Hi Gurus.
Since several weeks ago, my desktop PC started to go off or restart itself for apparently no reason. Once it turns off, it doesn't go on again when I hit the power button UNLESS I turn off the main switch in the back for a while.
Sometimes it does that after being on for many hours, or just a few seconds after turning on. Sometimes it just goes off (and remains dead until I do the off-on with the main switch), or sometimes it restarts again and again like crazy. It doesn't seem to have to do with OS (XP prof in this case) since the computer goes off even before booting up. Another tip: in some cases, when it ressucitates, the date was set back to 2003.
Again, what is remarkable to me is that I have to put the main switch off for a while if I want to have any chance to get the computer up again. Otherwise it is completely dead.
I think that the obvious choices are the psu or the mobo. But I don't know what to change first.
Any idea on what could be wrong with my PC?
Thanks a lot everyone.
PSU: Powmax 350W
mobo: PCChips M810DLU with integrated processor (AMD 1200MHz), video, sound and LAN.
