My computer resets with no apparent reason.

What I said: y PC restarts with no a logicall explanation. I'm reading a web page or word doc, and flop!, it resets, as I would have pressed the reset button.

I haven't used this pc in months, so my family hasn't made repairs or maintenance to the pc. I noticed that this problems happen when the Computer is connected to internet.

Only 2 programs have been instaled since my last use; Kapersky anti-hacker and Google Earth.

Faulty memory will in the vast majority of cases lead to disability to boot altogether. You can still run some memory diagnosis programs for the fun of it, though.

About the overheat issue: Check if the cpu cooler is full of dust. If it is, vacuum clean it. If it isn't, your cpu won't overheat if it didn't use to from the very beginning.
