At the meeting before last, I asked about a problem I'm having with the
computer occasionally going to a black screen with no disk activity on
reboot, right after the grub menu goes away.
Overnight memtest showed no errors, I put a different vid card in, and
still had the black screen problem.
One of the things someone mentioned was to test the power supply.
Recently, I had a few hard lockups and a couple of spontaneous reboots.
So, how do I test my power supply, other than replacing it and seeing if
the problem goes away? Or is that evidence enough to change it ASAP?
According to lm-sensors, voltages are fine, and I've even sat and watched
gkrellm for long periods of time - they look stable.
Any suggestions would be appreciated.
