Random XP Shutdowns

Recently a client called because their system was randomly rebooting while they were using it. If a problem happens every time you perform a certain act, like run a program, open a file, turn on a piece of hardware, etc, it can be reproduced. This allows you to eliminate possible causes. But if a problem just randomly occurs with no apparent cause, this is typically harder to fix.

This was a Celeron system with 256mb of DDR in the form of 1 Dimm. This is a really low amount of memory for a Windows XP system. XP needs at least 512mb to run reliably and more like 1gb to starting running well (more than this will only lead to minor performance enhancement unless running memory hungry applications).  The initial recomendation was to install a 1gb Dimm. This improved performance by reducing the computer’s reliance on virtual memory.

The client contacted us la few days later and told us that while the computer was faster, it was still randomly rebooting. We returned and decided that the system could be suffering from overheating issues. The CPU fan was removed and a considerable amount of dust was blown out. The existing heatsink grease was wiped away, replaced with fresh grease, and the heatsink was reinstalled. The rebooting issues seem to have been resolved.
