I have a PC with P4 630, 512MB RAM, GeForce 660GT etc. without a UPS or Floppy Drive. The problem is that my Samsung Octoedge SH-M522C Combo Drive is just not working after a power failure. It doesn't show up in My Computer and in Device Manager, its status is Windows cannot load the device driver for this hardware. The driver may be corrupted or missing. (Code 39) The troubleshooter doesn't help either and there are NO drivers on the Net. I have a driver CD but as my Cd drive's not working .... Help guys!!!
