CPU overheating? Please help!

by nivlac79 / November 15, 2004 12:31 PM PST

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.

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.

Hi there, thank-you for the quick response. I think I have found the problem. I first opened up the computer case and hit the power cords/connectors (4 pin molex) a few times, it made the computer freeze (after the same noise). And I already knew it had something to do with either the PSU or maybe just bad power cords/connectors. I have a 400W PSU, and I have put in a heck load of stuff after I got the computer a few months ago. I have two 5.25 drives (one dvd/cd-rw combo, one dvd burner); two hard drives; one 5.25 temperture/fan control unit; two 80mmx80mm square led fans; three 12 inch neon/UV lights; one 9800 pro video card; and the cpu/motherboard of course, all running off from this 400W PSU. And I just dont think its enough anymore after I installed the temp/fan control unit two weeks ago. I unplugged the temp/fan control unit, ran a few programs, and havent had a lock up problem again yet. I will give it another day or so then will look for a higher power PSU online.

Thank-you for your help.

The Samsung RF23M8090SG

One of the best French door fridges we've tested

A good-looking fridge with useful features like an auto-filling water pitcher and a temperature-adjustable "FlexZone" drawer. It was a near-flawless performer in our cooling tests.
