Help !!! Game problems

[syborfical]

Help me please !

My hardware:

Mobo: Asus A8N-sli

Ram: 512 x 4 Geil DDR 400 2.5-6-3-3

Video Card: Leadtek PX6600 128mb (GT6600) PCI-e

Hard disks: Seagate Sata 8mb Cache
120GB
160GB
200GB
250 GB SATA2

Optical drives: LG 52x32x52
Poineer 109

Power supply: Antec True power 550W

Problem:

When playing Direct X games the computer will load and play then. Then after a while this is bit Random it will close the game. Drop back to the desktop.

Things I have tired:

I had all the hardware working fine in another A8N-sli.

One stick of ram 1 hard disk no optical drivers. Fresh format installed windows
Latest Drivers Direct X 9c etc. Crashers

Same with different drivers Crashers

Different Hard disk full format installed everything Crashers

Not to throw the PC against the wall because this is driving me insane.

Running Prime 95 over night CPU temp was 57 deg when I woke up

Running a CPU bench marking program over night cpu was 57Deg when I woke up

Ram Mem test 86 over night fine when I woke up. Tested Ram in my other machine same results
Ran 3d Mark 05 all night long was still running fine when I woke up. Video cards temps where normal.

All my hard disks and Ram work fine in my other machine!!!

I runs the net fine, but doesn?t want to run games?

Sometimes it takes ages to boot a lot longer than my old A8N-SLI?

Could it be the motherboard ?

Can't say I'm full of ideas. Might be worth having task manager running or something similar, try to catch what it is that makes the game quit? If it'll crash if you just leave it there in the game, you could see if anything suddenly behaves differently around the time it crashes.

If the games were, shall we say, free from the internet, it might be a virus that gets installed with it, I really don't know, as you seem to have eliminated most possibilities.

Try taking off a side panel and blowing a desk fan into the PC, if then it takes longer to crash, then it could well be a heat issue, but I don't honestly know.

Sorry I couldn't be of more use. It's a bump at least .

This is a little bit of a reach..but..I have seen it before. Try reducing your desktop display resolution to equal the resolution you are playing in the game.

Latest BIOS and chipset software installed? All service packs/updates installed? What are the CPU and RAM voltage set to?
