Have to RESET motherboard jumpers every startup

I've run into similar problems a few times and it seems it was caused by something different in each case.
I had a motherboard that shipped with a defective battery that caused symptoms very close to what you describe and replacing the battery resolved the issue.
On another board, it was the board itself that was bad...this one also produced cpu, keyboard, and mouse errors. Replacing the motherboard resolved it.
On yet another machine, it was the CMOS chip itself that was bad...I also replaced the motherboard on this one and solved the problem.
That said, there should be a setting in the BIOS Setup for "Halt On". If the keyboard/cpu errors are caused by drivers that aren't loaded early enough in the boot routine, changing this setting to "No Errors" (or similar) should allow the machine to move on and load the drivers.
I'd try a different battery and change the Halt On settings in BIOS first to try and eliminate a possible problem with the motherboard.
As a side note, bad RAM modules can also cause similar issues, though I've not seen that cause keyboard or cpu errors.
