Hi,

I am experiencing seemingly random freezes in Intrepid. It seems random since I can be in many different programs and the machine can be idle when it happens. This is what happens:

First the screen freezes (with desktop image) and the cpu light blinks heavily, then it blinks in shades of grey/black for 5 seconds, then I am left with a frozen screen with a big X as mouse cursor (which is also frozen).

When frozen, it does not respond to alt+SysRq+REISUB, but holding alt+ctrl+del for some time restarts the machine.

i've tried searching around for other threads but I dont really know where to start troubleshooting. Any hints in the direction of troubleshooting is greatly appreciated (like a log of what happens when it crashes? is that possible?).

Cheers!
