hey guys, my window suddenly doesnt turn on as usual from yesterday, it is a second hand, model Dell, when I plug the power cable in, the fan in about 10 second moves extremely fast, and the window doesnt show up, it is no sound at all, so i dont know what the symtom is. I looked at the mobo, it has light, i also take ram, CPU, fan, some cables out and then put in again but nothing changes.

i believe it is the BIOS problem, so what STEP do i need to take in order to solve this problem, thank youDear Johnha169,
What model of Dell is it? just so we have some idea of what the SPECS are and if there was any common issues.. By you saying there is no sound at all, do you mean it doesn't even POST to bios screen? or does the Dell logo come up but it won't BOOT into windows? Hey, thx for ya prompt response, I am unsure what model it is, but it is pretty old, pentium 4.

I think it doesnt even post to bios screen, so it is blank screenDo you see any diagnostic lights from behind the tower? If yes, can you describe what lights are turned on?well, it only has the BIOS light on, yellow color, but forget this because it suddenly turn on again and saying no boot device

So in short, I found out it is my hard drive problem.

The question is how i can RESTORE my file data in hard drive while my hard drive is not recognise. thanksHere's One Method...

The HDD does not need to be bootable to do this.If given the time also, see other troubleshooting steps for No Boot Device.
