Agreed. That's a very low end board, (it even has a serial port on the back panel), and the chip not being listed is not a good sign. The latest BIOS update being from `08 is worse.
Oh man So much for wanting to upgrade my CPU. Thanks for all your help though.
Is there any easy way to replace my motherboard, or is it not worth the effort? I'm leaning towards just waiting and buying a new computer in a year. Wonder if I can sell the E5400 on ebay.
Honestly, just wait. The E5400 is not a major upgrade for you. I'd sell the proc on EBay and wait to get a new PC next year (if that's what you were thinking). This time next year, you should be able to put together a nice i5 at a real bargain!
