How old is it? Look over the motherboard carefully for bulging or leaking capacitors. Google "bad capacitors" for some images of what they can look like.

It's only 2 years old and no bad capacitors

Did you actually replace or simply remove/reinstall the existing CMOS battery? A CMOS checksum error is indicative of a weak or dead CMOS battery.

Straight from Dell's documentation. 5 beeps = replace CMOS battery. Where did you get the 'new' one?

If we make the assumption that the replacement battery is good then the next course of action, according to the troubleshooting guide linked above, is to contact Dell. There may be a failure on the motherboard.

Even if I don't put a battery it still beeps so I do believe its motherboard failure it's it possible to fix it?

Yes, replace the motherboard. That's why you contact Dell.

sometime you can fix a damaged bios by re flashing it. most time cmos checksum error is a bad cmos chip. on some mb you can pull the chip some of them there solider on.
