If you look at HP , HP owns COMPAQ, lock stock and barrel.
you'd see it there, if still there, if not its RETIRED now

Yes, the CMOS battery is replaceable, and easily so. Just remove the old one, go down to an electronics shop, get a similar battery and replace it.
Unfortunately, we just provide online help, and cannot physically come there and do this for you.
Here are two online tutorials that explain the procedure in detail:

Shut down the computer--remove all the cables frm tower--hold on the power button for 20 sec and then release it and then plug back the cables and restart ur computer.
When back to desktop---check if u have more than one anti-virus and/or more than one anti-spyware/trojan and/or more than one software firewall program running at the same time.Un-install any similar you aren't using.
-- Uninstall any Programs you don't need anymore .
-- Try Disk cleanup ,disk fragment.
-- Finally if nothing helps.Download a Program Called SDFix and Install it.
Then Restart Your Computer in Safe Mode. (Just Restart Your comp and press F8 Before the Windows Loading Icon)

This should fix the problem.
