Just bought a GByte GA-P41-ES3G and fitted CPU Intel 430 LGA 775.\nCPU fan only spins a few seconds then stops. Nothing on the screen, no\nbios display. The PSU is a bog-standard 20 pin plus the extra 4 pin\nplug nr the CPU. Should I invest in a 24-pin PSU, would it make any\ndifference? Do people use a 24 pin PSU AND the 4 pin 12V plug?
