hi i have a asus A7N8X-X motherboard and have fitted a 2800+xp amd processor to it when i turn it on it starts and about 5 seconds later it turns off all the fans run ok but the hdd doesnt spin up can any one help me
First check that all cables and connectores are full y home. Next check that the new processor is making good contact with the heatsink and that you haven't bent any pins. Also check that you PSU is powerful enough for the new processor.
If that doesn't help, then remove everything from the motherboard except the ATX power connector, processor with heatsink, power switch and case speaker. You should then get an error beep to tell you that there is no memory or graphics card. If you don't, unscrew the motherboard and place it on a sheet of card or other insulating material. If you still get no joy, then the problem has to be in the motherboard, case speaker, power switch, PSU or processor
