One of my computers constantly rebooted when

by pennatomcat In reply to rebooting PC

the fan in the power supply died.

It might be possible that you're exceeding the capacity of the power supply.

Using the same type of RAM, but made by different manufacturers gave me problems once. The RAM tested ok repeatedly!

Capacitors

by dan.cox In reply to rebooting PC

Look on your system board.
Check out the capacitors. If any of them are bulging that could also explain the rebooting. If this is the case than you need to replace your system board.
This was common on both Dell and IBM computers.

See this site for an example.

processor temp

by Absolutely In reply to rebooting PC

When the PC is moved or after years of use, the thermal grease may no longer make contact between the heatsink/fan and the CPU. Enter the BIOS, if possible, before the computer reboots, and look for the CPU temperature. Around 80 C, many computers reboot automatically to avoid overheating damage to the CPU.

Check your bio settings

by jdclyde In reply to rebooting PC

Many bio's have a setting for the temp to shut down at certain temps. if this setting is too low, it is easy to hit after a while, especially with older AMD.

Have you also tried blowing the system out and making sure the fans are all working properly?
