Urgent !!!!! my PC restarts it self

[vianey8386]

:eek: Hi I'm new at this, and I really need your help: I don't know why but every time I turn on my computer and enters the system it just lasts about 15 seconds inside and then restarts itself. I have no idea what's going on. Please help me as soon as you can, any advise is welcome. Thank You. :(

Welcome to the PC Guide Forums!! :D

This problem could be many things, from a stuck power button to a virus. Gonna need more info about your system - OS, hardware, things that have changed recently, security on that system, etc. Also, explain the problem more clearly - when you say it "enters the system" do you mean the BIOS or the POST or Windows or what?
