Ok first off I am new here. I got a custom built computer from my ex that he didnt give me any emergency disks for. About a month ago the computer got a missing or corrupt file message upon start up. I went out of town so I didnt mess with the computer till i got home. my friend sent me a disk to install the OS. Windows XP PRO. now the disk didnt boot up when i put it into the drive. so my friend had me open the pc up and look at the drives. my ex had 5 different drives hooked up into this computer. i pulled it all apart and tried the master drive in another system. it still read the same error. so my friend suggested putting the master drive in the othere system as my master in the system i was using. it would boot up and get to pci device listing. it read the master drive but not the cd drive. and then would stick on the pci device listing. i am not sure what to do. dont know if i hooked the drives back up correctly but i need help getting the system to work again.
