What could cause a system reboot after 1 - 2 hours uptime?
+1 for booting via live CD. The intention here is to test/rule-out one thing at a time using known good 'other bits'. In this case, we can assume that the software/OS running from the live CD is good, thus if it crashes using known-good software/OS (the live CD) I believe it reasonable to assume a hardware problem. If it only crashes when running from your normal OS, I believe it reasonable to assume that something running in your day-to-day software is causing your problems (else exacerbating to the point of crashing).
Why is my computer really slow despite of having a considerable amount of free memory?
Careful @Joel - some people might think you are being sarcastic!
