ok, so im fixing my friends computer, and he told me that he couldnt install an os. i thought "wow, that sounds weird" so i asked him if i could check it out. i installed windows xp on it with absolutely not problems on an Asrock motherboard (which wasn't his motherboard) and then i swapped it out, and put his Asus P4C800 Deluxe in, and i tried installing windows xp, and it was doing great, until it started to register components. once it hits that point in the installation, the computer shuts off. when i turn it back on, it re starts the set up from where the last restart was during the installation. i tried installing win2k, and it did the exact same thing. it just shuts off when registering components. i havent tried booting with knoppix or anything to see if it works yet. but it has to be the motherboard. any ideas? im hoping it's something that can be changed with out needing to purchase a new motherboard. HELP!
