Mysteriously slowing 275 GTX

Hello All,

I'm stuck with what's wrong with my stepson's PC. I built it for him a few years ago, and it was a low cost system since the games he played were not graphically demanding. He has since upgraded the video. Here are his current specs:

Pentium D 820 Dual Core
Gigabyte GA-945PL-S3
2GB DDR2
1k watt PSU
Hitachi 7200RPM HDD, 1TB
EVGA (I think) 275 GTX
Win 7 Pro x64

So, right off the bat, I know this isn't what you'd call a cutting edge system. However, since he spent 90% of his time playing Counter Strike Source and WoW, it seemed more then adequate.. and was. Until recently.

About a month ago, he said he was having slowdowns in WoW on raids. I don't know much about WoW since I don't play it but told him to turn down some settings. It still lags behind quite a bit. Now, even games that worked fine previously are lagging badly. Counter-Strike Source was freezing up today.

Everything looks fine to me. It's a pretty fresh windows install, there is no spywware that I can detect, and he doesn't have excessive processes running. His DX is up to date, as are the Nvidia drivers.

Any ideas at what I should be looking at?

Thanks
 
Maybe you could download GPU-Z, and check the temp sensors on the card as you run a game

That would be my first suggestion, to see if the temps are getting too hot for some reason.
 
OK, thanks for the advice. I ran GPU-Z and then played a few games. I noted L4D2 was completely unplayable - I'd guess about 10-15FPS, at best.

Temps seem normal to me. There are two GPU readings - one went from 41 to 46 degrees C, the other went from 49 to 53 degrees C. For comparison, my 470GTX is idling at 77 degrees C and went to 84c at load (AvP2) so it doesn't seem to be a heat issue.

The fan never went about 40% (1460ish RPM).

PhysX was on, and we turned it off. There was a barely perceptible improvement, probably none at all.
 
Ok, so we know it's most likely not due to heat because 53 C is very cool.

What if you put the 470GTX in the computer and test it out?
 
Are you absolutely certain he didn't get any viruses or change settings that could cause that?

Check nVidia settings for any sort of power saving mode etc.
