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.
