CPU good or bad?

Specs: Windows 7, 2.4 Core 2 / 6 gig
I recently got some parts cheap and finally got around to seeing if I could put something together with them. The MB is an Asus socket 775 and the cpu is a 3.16 gig core 2 duo. When I tried to boot I get the asus screen with the options to press delete to enter setup or press tab to see the post screen. I tried three different keyboards and got nothing so I gave up for a bit. Someone gave me a 2.4 gig core 2 duo that they said was good when they pulled it so I tried it and it worked. Could the 3.16 gig be bad even though I did get video? Or could it just have been the cmos needed clearing because I did remove the battery for a few days?

Does the MBoard have a PS/2 keyboard port? If so, use a PS/2 keyboard. You may need to enable legacy USB support in the BIOS.

The BIOS version may not be able to configure the faster CPU without a BIOS update. Hard to say without a model number and version for the board.

It's always helpful to provide model numbers - Asus has made a heck of a lot of boards. Did you check the CPU support list? If you're getting a display on the screen, the CPU is good. And as OtheHill said, if your board has a PS/2 port for a keyboard, that's what you should be using, not USB & not an adapter.

BTW, you do not have to wait days, hours, or even minutes to clear CMOS. It will clear immediately if the Clear_CMOS jumper is used (or the battery is removed), but the power cord MUST be unplugged 1st.

I tried two PS2 keyboards and got nothing as well as nothing with a usb keyboard. The usb keyboard did work with the 2.4 gig. I did not keep the battery out thinking it took that long I was using it in another board that did not have one. At the time I thought this one may have been a wash.

Still haven't provided a model and version for the motherboard. The CPU may not be compatible with your BIOS version.
