I recently got asked to build a computer for someone, i tried installing the OS onto it the first time it failed saying that some file it needed to install was missing. I tried again and this time it went through but after it had finished installing it kept having hangups and freezing. I decided to try another time to install the OS onto it and it finished, but now the dvd read function of the cd/dvd drive is not working ... What I am wondering is if the SATA drive is the problem because I normally would be installing onto IDE hard drives. The board is an ECS Elitegroup P4M900T-M, and the hard drive is a Samsung 250 GB 3gb/s. Another thing once the computer has fully booted up, the hard drive is showing as a removable drive , i am just wondering if it is supposed to be showing as such. Thanks for the help in advance.
