Why wont my PC start up correctly?

by travisdreams / August 28, 2014 1:10 PM PDT

I get the usual start up (f10 and f2 for setup menu and bios)

then i get a screen that says "CMOS checksum error - Defaults loaded"

i read that i needed to replace my CMOS battery, though i put a brand new one and i still got the same result?

if i press f1 to continue, it will ask if i want to boot by CD or not by pressing any key. Though if i just let it go, it either blue screens or goes to a black screen and freezes on that screen. Any idea on what exactly i should do to approach this?

I was thinking of taking it to a specialist if anything but i think it costs to have them check it?

Details - are we to guess?

You gave no clue to the PC invoked, OS, age and in general if this just happened.

If you haven't changed the bios battery, then do so. Re-enter the bios and reset to the parmetyers they should be and save them upon exiting. Then reboot and check results. How long has the problem appeared. Did you do anything majort before this? Did, a electrical storm pass?

You need to short the CMOS chip

some errant erata has gotten stuck in it where only shorting it will remove it, although replacing the battery should have accomplished the same. That message is also an indicator of some device problem.
