I have a HP laptop that a few days ago suddently rebooted itself. When it did it came up with a black screen stating that my product information was invalid---"The following product information programmed into the system board is missing or invalid.....Enter to continue." I do that and it continues to boot the computer but I get asked to verify the version of windows I'm using. I do that and everything is OK until I reboot the computer and it starts all over again. I checked my BIOS and have found that the product serial is now set to 1234567890 NOT was is supposed to be with the computer. I cannot "get to" the serial area so I can reinput the correct info. I talked to HP and they told me to do a complete re-install of the system (wipe the hard drive) and start over. I got to thinking what good will a reinstall do if the BIOS remains "unrecognizable" I have done all the virus scans and systems scans that I know to do--everything "reports" fine. I am at the point of doing the wipe of the hard drive, but is it possible that will resolve the issue? Thanks for any advice or suggestions.
