I recently got my computer upgraded, Intel Pentium 4 2.81 GHz proc, ASUS mobo, gig of RAM, same power supply, same hard drive, same two cd/rw drives, 1 more case fan, and the same GeForce 6200 OC gfx card. The problem is once I got my computer back from the shop neither of my CD/RW drives worked. They opened fine, the lights lit up, but they don't register any disk at all, audio, game, or blank cd. Neither of the drive E or D show up in My Computer, Device Manager, or in my BIOS which is weird. Everything is connecting right I think, I've been tyring to find solutions on the internet, but haven't found anything on how to fix it. My floppy drive works and shows up in BIOS, as well as my hard drive, but neither of the disk drives do. I ran an aVast scan as well, just to be safe, and nothing showed up there. I don't know if it's the cables, or IDE controllers because I don't know much about that. I saw the other threads about this same problem sort of, but I don't know how to fix it. Any help here?
