I have a Computer with these specs below:

Intel Pentium Dual Core E5200
3GB Kingston DDR2 800mhz (2gb+1gb)
Palit GeForce 9400GT 512mb
AND A CRAPPY "ACROSS 500watts Power Supply" with only 14a on the +12vrail

I usually play GTA4 on that PC with an average of 36fps at 800x600. Then I upgraded my Processor from a Pentium Dual Core E5200 to a Core 2 Duo E7400 and Changed my video card from a 9400GT 512mb to a 9500GT 1gb. I put the Pentium Dual Core and the 9400GT in my other PC. As soon as I played GTA4 in my Core 2 Duo with a 9500GT PC, the graphics were distorted and ends with a BSOD saying that the drivers a reset... blah blah blah... I updated my drivers to the most recent which was 182.50 from but still the problem exists. So I tried installing another game. GTA San Andreas worked fine for about 30 secons then it was lagging and also ended up with a BSOD saying the same thing. What could possibly be the problem? Could it be my power supply not being able to supply the current neeed by the graphics card? I was just thinking though because the 9400GT and the 9500GT demands the same 18a minimum in the +12v rail and GTA4 runs fine with it before with the same power supply having only 14a on the rail. pls help me out. Could this be the processor? because I returned my 9500GT to the vendor and they replaced it but the problem is still there. Pls. help me. I am desperate to fix this.

My PC specs: (This is the PC I am refering to, the distorted graphics)

Intel Core 2 Duo E7400
ECS G31T-M7 (The same board)
3GB Kingston DDR2 800mhz (2gb+1gb)
Inno3D GeForce 9500GT 1Gb
AND THE SAME CRAPPY "ACROSS 500watts Power Supply" with only 14a on the +12vrail

More about : distorted graphics pls

Both of those games can be quite demanding and may be over stressing your video card.

You may also be overheating your entire system. You mentioned a slowdown or lag, which can be a symptom of an overheating processor.

Here are a few utilities that are very easy small downloads and do not try to take over your system:
Real Temp

You can use these to verify your system is configured correctly, and see if temps are getting too high while gaming.

And yes, regardless of whether it is the source of this problem, you should get a decent PSU.

Thanks Proximon for the links. Ive tried monitoring the temperature. Is it too high for my CPU to have average of 37 deg. celsius on idle?

No, but it's under load that you need to look at. Be sure to check both core temps.

If you can post screen shots of your CPU-Z tabs I'll make sure your settings are correct... I would rather not have to wade through the text wall the program generates though.

Also, completely remove all your video drivers and install a fresh one.
