Error: please re-setting CPU or memory frequency in the CMOS setup

[new player]

My CPU was running hot so I removed my motherboard in order to remove and clean fan and heat sink. Put everything back together and when I start PC I get

please re-setting cpu or memory frequency in the cmos setup

Press F1 to continue, DEL to enter setup

Pressing F1 will work and take me to windows, but the program that monitors temps and fan speeds crashes (computer continues to work)

Pressing DEL only takes me to a blank screen with a blinking cursor in the top left hand corner.

I've been thinking about resetting the CMOS by removing the battery. But I'm concerned that if I can't get into my BIOS my computer will be completely unusable. Any help would be appreciated. Thanks in advance.

What is the make and model of your motherboard?
We may be able to find directions to reset your cmos to factory default.
(Or... you could google for a manual for your mb.)
On some mb's removing the battery is the best way.
On others, there are a couple of pins on which you can place a jumper.
Curious that you are able to boot to windows, but not get to Bios Setup.
