Remove the covers and blow the dust out. Use a laptop cooler to keep the temps down.

If checkdisk showed your drive as being OK and you don't have any viruses you need to use your laptop recovery disk.

Now my laptop is not even starting .. on startup after booting again n again using F2 n nw its hanging on the startup .. Thn taking me to startup repair after taking around 10 min.. At tht point its showing the blue windows screen with the mouse cursor rotating .. After 1 hr its shutting down again with no startup repair n then whole startup process repeating itself again n again ..

Use your Recovery Disk.

I dnt hv a recovery disk

Then you can't repair your laptop. You can take it to a shop and get them to repair it. Or you can buy another laptop.

You'll need to install windows.
