I had a Windows XP machine that was going berserk.. freezing up.. not allowing malware scans.. I reformatted the disk and reinstalled the OS and ran through Microsoft Updates. Once I installed Security Essentials for Anti-Virus blocking it began to do the same stuff. This has lead me to believe that the machine may have a BIOS virus or at the very least the BIOS is corrupted. I am now attempting to see if I can flash the BIOS to try to fix. To do this for this particular machine I had to create a boot floppy as a MS-Dos startup disk. My problem is that when I attempt to unzip the bios update to the floppy disk I get this error: Can't create output file: A:\BIOSupdt.bat. Thanks in advance for any help.

a bad bios update could render the motherboard useless,only update bios if it fixes a known issue ,
did you check and make sure the computers fans was clean of dust and not just over heating ,also the hdd could be getting hot ,open case and feel aound for items overheating ,check video cards fan if you have a video card

My answers are my opinion only,usually

Are you following specific instructions for updating your BIOS...or just winging it?

If following instructions, please provide a link.

What makes you think that a BIOS update...is the correct step to take?

Here's link to the BIOS update instructions http://h10025.www1.hp.com/ewfrf/wc/softwareDownloadIndex?softwareitem=pv-8528-2&lc=en&dlc=en&cc=us&product=215492&sw_lang=&os=228&key=null&site=null

Decided to go in this direction as it was the only way I could find to remove a possible BIOS virus.

To open the computer case and check for hot items and dust, is there a particular way to go about this? However, I don't think its that though because I had ran it for several hours installing Microsoft Updates and then Security Essentials with no problems. The computer was off for several hours and then when I turned it on I noticed that Security Essentials was not started. I tried rebooting a couple times to see if it would fix and it began to go bezerk and freeze up as mentioned. Plus, I understand that anti-virus software getting disabled is a telltale sign of a virus, and since I had already tried disk reformat and OS clean install..

Hello I downloaded your file LOND312.EXE from HP's web site.

When you formatted the floppy disk in MS-DOS did you remove the files from the floppy before adding the files from LOND312.EXE?

Formatting a disk to be boot-able leaves other files on the disk, you need to remove those DOS related files from the floppy disk.

You may have to have XP setup to show hidden files and folders to see those files, if they are there, just delete them, do not format the disk.
