Turned computer on, heard a pop and saw a flash. Hard drive can not be recognized even with an external power source. Blew out my hard drive, video card and power supply. All has been replaced, but would like referral to anyone who would like to try and retrieve the data on the bad hard drive. Can't afford to try the professionals. It's a Maxtor, 30GB, but very small amount of space used. Not sure what other info is needed for a reply. Thankx macoop
