Hi everyone, I hope someone can help me with this weird problem! Basically, a few months ago I built a PC for my aunt, and the other day she rings me and says it has been restarting itself and wont turn on... I think dead mobo or something so I get her to bring it over. It works fine and there are no issues or anything, run a few virus/spyware scans just in case, nothing there. So she took it back and apparently it got even worse, restarting every few minutes, sometimes not powering back on and one time there was a scrambled display before it restarted.... She also said the more she used it the more frequent the crashes got, and that it usually crashed when it started doing something 'like going on the internet', I dont know if that's really significant though. She dropped it off with me this morning and I have been testing it out all day, it seems perfect... I cant see any problem with it... Here are the rough specs: P35-DS3L mobo E2160 2gb 800mhz ram 700W (lol) FSP PSU Passive 3450 Everything is at stock and temps are fine. I have run memtest for a few hours, no errors... I cant really think whats causing these crazy problems... It sounds kinda like a power issue, maybe the electricity in her place isnt that great or has surges or something???? She also uses a USB printer, could this affect it, maybe dodgy cable or something? Please help!
