yesterday, my AMD FX55 and matching Gigabyte motherboard and ram came in through Fedex. i had planned on upgrading my system from my athlong 2600+. at first, i tried just putting first hard drive in to see if i could just re-register as i had done before. however, whenever it gave me the registration option, the whole computer froze before it could load my background and i had to restart. at points, the computer beeped and restarted on its own. no biggie, i thought. i'll just install windows on my second hard drive and go from there. i put windows 98 on my drive (although i had several errors and made a few attempts...every time i started it at last, windows explorer had and error and made me restart just to do it again). but at one point i was quick enough to get the XP Pro setup going. i tried a clean install at first, but a few files couldn't be copied from my cd. bummer. so then i tried the upgrade. that had errors several time and froze completely a few minutes ago. now, i'm getting an error that C:windows\system32\config\windows is missing. it says i should be able to repair it from my cd, but no such luck as i can't really boot from that cd. so, whatcha think? could my hard drive be going, maybe? i'm not sure how i've gotten so many errors. both discs are scratched, but not that badly. and what do you think would make my system keep restarting with the first hard drive. couldn't be overheating, do you think?
