Like every morning I turn on my computer (which is kinda new and only couple months old) and I never had any issue with it until now. It starts booting, shows that very first screen which has some motherboard picture and stuff and then it show which buttons to press to enter BIOS and etc. Then it suddenly restarted and after that just kept restarting every 3-5 seconds forever.

What could that be?

I unplugged power cable, checked all the cables, moved a case, it had some wires stuck under it, blew some dust (but didn't open the case yet) and I tried to boot again and it booted successfully and I am writing this issue now.

My specs: i3-3220 3.30Ghz 8GB DDR3 RAM 1TB HDD GeForce GTX 650 Windows 8 x64

I also recently upgraded my security software (that's the most recent thing I did) and it includes ZoneAlarm firewall, Comodo Antivirus and Spybot Search & Destroy. But maybe it doesn't have anything to do with this.

Cheers
