Crash to desktop

anyone experiencing this? it happens randomly but what pisses me off is that for me it happens when the game is exciting (ie close games or me coming from behind) i know its not related but this crash to desktop thing is starting to get annoying

specs

e8400
GeForce GTX260
4Gb OCZ PC6400
600W OCZ StealhXStream PSU

im pretty sure its not hardware/heat related as my other games run without crashing (Crysis Warhead, GRID, FarCry2 and SimCity 4)

any tips to avoid CTD?

maybe sounds card drivers , same problem here

but I have onboard sound

oh well maybe its worth a shot installing t he latest realtek driver

what annoys me is that the instances it happened, were all exciting games lol and on games where Im losing badly it dont crash lol

lol !!
maybe the computer doesn't like to lose !!!!
u're lucky i can't play an entire game ! the only game i was able to play is when my soundcard wasn't installed lol
i have a realtek high definition audio

wait, you mean you have an add-on card and if you use it you cant play hence you use realtek HD audio (onboard) instead?
whats your soundcard BTW?

this is really frustrating and i hope they get to fix this issue

i'm like you , i have a onboard sound realtek alc662 @nvidia mcp61
and maybe another one but i'm not sure
ait radeon hdmi @ ati rv770 and both are high definition audio controller

well i just installed the 2.10 drivers for realtek HD audio so lets see what happens..
