|My HDD has stopped being detected.|
I have very recently replaced my CPU (The old one was burned and no longer worked) and bought a new chunky heatsink.
When my PC was reassembled I made sure everything was plugged in. New SATA cables came with a new motherboard (Not installed in this PC) which I decided to use for my HDD and DVD-ROM. They have handy clips so the cables do not slide out.
I used these cables to elimate the possibility of a faulty connection.
When I powered on the PC, POST test was performed and then it moved to the BIOS, which asked for the 'System CD' to be inserted. The DVD-ROM is set as the secondary boot device, and I found that my HDD was not being detected.
When I attempt to insert the system CD and perform a Windows System Repair, it demands for a disk to be inserted into a floppy drive which the PC doesn't have.
IDE HDD Auto-Detection on all channels could not detect the HDD.
IDE Channel Master / Slave and 'Access Mode' are set to Auto.
The HDD has been with us since we bought the computer, so it's about 2 years old.
