My computer's been crashing and rebooting by itself. I usually leave it on for torrents download. I don't know what's wrong. I notice the RAM is always above 60%. My RAM in 1 gig, but it seems much slower. I cleaned my register using Uniblue Registry Booster 2. There was like 800 errors! Is it PC-Cillin that is hogging my RAM? Malware/spyware that isn't detected? PLEASE HELP. Thank you
