overclock. I've tested the cpu with prime95 and there was no crash and the temps where 50 celcius.

Run mem test on your ram to rule them out, how old is your psu ?

My PSU is about 30 months old, I'll try running memtest when I get home thanks
