hello i have bought a semi-new system with an old acer power f6 motherboard. i have the latest bios file, but cannot find how to update it. when installing a fresh copy of windows xp it seems to run ok, until the first reset. upon reset, i get error loading operating system message on a black screen. the hard disk is 250gb sata. can anybody help? i looked to update the bios, but cannot find any instructions of how to do this - it appears i need a functioning operating system and can't update it without windows running. possibly a function key needs pressing on boot? note the bios currently installed is not the latest version. i ran a full disk format - not quick - during setup. tanks for any advice.
