1.	Solve : computer powering off and on rapidly?
Answer» I was watching cinemanow and shut it down along with window media player and my computer was working fine. I left for dinner and when I CAME back the computer was powering off and on rapidly. I had to do a force turn off by pulling the PLUG. I opened the case and pulled a reset the memory sticks and cleaned out the case. When I turn it back on the fans are running but thats it there are no beeps and nothing comes up on the screen. I have and ALIENWARE tower computer, running windows home edition. It has 256ram ddr memory and 128 ram ddr memoryDo you have virus protection software installed? [glb]Flame[/glb]Also, is it a dual cpu system...and are they being over-clocked...wait a minute, yes they are its alienware. But it could have a virus, but I think it could be problems with overclocking. TALK to alienware...they have good support!
