Help Heavy Gaming= PC RESTART

[has22fas]

Hi,
Ive been having a probelm lately with intensive games such as gears of war and terminator ever since i installed my new motherboard it has given me hassle. Whenever i play them after 5-10 minutes of play my pc will shutdown then 2 seconds later restart and POST. My Pc does not restart when i play Team Fortress 2 as i have played it for 2 hours. My Temps are

37C idle
49C Load

Intel Pentium D 940 3.2Ghz ~3.6Ghz Overclocked
2GB 800MHZ RAM
300GB western digital HDD
Nvidia Geforce 8800GS
620W power supply.
ASUS P5N73-AM

Artic Cooler freezer 7 pro FAN
HDD FAN
Case fan

Thanks peeps.

You should reset your overclock back to the stock setting of 3.2ghz, retest your gaming again. If they don't crash then your overclock is unstable.

If they still crash, then I would looking into getting the newest Nvidia drivers for your video card.

stock clock 3.2Ghz runs fine i dont know why is unstable. I think GIGABYTE is better than ASUS i had gigabyte GA-73VM with 610I chipset and asus with 610i chipset gigabyte oc to 3.94Ghz asus 3.6Ghz unstable and some random voltage controls like 150mv bs, I thought asus was good 2

Well a different board would require a slightly different overclock. Have you tried to stablize the 3.6ghz overclock?

Increased the NB voltage? Or maybe increase the vcore even more?

Try your RAM voltage and timings. I had the same thing happen (would play Bioshock and it would restart but light gaming wouldn't do it) when I first built my current machine. The mobo set the RAM voltage to low and the timings to high.

Hopefully that will help.

You need to clock back the ram on the Asus board, then increase NB voltage and CPU voltage to get stable CPU clock, then increase ram speed and timings in very small steps testing each change for stability, time consuming but necessary to find the stable overclock, If you have had the chip stable beyond 3.6 then it will do it on this board, just remeber that your memory and NB will also overclock, also how cool does the NB run and what quality PSU do you have? Are you also overclocking the 8800gs and have you run Prime 95 to see if it crashes when cpu 100% outside of gaming at 3.6ghz overclock?

hmmm thanks for the replys guys i dont think i have NB voltage im limited to over voltage control v1.35 and +50mv +100mv +150mv unlinked and linked ram and cpu FSB im not overclocking the 8800GS
