Download memtest86 (www.memtest86.com, chose ISO, burn a boorable CD) and test your memory.
BIOS voltage readings are notoriously inaccurate.

It’s time for a Mac.

negative -61.34 volts??

umm....it’s supposed to be -5v

Sounds like a bad regulator to me.

“Then I installed Kubuntu, but again, the problem persists.”

I have a feeling we will be hearing this out of Obama someday.

Ditto what AmericaUnited says. Random reboots often, not always but usually mean a memory compatibility problem.

I recommend a 12 gauge blast right near the power switch. If that don’t get it, repeat near the fan. ;-)

I would do the motherboard anyway.

Don't know if this will help. Hopefully...

Turn off the automatic reboot feature so you can actually see the error code/STOP Message when it happens - this is also known as the Blue Screen Of Death (BSOD).

To change the recovery settings and Disable Automatic Rebooting, go to Start > Run and type: sysdm.cpl
Click Ok or just press WINKEY + Pause/Break keys to bring up System Properties.

• Go to the Advanced tab and under "Startup and Recovery", click on the "Settings" button and go to "System failure".
• Make sure "Write an event to the system log" is checked and that "Automatically restart" is UNchecked.
• Click "OK" and reboot for the changes to take effect.

Doing this won't cure your problem but instead of crashing and restarting you will get a blue diagnostic screen with an error code and other information that will allow you to better trace your problem.

my experience is random reboots are generally heat related.
though I’ve found some weird solutions to random reboots.

- once I swapped out the power cord on an AMD box and the reboots stopped.

- though reboots are not a symptom, I put in a new CMOS battery on a P4 and the reboots stopped.

P4’s generally slow down to 1/2 rated speed when overheating.

however, you might try

- cooling fan could be going
- thermal pad/paste could be cooked. you could try and repaste the cpu.

- though it’s not recommended, you could open the case and run a small table fan over the insides while the PC’s running and see if the the reboots stop. ( opening the case could actually increase the heat.)

not much...good luck

random reboots = bad RAM

The last time I had a problem like this it was the CPU fan. I would check the event viewer for errors.
