I have a system that was running a Q6600 and Windows 7 RC. It crashed last night into a BSOD with a MACHINE_CHECK_EXCEPTION. Now it does that every time it boots into Windows.
I tried using my Ubuntu Live CD, but the kernel would error out, the stack trace showed something along the linse of "Can not synchronized to one of the CPUs".
Working from this, I enabled the "Limit CPU to 3 cores" option in my BIOS and tried again. This time, it seemed to have died after an ACPI call, so I disabled that during the boot and now it is running from the Ubuntu Live CD, showing 2 cores.
Does anyone here think I have any hope or is it simply a CPU waiting to die?
EDIT: 1 core now.
