  1. Whats your PSU(make/model)? Have you tried playing with only 1 gfx card inserted?
  2. Download nTune from nVidia 's site and lower the clocks on the video cards. See if that fixes it.

    Try with a single card too, like MaDMagik said.
  3. @MadMagik, ty for reply, yes i have tried to play with only 1 card.
    My PSU is

    @aevm will try again, done that before with winfox
  4. That GameXStream 700W is more than enough for 9600GT SLI. We can rule out PSU overload IMO. It's a good brand too.
  5. Yeah, it is a good PSU. Dont know what else to suggest - maybe stress test it with prime95 and watch the temperatures. Although rather unlikely, it is possible that your hsf isnt seated properly, causing the cpu to overheat . On my system COD4 taxed the cpu way less than Crysis for example. "40-50" - are those temperatures with cpu idle or under load? Also the mobo temperatures seem a bit high to me but I never dealt with nVidia based mobo, maybe thats normal.

    Have you tried previous versions of gfx drivers? My radeon 4850 seems to take a performance hit in Crysis with latest driver release, so im using the previous version instead. They dont always improve things for everyone.

    So, apart from that in-game crashing issue the PC works fine? And does it crash immediately after starting the game or after a while? Can you play at all?
  6. Its been ages, my apology. I am now running win 7 64bit, in raid 0 and the game that never done this before, ever, World of warcraft, craps out on me. I will try to get video card from my friend today, ati 3850 and see if it does it as well.

    So, apart from that in-game crashing issue the PC works fine?


    And does it crash immediately after starting the game or after a while? Can you play at all?

    it takes an hour or so
  7. i borrowed 3850 from my friend. and installed it with latest drivers.
    I was unable to replicate the error, i played wow just fine for about 3hours straight
    i also have downloaded a game(airrivals) that ALWAYS crashed within 5 minutes. but even in this game i wasnt able to replicate the error. i will try to switch back and see what happens
  8. Hi there, sorry but have been away for a while myself. While you have your both cards out inspect the HSFs if they sit properly, maybe one of them is not and causes the crashes after some time(due to overheating).
  9. <-- 1 radeon <--- 1 9600gt

    Normal? bad? wtf?
    now one game plays good, UT2004 fails :(
