Thank you guys for all your help I've managed to get a lot of problems fixed and learned a lot from all of you. Unfortunately I still have some problems, I have managed to make the computer work! yay! I purchased a 500W power supply and it just worked like magic.. I now have a SATA 250GB Hard drive also, so I don't have to worry about IDE devices other than my cd drive, I have a dvd drive but for some reason the cd holder won't eject out so i had to use my cd-drive. But i did boot it up, and now it says "Reboot and Select proper Boot device or Insert Boot Media in selected Boot device and press a key" which is driving me crazy. The first thing I see is 3 options 1. Press F2 to go into setup 2. Press F11 to go to boot menu 3. Press..something else i forget, to switch screens... I have gone into setup many times, and tried to boot from CD and i dont really no what to do.. Any help? I have a CD that came with the motherboard, so i tried that.. and I also tried using my Windows 7 Installer CD to install windows, but its the same. Is it because Im using a CD-Drive instead of a DVD?? Help?
