hi -- i'm trying to fix my parents' pc (a gateway 507gr) which has been really unstable & unreliable for a few months. windows wouldn't boot properly, windows reinstalls wouldn't work. it'd boot into the bios ok, but that was about it. in desperation yesterday, i decided to upgrade the bios, hoping to have a good foundation for reinstalling other stuff. i downloaded the files from intel's site (the board's a d915gag, with a p4 processor with hyperthreading), and did exactly what it said. now things are far worse than before. intel gave several sets of directions for flashing the bios. the least invasive was to make a cd with this bootable .iso file, put it in the cd drive of the target pc, and boot it up. it did boot under that scenario, but instead of anything resembling the screenshots they showed in the instructions, it said something about the old bios id number, the new bios having a different number, and trying to install it, and then it went immediately to a c: prompt. for a few moments, the pc made these really quiet noises -- not hd sounds, but something somewhat similar (almost like sci-fi "electronic" sounds), but nothing ever happened. it wouldn't even boot into the bios after that. another method intel gave for flashing was to download & copy this .bio file to a cd, put in into the drive of the target machine, and boot it up with the bios configuration jumper off, to force it into recovery mode. it was odd that the instructions didn't say anything at all about the cd needing to be bootable in this case. this didn't work at all, and all the computer displays at this point is either the "gateway" splash screen and then another, completely blank screen, or else it shows only the "no signal" monitor icon. the power button on the front of the case doesn't work now, either. turning it on & off is now just by plugging/pulling the cord in back. can it be recovered from this, or is this pc utterly ruined? their instructions were, apparently, awful. this pc has no floppy drive, and now there's no os, no bios, and i have no idea what else to do. i'd appreciate any help anyone could offer. thanks.
