Can you guys help me figure out whether or not this is a psu issue...

Hey all

Thanks for reading my thread,

Here's the setup:

CPU: Phenom II 720 x3
Mobo: MSI 790FX-GD70
Vid card: HIS Radeon HD 6950 2gb
4 Gigs of ram (can't remember brand/model)
Some HP dvd burner
3 1tb drives (seagate barracuda, wd caviar green mix)
1 2tb seagate barracuda drive
PSU: Corsair TX650
OS: Win 7 x64


Previously, I was running the exact same comp sans the 2tb drive and with a 4870 instead of the 6950. I bought a new, bigger case, popped in the new drive and switched the video cards.

Now, I didn't uninstall the video card drivers before removing the 4870 as I should have (I came across an "orphan" 6950 while exchanging the case and decided to take advantage of the opportunity and exchange vid cards while I was at it). Once I powered back on, I uninstalled AMD drivers and reinstalled them again. I'm running 12.3 cats.


Issue: while running games, computer hangs, and after a bit I'm thrown back to desktop, windows reports AMD driver has hung up.

I checked temps, vid card doesnt go over 75 degrees C. I don't believe that's terribly hot for the GPU, as I don't even hear the fan working hard while gaming.


I'm still planning on reformatting my OS partition this weekend in case I made a mess with the drivers, but I believe i should get psychologically ready for the possible fact that my psu might not be enough for this setup.

What do you guys think?

Is a 650 watt corsair PSU enough to power a 6950 + 4 hdd's (plus a bunch of cheap, low power case fans)?
Could this be a driver mess, or maybe I'm overheating somewhere else? (my rig is air cooled, and I'm somewhat afraid of how silent my new case is... I wonder if all the fans are doing their job)


Any extra info I should provide to better diagnose the problem?


Thanks!

PSU is fine and is not the problem. More than likely to be a video card or driver issue.

Could be the GPU overheating while 75C is up there but not crazy or just a driver issue. Make sure you have all the updates and latest versions of drivers. PSU is fine though you've got 53amps on the +12v rail which is more than enough to run a GPU and the HDDs.

Thanks guys. I'll reformat as soon as I have a chance and hopefully that'll fix me up.
