Computer restarts randomly?

[thomasd221]

Hi, my computer has started experiencing problems since i put a sapphire hd7770 ghz in it 2 days ago.

Basically, i can be on the computer, it will just restart, no BSOD, no warning, it's like something just gives up.

I know it's not overheating, i have a good CPU cooler and the graphics card is brand new.

I know the AMD Radeon drivers can be troublesome, i'm running the 12.11 Beta drivers, any problems with those?

The ram is also new, 3 weeks old.

It could be my network adapter a Belkin F5D7050 USB. I was having BSOD's with it, so i upgraded the driver, but it could still cause restarts?

if anyone can point me in the right direction, that would be good, also, hard drives are not fragmented and it's a reasonably clean install of windows 7.

?? Cheers!

what power supply are you using, and were you using a discrete gpu before?

I am using a FSP bluestorm ii 500w, should be good enough for a 7770.

Before i was using a 8600GT

Under load the 7770 is at 60 degrees, is that right?

Thanks!

You need to make sure your NVIDIA drivers are wiped, and yes the temps are fine

I uninstalled them, deleted it from program files and C: drive, is that wiped enough?

I think I may have fixed it, i installed auslogics boostspeed and ran some of the scans and defragged the hard drives, turns out they were both 11% fragmented!
