✔ Best Answer
Typical cause is the cmos battery needs to be replaced. There are other possibles too, but the battery is the first in line of fire...

This link discusses it all battery included.

If you're seeing "CMOS checksum bad", it should appear before the Windows logo. In fact, the boot process usually stalls at "CMOS checksum bad" with a couple of choices such as:

Press F1 to run setup
Press F2 to load defaults & continue

Please explain more clearly what is happening & it would help to post your system specs, or at least the make/model of your computer.

After all that you've shown in that pic, only that mine displays it differently, f1;continue f2;setup, whichever one I go with it runs a check on D, NTFS and after checking all sectors it get stuck with all the info displayed. It stays that way and nothing else happen.

And what happens if you replace the cmos battery with a new one?

"whichever one I go with it runs a check on D, NTFS and after checking all sectors it get stuck with all the info displayed"

You're still not being very clear. As trvlr stated, the CMOS battery should be changed. But afterward, you will still have to press F2 to enter the BIOS & correct the settings.

What is "D"? Windows is usually installed on "C". Do you have 2 HDDs? If you do & the 2nd HDD is "D", try temporarily unplugging it - it appears to be corrupt.

It's telling you what the problem is - the keyboard. Is it USB or PS/2? Try a different one.

Is this a desktop/tower system?

I crossed with riider... with my query re' desktop system. Presuming it is, replace the keyboard - preferably a non usb type, if the system allows.

OK - borrow a known to be good usb keyboard; ideally one that doesn't require an adapter for ps/2-usb - but rather a simple usb connector.

Keyboards can die like most electronic and electro-mechanical devise...

After doing everything you've told me I feel I've moved closer to getting reed of the problems I've been facing with my xp. Now only one thing I need for you to help me with. After windows does a complete check on my drive and confirm no problems found the report remains on my monitor blue screen and stays there and nothing happens after.
