I don't know where else to put this. At night my computer starts beeping. It gets faster and louder. Lastnight i had to turn it off 3 times before it would stop.

could be to do with anything are u in windows at the time or is this at post?

could be ur ups !!

if it is a laptop it means the battery is low. or if it is a base unit it could be to things the fan, or your power and mother board or going on the blink. i had the same propblem
