4 Beeps system timer failure

[nacos]

Last week I performed an external build on my computer and instead of posting, it gave me 4 beeps which according to the bios it has means a system timer failure. The most common answer I received was that it was a defective motherboard. Today I received a replacement motherboard and I am getting the same 4 beeps on an external build. Could a different part be defective? Please help.

Oh and I was not able to reset the CMOS because I did not receive (or cannot find) a jumper. Is one supposed to come with the motherboard?

When you did your external build for POST, what components did you have plugged in/hooked up?
What mobo are you using? CPU? PSU? ram? CPU cooler?

Alright I figured it out. It was one stick of RAM that was defective. I had tried using only one stick of RAM before, but I hadn't given thought to the idea that one specific sticks of my dual channel ram would be defective. Thanks for the help though.
