I've had my Sony vaio (VGN-FW21M Vista Home Premium) for about 18 months now and never had a problem with it until yesterday. It was working fine all day but after leaving it idle for a couple of hours I came back to find that it wouldn't wake back up but it was very noisy (much louder than usual) like lots of programs were running however the screen remained blank so I had to force shutdown using the power button. Now every time I switch it on after getting past the vaio logo all I get is "operating system not found" and the hard drive makes a clicking sound. I've tried the hardware diagnostic hard disk repair and recovery tool on the recovery disc but there is no volume available to select and when i tried startup repair it says "no hard drive". I've checked the hard drive and it's in fine and the laptop has not been dropped or damaged in anyway
what do I do now?:sigh:
