  1. Sounds like something is going on in the back ground your not aware of. System possibly doing a virus scan? :s

    Maybe. I have avast installed but it i think it is not doing any thing.
  3. I would give the system a reboot - if you have checked the processes (ctrl+alt+del), and there is no CPU usage going OTT or unwanted program running, disk trying to be read in the dvd drive, no virus software running (which you would notice in process anyway). Plus! What ever your running on the pc at the time, I.e. game causing it to go crazy. So Yeh, give the pc a restart.

    If that don't work, pass it on too the experts :)

    It happens even after restarting. I have another os installed but the same problem occurs there. What should I do now ?

    Since it happens on both OSs (dual boot?), I think it's probably your hard drive going bad, and trying to recover itself (and failing). Run a check-disk utility to see if you have lots of bad sectors.

    With the PC booted, unlpug the HDD and see if the light still blinks. (I know, kinda stupid to check the HDD LED if no HDD.)

    Is your anti-virus up to date? Run a full system scan, and see if it finds anything.

    Do you have Windows Defender? It may be running too.

    Check what services are running on boot up (services.msc).
