I need computer help?

I have a problem with my disk drive. I have successfully burned cds and dvds on my tower, however it will not read any of my Windows 7 disks which all work, I have my computer set to boot from cd/dvd but when it gets to that point it just sits idle, the HDD light and the light on the drive blink in unison and the drive does not spin up the disk. I know it's not the drive as I have swapped it out for 2 other working drives and get the same result. I was going to uninstall the drive and reinstall it but if it won't work with 2 other working drives then the drivers aren't the issue either as Windows 7 automatically installs drivers for any drive detected even without internet. This is a huge issue as I am looking to do a full wipe of my system so I can network my 2 computers as I have also been having problems with my homegroup not sharing files from one computer to the other. I can install Windows 7 via USB only if I boot Windows first and start the install right from my desktop even if I set it to boot from USB. Any help would be greatly appreciated.
