CMOS SETTINGS WRONG

Okay this is a bit confusing…
I am getting these errors when I boot up
CMOS Settings wrong
CMOS/GPNV Checksum Bad
CMOS Display Type Wrong

It gives me the option to hit f1 for setup or f2 to restore default values. When I hit f2, it just sits at the start up screen ,detects the hardrive and then just sits on that screen, it doesn’t freeze, because the cursor is still blinking. I got a new CMOS battery, put that in, still the same errors. I removed the jumper to reset the bios, because I coudlnt’ even get into the bios because it was password protected. Now I’ve hit F2 to restore settings it won’t even turn on now.
Any suggestions I would REALLY appreciate it
Thanks.
