Several possible sources of 'grinding' noise - especially if you've had your system a while.
- does it sound like a little plastic fan beating against a plastic frame (whirring sound?):Something lodged in the grill at the back of the system that got sucked into the fan. Power supplies are cheap if you need to just replace it.
- does it sound like a nail file scraping on the edge of the desk? (grinding like plastic teeth in a gear?): Check to see if your cd drawer is jammed (two CDs in it or one CD not lying flat in the drawer). There is usually a release hole in the front that a paperclip will work in.
- sound like "drdrdrdrdrdrdrdrdrdr...chhhhhh" and repeat over and over? Your main drive is crashing or partially crashed and the repeat is the drive re-seeking to find files. Back it up if you can and replace it. Sorry...
More info on what your doing when the sound starts will be more helpful.. let me know.
Just recently my computer compelety locks up after I hear some grinding noise from the CPU. I couldn't do anything but to reset the computer manually by pressing the button. Is the CPU overheating? Or is this a sign that the cpu is getting bad? This had never happened before. Please advise. Thanks.
