Today my new CPU arrived. It is Intel i5 3570. I put it in my motherboard but when I turn PC on it just beeps a few times and then restarts and repeats this over and over again. I checked my MSI H61M P22 (B3) supports I5 3570. No idea what is the problem. Please help. I can't sleep at night.

I have V25.4 or something like that. But i thought you update bios after switching for a new CPU. And now I can't even access the bios. :( So should I put in my old cpu and then update to the new bios?
