How about the power button interrupt to shutdown/restart?

First; memtest.

Next, boot in "Fail Safe" mode which is almost conservative in the
extreme about how the kernel talks to the hardware.

Add the "irqpoll" kernel command-line option at boot time.
Add a "3" to boot without GUI; worthwhile if you're uncertain about
the graphics chip.

The irqpoll option seems to work well with a lot of hardware that I
deal with in which interrupts just seem to get lost. NVidia chipsets
seem more prone than AMD when there's an AMD processor.
