It's almost certainly a dead BIOS.
What Motherboard is it? Brand & Model
Not much point in trying to flash it as it won't read the floppy in that state anyway. Even though it is sitting at the A:/ prompt.
If your board has a duel BIOS it may just be a case of swapping a jumper to load the backup BIOS.
More info about your board will help.

This error message means that the BIOS may have become corrupted.

You can try replacing the cmos battery, but if that doesnt work, then you will have find and download the correct bios flash file for your motherboard, and reflash the bios.

The 'boot block' enables booting to a floppy for the purpose of reflashing the bios.

You are in fact lucky that you can boot to a floppy, otherwise youi would need to replace the bios chip or the motherboard.

There are usually detailed instructions how to flash the bios included with the file download, but you have to get the precise file for your motherboard make, model and version number.

Hmm... looks like your PC is relatively new... is it still under warranty? Mucking around with a Compaq bios (through flashing, etc) generally voids any warranties... perhaps it might be an idea to take it back to where you bought it and get it serviced?

It sounds very much as though you need to take the computer in for repair/servicing, because the steps to go through will probably be too much for you.

However if you want to persist, first of all use Google to find your computer on the HP/Compaq website, then find the support page/downloads/bios.

Without wanting to seem awkward or snotty nosed , if that is too difficult for you, then you do need a tech to do the work.

I've just had exactly the same scenario on a 2mth old Gigabyte board.
Even though it says insert system disk (A) it wouldn't read any form of boot disk or a bios flash disk.
I sent it back to the supplier who sent it back ro Taiwan, believe it or not. (I would have thought it would have been cheaper to do a quick test then just replace the board)
I've got the board back now with a replaced BIOS chip but haven't fired it up yet.

This is the Compaq page (http://h10025.www1.hp.com/ewfrf/wc/document?product=92509&lc=en&cc=us&dlc=en&dest_page=product&docname=c00007682) you need to start at for downloading and flashing the bios, it gives you all the info you will need.

But I'd say try changing the CMOS battery first of all, and only then if it doesnt work go the bios flash way.

ok now i know its a abit bl30g motherboard

Unless you are reasonably experienced & are confident of flashing the BIOS successfully the better to do as others have said & take it back under warranty or to a reputable serviceman.
A failed BIOS flash will render it totally useless
