Has my hard disk failed or do I have another problem?

    I have a Sony desktop. I was trying out the Search and Recover program in what they call Strong Scan mode which takes a long time so I got on with doing something else while it was going through the process. When I got back the screen was frozen and I couldn't get any response at all. Eventually I switched off. When I came to switch on again I got a message on the monitor saying that there was no input signal and that the monitor was going into power safe mode. This is the only response I get each time I switch on.

    I suspected initially that the hard disk had failed as I have been suffering for some time recurring "boot disk failure" messages on startup as well as loud clicking noises. I read somewhere that this indicated the drive was failing? Fortunately I have been regularly backing up so it’s not the disaster it might have been.

    it has occurred to me that as I’m not technical I have no idea whether the message the monitor is displaying suggests another problem.Is the lack of input signal nothing to do with the operating system boot procedure and caused by something else?

    Before I do anything more I’d appreciate any input as I’d hate to change the hard disk to find that this wasn’t the problem at all.

    Any and all help gratefully received.

    Well I don't think its your hard drive, although you may indeed have problem there too. A hard drive that has quit should not stop POST, and you do not appear to be getting that.

    The most likely culprit at this stage is the power supply, and that could account for the previous hard drive error as well. Do you get any signs of life from the computer, any beeps or lights?

    Hi Triple6

    Thanks for the prompt reply. I don't undersatnd what you mean by "stop stop POST" but when I power on the power light shows up as normal and the fan starts to operate but there aren't the normal sounds associated with the operating system booting up.

    POST is the sequence the computer goes thru when you turn it on, its it bootup or startup procedure, and a hard drive that has failed should not stop the rest of the startup procedure to not occur meaning you should still see things on the screen and the system should beep its normal one beep.

    What can stop the computer from POSTing is any component that has severely failed, a bad or loose stick of memory, a loose of failed video card, a faulty motherboard, or a failed power supply.

    That's made it much clearer for me. I'm not getting a beep so does that suggest it's more likely to be another cause as you've outlined? I presume it's a case then of getting someone to test the components first before being concerned about the hard disk?

    You can simply disconnect the hard drive, its not required for the computer to turn on and work, its only there so that you can do something useful with the computer once its on.

    To figure whats wrong with the computer you, or someone for you, needs to reseat all cards in the computer and swap out or test the parts in the computer. If you are not comfortable doing that or have no parts to swap in then by all means have someone else do it for you.

    Again many thanks for your advice. I don't have parts so I reckon I'll have to rely on a.n.other.
