CMOS checksum error

[Jiess]

Problem. I recently upgraded my system and I think maybe I damaged something in the process. Whenever I boot my machine now my system beeps as if there is a non-functioning component. I get a CMOS checksum error, and "your processor is unworkable or has been removed." Its also not detecting my IDE connections.

What the heck did I do

had a AMD Athlon 3000 socket 939 Venice core. Upgraded to a AMD athlon 3200 socket 939 venice core. 6600 geforce to a 7800 geforce pci-express. Added a gig of ram. I attempted to put the old parts back in but i get the same errors.
