Random Hibernation/sleep - Need help.
 

Ok, so this was a problem that happened from the beginning once I bought the computer. It didn't bother me as much, but now it's just getting annoying.

Every time I go away for 10+ minutes, my computer hibernates/sleeps for 1 minute max and then wakes itself up without my touching anything. This is a problem when I'm downloading something and it hibernates aka stopping my internet connection.

I am asking if there is anything I can do with the setting on the computer or is it the hardware in the computer that is messed up. Running a Vista atm.

Please and thanks.
