W98 Operating System not found on dell 7500 laptop - Fan not working
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!
