One x PC with an Asus A7VBX-MXSE mobo. Four weeks ago the hard disk failed. Bios recognised it with the generic maxtor id, could not be detected in an external enclosure and would not boot. I swapped it out for what was the second hard drive in the machine, a Seagate. Yesterday, on boot up, the BIOS gave me the 'no system disc' error. I rebooted and Windows loaded successfully. Upon running Seatools the drive past the SMART test and failed the short diagnostic test. Now the drive is not recognised in the BIOS and cannot boot into Windows. I understand that this drive has gone belly up but my question is, what could be going on in the PC to cause two drives to fail in such quick succession? I am ready to put a new drive in, but don't want to fry another one!
Many thanks in advance.
