The other day I was trying to boot up my old computer and all I get is the cpu fan spinning like crazy(and the other fans) and a constant beeping noise. I made sure all my memory was in place and everything was connected right. I even took the memory and cables out and put them back and still no success. Then I take out my cpu and to my horror a single pin is missing. Does that have anything to do with the computer not booting up?? If the cpu is ruined then tell me how to tranfer my old hard drive to my new pc.
It's probably either a memory problem or hardware problem. Is this a pre-built computer or homebuilt. Check your motherboard manual or manufactures website for more info. The number and length of the beeps will help you pin point the problem.
