How do you know if you CPU is bad? Does the mother board beep?

It's almost impossible to tell if it's the cpu or the motherboard or both that have gone bad


You need to visually inspect the cpu and look for signs of overheating, if the heatsink fan quit working there will be signs of the thermal paste actually melting. Look closely at the motherboard for signs of burns or leaky bulging capacitors.

If the computer is too old I just throw both away, maybe save and later use to troubleshoot with?

About the only thing you can really do if you don't see anything wrong is try another cpu or another motherboard.

Clearing cmos and making sure jumpers are set right and all connections are good, there's a lot of things that can cause a computer to not post(first screen to show) where you get no beeps at all.

No. Try not. Do... or do not. There is no try.

I have test boards that I use. IE I have a socket 478, Socket 370 (dont use that one often), Socket 939, etc.. with at least 1 ram module. I know these boards work so I can swap in parts and see wich one causes the system to fail. Its an expensive option which is why shops charge a bench fee (it pays for the new parts they have to keep buying to keep up with technology)


Edit: it also helps to have an external speaker handy to plug into the connector on the MB so you know when it beeps or not.
