A few days ago my computer started acting weirdly. XFree86 hangs and I can't do anything at all but to reboot the computer. Ctrl-Alt-F1, Ctrl-Alt-BackSpc and similar combinations doesn't work and I can't move the mouse cursor. It just freezes totally so I have to press the button to reboot it.

Can't find anything in /var/log/XFree86.0.log or /var/log/messages that look strange. I don't know what is causing the crashes either. It could be that it crashes when I do something CPU intensive or reading from the harddrive. Such as viewing movies or listening to music or browsing with heaps of tabs.

Also, the computer has worked for almost two years without this error and I don't think it is something I've done recently that could be the cause of the problem. Atleast it isn't the video card cause changing "nvidia" to "nv" in the XF86Config file doesn't help. All the cold reboots have done some strange stuff to my filesystem too I think cause now Linux refuses to boot. It says "EXT3-fs: write access will be enabled during recovery" and I think it tries to repair the filesystem but fails and hangs but thats another problem.

Specification:
Redhat 9
Kernel 2.4.20-8
XFree86 4.3.0
GeForce2 XMMS/AGP/SSE

BUMP

It sounds like a possible kernel panic. Did you notice the keyboard lights blinking at all? Are you using a stock kernel, or one you configured/built yourself?

is your computer on a network? try using ssh to control it from another computer and see if its running.

It is the stock kernel that is shipped with RedHat 9. The LEDs do not blink and when it does crash it really crashes all. I can do absolutely nothing except to cold reboot.

I am running a fresh install of Slackware 9.1, and as soon as i start x, the whole kaboodle crashes. No kernel panic, no error messages. sshd also seizes, and i can't initiate a new connection, and any pre-existing connections into the box lock up. I cant find ANY signs of where to start looking.
