[Ask] My screen suddenly got froze

[Morning Star <morning.star.crew@gmail.com>]

Hi guys,

I have a problem about my cpu. After 15 minutes or more using debian squeeze in KDE display manager, my screen suddenly got froze. I can't move my mouse's cursor and can't type anything on my keyboard. caps lock and num lock lamp wasn't responding. I had to reset my PC, then selecting the same OS to boot, and then I happened again after that. It happened like this: BOOT --> X-SESSION --> FREEZE --> RESET --> REBOOT --> X-SESSION --> FREEZE --> .........

Here are my�specifications:

OS : Debian Squeeze

my kernel :�2.6.32-5-686

my VGA card :�GeForce 6600 LE

my video driver : NVRM: loading NVIDIA UNIX x86 Kernel Module �195.36.31

My�Xorg.0.log :�http://pastebin.com/Xr5kV4Rf

My Xorg.0.log.old :�http://pastebin.com/UctMDRv5

It frequently happens after i installed my video driver using NVIDIA kernel module�195.36.31. When I used nouveau driver, same thing happened again. Is that a OS problem or hardware problem? I'm sick about this endless freeze. Please help me.

Thanks in advance,

Marco
