Hey all. Stupidly I know, I bought an HP from Bestbuy about a year ago, mainly for my wife. Now I'm gettin a BIOS rom checksum error. Now, thanks to the great 'ol HP, and bestbuy who doesn't carry system disks as HP won't allow them to, I'm stuck with a busted HP. I've already tried replacing the BIOS, tried replacing the memory, still nothing. HP won't give me a System disk despite repeaded calls, emails, etc. So I figure I'll just replace the motherboard. Just need a bit of help though. I've found a motherboard that'll fit all of my hardware, and my processor. Will I have to put on a new OS though? A friend of mine told me I would, but I wouldn't think so as the OS is held on the Harddrive. I figure new MB and just switch over all my internal's will fix the problem, and for a heck of a lot cheaper than what HP want's me to pay. Anyone think that's a good idea? Comments, suggestions, etc. PLEASE.
