well mine is a custom built PC by compaq but it has a model number (Compaq Presario 7000us), i already talked about some of this in the hardware section but obviously we needed a new thread for this...anyways i need to update my BIOS cause of some hard drive problems when installing a new OS...i already tried compaq support and downloads but nothing for my model, i also looked under BIOS screen (F10 when booting) and everyone says its under menu, but i dun see a damn thing, so pretty much i dont even know what my current bios version is...tried some utilities with no luck though
