BSOD and lag while gaming

I'm having one major and one minor problem with my computers in my cave right now. Here are their specs:

Computer #1
acer AM1640-E1550A
Intel(R) Pentium(R) Dual CPU E2200 @ 2.20GHz
2 gig of DDR2 RAM
Windows 7 Ultimate 32-bit
ATI Radeon HD 4600
300 gig SATA hard drive
450W power supply
Generic Omnitech plug & play screen

Computer #2
Intel(R) core i5-760 @ 2.80 GHz
4 gig of DDR3 RAM
Windows 7 Ultimate 64-bit
Geforce 8800 GT x2 (SLI)
500 gig SATA II hard drive
600W Cooler Master power supply
Calypso plug & play screen

Those two computers are plugged on two different extensions, which are connected to the same power outlet with the router and the modem.


Problem #1: (My first problem concerns uniquely computer #1)
While I play any video game on my PC, I get a BSOD. Here's the critical error (that I pasted from the event viewer)(Sorry if it's in french)

I re-installed Windows last week because I had exactly the same problem before. Also, I don't think those BSODs are random. When I install a fresh OS, I can usually game for about a dozen of hours non-stop. After that, I experience a really mad 30 sec duration lag spike that totally freezes my computer, creating a kind of sound repeat in the background. 5 minutes later, I usually get a BSOD and the computer restarts. I re-open my computer and I get to play for about 20 minutes before having another BSOD and if I don't use my computer for 2 days, I can usually play for 5 hours straight before the next BSOD. I have absolutely no problem with it when I don't game on it. The strangest thing is that if I restore my computer to the date I installed Windows, I can play several hours again. Here's the information dxdiag gives me:

Problem #2:

About 5 days ago, I had a athlon X2 3800+ instead of my computer #2 but the motherboard failed. When I tried opening the computer, the fan turned for 2 seconds then it dampened and nothing happened. I decided to change the whole computer by Computer #2 and it really rocks! When I play WoW on it, I usually cap the 60 fps anywhere I am in the game. Strangely, my brother had his anti-virus open while I was playing and my fps dropped incredibly.(20-30) I lowered the shadow details and the anisotropic level but it didn't even help. My FPS went back to normal exactly when the anti-virus finished.


I'm more concerned about problem #1 right now since I might be needing new hardware. Any help please?
 
Can you please attached minidumps with your next post?

You can find them in C:\windows\minidump. If you have multiple dump files simply zip them together.

What is make/model of PC 1's PSU ?
