no virus i just scanned it..
i just updated windows (this used to happend even before i updated)like last week, i havent download anythin that can harm it, no new software, no message before it reboots, and i dont shut it down, it does it byt it self, i try other p2p's but some never connect(Ares), lime wire doesnt have wat im looking for, bearsshare had everything i neede and fast downloads.
something i just remember is that when it did it the first time, i tought it was the power supply over heating cus the fan wasnt working and it got to hot and had to shut down. so i unistalled bearshare and fixed my power supply(2 days ago) so i said ok now the power supply works so it wont do it, i installed bearshare again and same thing over and over...
