I was wondering if anyone could help me understand why my pc just turns of when it feels like it sometimes it could be around once an hour some times every few mins and sometimes it could last a day before shutting down and restarting. I have ran adaware,pandatitanium,housecall,spy bot, I used hijacker got rid of a few things I didn't reconize but most stuff looks like it belongs. I also have startup monitor on my pc along with spyware blaster. If anyone can figure out what would make my pc do this I would very much appreciate your help. My pc is a compaq 900 MHz 128MB RAM, 40 GB ultraDMA I am running XP not sure if this info helps but thought I would put it in incase. Thank you for taking the time to read this any help would be great.
