I was on my desktop yesterday and shut it down in the normal manner and then later on in the day went to go back on it and it came up with the screen that the computer did not shut down properly - did I want to start normally, start in safe mode etc I pressed to start normal it went to boot ini screen and my computer is making a grating noise and then it goes back to the same screen that the computer did not shut down properly and I cannot seem to get it to do anything else - does anyone please have any suggestions as to what can be wrong. Thanks Kim
