I get a "bad bios checksum" message at power-up.It then displays "starting bios recovery,checking for floppy ...floppy not found! checking for cd-rom,cd-rom not found." It keeps doing this sequence over and over again.I have a compaq presario S5322SS running xp home edition.This happened out of the clear blue,no previous symtoms.Any help or sugesstions would greatly be appreciated.Thanks,Ralph.

Hi,
is this a laptop/notebook or desktop pc?
The compaq presario S5322SS doesn't seem to exist.

If it's a desktop pc, switch off & unplug from mains, remove the motherboard battery for 5 minutes, replace and boot up.

Hi,
Do you have BIOS Recovery software on disc?
I take it you haven't, so, when the pc starts to boot enter the BIOS Setup and select your default settings then save & exit.
It tells you onscreen what key to press to Enter Setup during the initial stages of boot. It's usually F2, F10 or Delete.

Hi, is the pc also starting-up without you using the Power button on front of the PC?
If so, you'll need to power-off, unplug from the wall and check every connection on the motherboard is properly made. Especially the front-panel connectors.
Remember the anti-static rules and discharge any static you may have on you by touching the power supply and chassis and keeping some skin in contact with the case while your hands are near the motherboard.

Use the manual to guide you with this. If you don't have one the download it.
Here's your pc's page at Compaq.

Did this happen after you tried a bios update? If so......
Cmos battery might be dead.
