Hi people, my system just crashed (it seems to be doing this a lot recently. Sometimes Firefox will seg fault and then when I restart it, the display screws up and the system crashes) and after rebooting, I'm unable to start my X server. I get the following error message:

Fatal server error:
Caught signal 8. Server aborting.

(More stuff about contacting the X.org foundation)

XIO: fatal IO error 104 (Connection reset by peer) on X server ":0.0" after 0 requests (0 known processed) with 0 events remaining.

Again, my graphics card is a GeForce 6600 256 MB and I'm using Nvidia's driver. Actually, I tried changing the driver in my xorg.conf to vesa (as I was using that before installing Nvidia's, but I've been using Nvidia's for a while now) and the same thing happens. However, when I do try to use the vesa driver, I notice a warning in my Xorg.0.log:

(WW) Bad V_BIOS checksum.

There's nothing on LQ about the "caught signal 8" error, well, I found one thread but that was about trying to install the Nvidia drivers. Google's not helping me much either.

Can anyone shed some light on this? Thanks.

I would try the "nv" driver.
If it does the same thing may be a hardware issue.

Oops, I should have mentioned that I tried nv as well and the same happened. Anyway, I think I may have found the problem - CPU overheating.
