Hello guys,

I have Dell Inspirion 7500 laptop with W98 which is very old. Suddenly I got a black screen w/operating system not found. When I rebooted it's making a loud buzzing sound and at times when rebooting on several occasions I get two different messages 1. operating system not found and 2. pc unexpectedly shutdown due to hardware/software problems do you want to start in safe mode, safe mode w/networkng etc. I thought it might be a HD problem but when I inspected the laptop the fan is not working! Could this be the problem. Please let me know what I can do. Much appreciated!

    Accepted Solution

    It could be overheating.
    I would suggest removing the hard drive and using either a USB to 2.5"" IDE converter to access the data, or getting a 2.5" to 3.5" IDE  adapater so that you can plug it in to any desktop as a slave drive ( instead of a CDROM or jumper as slave )

    I would also download the Maint. manual from Dell and see if you want to open it up and try to replace/ clean the fan.

    I hope this helps !

    Yes. As SysExpert said, overheating of a CPU can gives scores of error messages. Replacing the system fan will bring the system back to working condition.

    as said, first get the fans working.
    then you can test the disk by booting from the ubcd, and select the correct disk diag :

    "Very old" laptops aren't always depending on the fan for normal operation. What you hear at bootup is probably initial spin-up of a fan with bad bearings, so the cooling issue should of course be investigated, but it is by no means certain that the fan should be running all the time. Lubricating the bearings could be a good thing.

    As suggested above, check the hard drive.

    If you need data off the drive and it still spins, you might want to try the refridgeration/ freeze method, and use an adapter ( either USB or IDE ) to try to get data off.

    good Luck
