Low FPS two different cards

Ive recently started having problems with ridiculously low FPS in all games and benchmark software.

My System

Core i7 950
Asus P6X58D
Sapphire ATI Radeon HD 5770
Crucial RealSSD C300 64GB
Samsung SpinPoint F3 1TB
Patriot Viper 2 Sector 7 6GB 1600MHz
450w Hyper PSU
Windows 7

I'd not benchmark my gfx before hand, but I could run all my games (Pro Evo, COH, NBA 2k11, DOW3) on max settings and it ran smooth.

Then all of a sudden, the framerate dropped an all games to unplayable levels plus there was some tearing in certain games. Also my screen would flicker when minimise/maximise browsers when playing video. (Running 2 monitors)

I downloaded a gfx benchmark software (cant remember what it was called, sorry) and it was telling me that it was running at 1fps! I could get it to 15fps when setting the resolution to 800 x 600.

I tried updating the ATI drivers and the problem was the same. And had a mess around with the settings within the Control Centre.

I tried putting my older card in (GTX8800) and the problem was the same.

Does this sound like a Windows problem or a hardware problem, possibly bad PCI slot (I did try it in both available slots and although one did give me slightly better results in the benchmark maybe 5/6 FPS on full resolution it still wasnt right.)?

450w PSU enough to run the 5770?

I'd rather not reinstall windows if i can get away with it.

Any ideas? Any help would be greatly appreciated.
 
How full are your hard drives? Have you run HDTune on them to check them?

Sounds like either full disc, disc error or PSU problem to me. (Given that you've already ruled out driver and GPU).
 
The SSD which has the OS on plus a couple of others, has 20gb free of 64gb. And I have a 1TB storage drive which has hardly been dented.

I might have a look at getting a new PSU.
 
most definitely it your psu causing the problem i would suggest changing it to either a 750w or 850w minimal. another thing to take in is currently you are most probably taxing your psu beyond it safe limits so it could be at risk of failing on you, but the thing is if it fail their one of two ways it will go 1) psu will simply stop won't power up 2)psu blows up (a. goes bang make a small explosion cauing damage to multi components in pc b. short circuit causing electrical damage to one or more components)
