I think I have a hardware/electrical problem.
My Windows XP PC periodically starts rebooting instantaneously, with no warning, as if power were quickly switched off and on. There are no warnings in the system logs. Virus/adware checks come
up clean (using Norton anti-virus & multiple spyware programs).
I would like suggestions, wondering if I might have a flaky power supply or an intermittent short circuit.
A few months ago it started rebooting frequently (several times an hour). Swapping a flaky CD-Rom drive
fixed it. Last week it started rebooting again (several times an hour). This time, it semi-fixed when I pulled the fax/modem card. However, it still reboots, maybe once every 24 hours of use. Could there be something more than these components going bad, like a flaky power supply or whatever? Are there tools and/or techniques I can use to analyze this?
It's an HP Pavilion/AMD processor, about a year old, no add-ons besides what was factory installed.
Thanks so much for all suggestions.
