Odd problem when playing CoD4 and CSS

list your system specs, operating system, any software you are running in teh background (otherwise we can do nothing...  ) although interestingly, COD4 gave me issues as well, until that point, i had thought that my graphics overclock was stable, but getting rid of it sorted my issue out.

Nothing is overclocked as of now
3.0ghz dual core processor
nvidia 8800gt vid card
p5n-e mobo
2gigs of ddr2 800
windows XP is my OS
mostly i run like AIM and xfire in the backround, maybe a mozilla or 2

see i dont think it would be a hardware issue because other games run flawlessly, i get 60+ fps in bioshock and 40+ in crysis on high...

i used my mobo driver discs that came with, and my vid driver is up to date

Are you running FRAPS at the same time? I was having constant crashing when running FRAPS (older version) with some newer games. Download the latest version if you are.

ill completely uninstall it and see what happens, was the crashing your whole PC or just the game? cause my computer completely restarts

The game would lock up, I could still hear the sound but I always had to do a hard restart. Once I installed the new FRAPS, all of the issues went away.

well it just freezes for like 1 second, makes some odd noise, flashes BSOD, then reboots

tried it once again, it ran fine for about 3-5 minutes and then did the same thing - this time i exited out of all background programs.

I Suppose if you are really desperate you could try reformatting....

*nod* thats the next step i just gotta wait for my friend who has a copy of windows.

I have the same problem, Almost same spec

3.0ghz Quad core
Nvidia 9800gt
4ghz Ram

I have tried formatting and reinstalling windows 3 times now. Same issue over and over again.

When playing COD4, Rogue Spear, R6 Vegas, it plays fine for a little while like it should on this system. Then 30 mins or so later the crashes begin. The crashes on rogue spear go like this.. it'll halt the game and u'll hear the sound looping (usually someone has talked on vent during the crash and i just get their first words repeated over and over again. Sometimes i manage to get back into windows and it seems to be all good, untill i try relaunch the same game again and i have to reboot due to the same problem but this time as soon as i get into the game. After a restart it'll play for a further 10-15 mins then crash again in the same fashion and i'll have to do a finger push reboot.

CoD4 is a little more dramatic. It does the same thing as Rogue spear but it wont get back into windows i'll have to do a finger push reboot.

I've been through hundreds and hundreds of forums looking for someone with this exact same problem, although i have found hundreds with the same problem, none have given any way to fix this problem, and formatting /reinstalling windows hasnt helped at all.

Any idea's guys?

Sounds like the nforce lockup issue; the P5n-e is a 650i based chipset, and this sounds just like the lockups other nforce users are running into.

Try giving more Voltage to RAM/NB/FSB and a 1:1 FSB-RAM ratio. Other then that, I don't know any surefire fix, except to get an Intel based chipset.

Just google (without quotes) "nforce lockup" or "nforce freeze" to see what I'm talking about. I went through the SAME EXACT THING, only I've managed to get stability (went from twice a day to once over the past 4 months)
