Hello Everybody, Sorry I Haven't Wrote In Awhile. I've Come Across A Very Serious Problem That I Need Help With. Briefly, I'm Running An Asus Motherboard, 3.0 Pentium Single Core, 3 Gigs Of Kingston Ram, Audigy 7.1 Sound Card, Ati 850x Video Card, Sony Dvd Burner, Sony Rom, Sony Floppy And Ahp Dvd External Copier Hooked Up By Usb. First Of All I Had Swapped The Video Cards Taking Out An Ati 1650 Pro And Putting In The 850x Card. I Dumped All The Drivers And Software On Both Computers First, Did The Swap And Reinstalled All Software. Both Systems Ran Perfect. Turned Them Off And Went On My Business. About 2 Weeks Later I Fired Up Both Systems And The Other System Now With The Ati 1650 Pro Works Perfectly, This System Now With The Ati 850x Came On And Suddenly Could Not See Any Optical Drives. The Bios Sees Them, But My Computer Doesn't!!!!! I've Updated Drivers, Uninstalled And Reinstalled Drivers, Gone Into Safe Mode.....no Change. The Hp Dvd Writer That Is Hooked Up To The Usb Can't Be Seen Either!!!!??? I Need Help Folks!!!!?????
