Hey guys,
Today i upgraded from my g2030 pentium to an i5 3470s. I removed my old cpu and installed the new one, with paste and heatsink. After connecting everything back and turning it on, the pc wont boot. It just gives me black screen and it restarts after about a minute. The cpu fan spins normally. Ive put back the old cpu and it works normally. What to do?
My mobo is msi h61m-p31 (g3)
