Been having the same problem, game freezes randomly. Then have to ctrl + alt + del to get out. But can't kill the process after. Have noticed an error message sometimes that the Nvidia driver has crashed and recovered or something like that. However, what is strange is that a lot of games work just fine. Even, GTA IV and Crysis 2 that crashed in the video's here l502xcrash.blogspot.com worked fine on my system, but other games like Deus Ex: Human Revolution, 40K Warhammer and strangely even Half-Life 2 tend to freeze up.
i m also having the same problem.The screen becomes white.Then i have to hold down the power button.This thing started after installing call of duty black ops.
Interesting even my laptop started having problem after installing black ops...Before i played Borderlands, Dead Space and Crysis for hours without any issues...anyone else had the same issue...???
No everything is fine after replacing my motherboard...I was just mentioning how the problem started...Replacing your motherboard seems to be the only solution..
It fixes about 90% of the freezes, it still occures. And it will still make that sound trough your speakers when you load websites sometimes. I can recommend it but dont think it really is fixed
They replaced my MB last week. It seems that the games are working fine, but I lost audio. I tried everything, like drivers, upgrading and downgrading bios, etc...
Finally called Dell, and they said that the MB has the audio chip screwed.
I havent played much, because without sound, whats the point.
Finally They replaced my motherboard today,
it seems that everything works fine now 🙂
i hope this problem will not appear anymore.
@entimus - it's happend some time after they replace your motherboard or it's from the beginning? i hope my audio chip will not screwed too, now everything ok.
