I noticed noone mentioned how to reset your bios... the easiest way to do this is to remove the battery for 10 to 30 seconds. also to check your processor for errors, if you are able to load windows use a program called Prime95 good luck!
also remove all unnecessary components IE: wireless adapters, NIC's, CD, DVD drives, while troubleshooting. this will determine if one of these is potentially creating or adding to your problem.
The batter will be round and silver. Take it out for a minute and put it back in. I have had this similar issue, when I lowered the temps in the bios. You may not be seeing this option because you are "new", or your mobo doesn't support it. Do you have the mobo manual? Also to reset the processor, just take it out and put it back in.
