Computer help
For a last few days my Computer has been making a loud noise..........sounds like a grinding noise........and it starts up at random forcing me to shut off the computer.......when I restart it after a while the noise is gone and things run normally.......but then the noise starts up again..........sometimes in hours....sometimes the next day............while the noise is up.....the Computer works fine....no lagging....no freezing......just the noise........I checked my performance while this was happening and CPU and RAM seem to be functioning normally.....as far as I can tell.........noise also starts up when the Computer is asleep.
Another point to mention would be the little red light on the front of the CPU.......the 1 that's always flashing......when the noise starts up that light doesn't flash anymore just stays a solid red. I've been reading online about this and a lot of people say it could be the hard drive........what do you guys think.........could it be the hard drive even though it functions normally when the noise is going on.......and also when the Computer is asleep....during which time I assume the hard drive is shut down. Could it be a fan issue.......personally I think it is the fan inside the power box..........that's where the noise seems to be coming from. All this started last week when I had my Computer off for almost 2 days.......usually I never shut it down.....just put it to sleep.......could that have something to do with it? I've talked to my Computer guy......but since the noise starts up at random and often goes away when I shut down and start again there is no way for me to show him the problem. Any help appreciated. |

It could be an issue with the PSU, would you describe the sound as clicking?

Well, it is obviously an issue with one of the two moving parts within your machine: either the HDD or the Fan.
As a precautionary measure I would advise cloning your hard drive onto an external drive. I would then open up the casing of your computer and start it up. When the clicking begins, disconnect the fan. If the clicking stops it means you have a problem with your fan, if it does not, then it is a hard drive problem. In the first case, simply replace the fan, in the second case replace the hard drive and then copy over the clone you made from the external drive. Best of luck!!

In many cases a grinding noise is associated with a fan. From what you describe it could be the power supply's fan. With the computer shut off use a vacuum cleaner to suck out as much static debri (dust) as you can from the openings for the power supply fan. While your at it open up the box and also vacuum out any static debri (dust) that may be inside. If a grinding sound continues or gets worse then it could be the power supply or cpu. A HD may only emit a grinding sould when written to, however that would be very rare and Windows would give you a warning during boot the HD failure is about to occur.

Along those same lines, when your computer is up and running and starts making noise, put your hand in front of the main air vent. If you feel no air coming out, it's likely the fan. Eyeballing it with a flashlight should confirm this. (Always wise to have a can of compressed air handy, and shoot some in all vents and in the keyboard at least once a month.) Also, it wouldn't hurt to add a temperature sensor program like CoreTemp, just to see how hot your computer is running. If the temp spikes when the noise comes back, it's probably the fan. Tough to pinpoint what a "normal" temperature should be... for example, my laptop runs anywhere between 25C-60C, depending upon how much CPU power is being used, but gamers will tell you that they can run upwards of 80C-85C without issues. |

I've heard of "clicking" noises from hard drives - but never "grinding". If it is a really loud grinding sound then my bet is the main fan. I had that problem on my old PC. Just as you described it would come and go at random. I took the cover off and found that if I gave the fan a quick prod with my finger (it's not powerful enough to hurt) when it was making the noise, the noise would stop - well for a while anyway. I lived with it like that for about 6 months - I was too cheap to buy another fan.
I think it is just the bearings in your fan wearing out. |

The air flow from the power box fan is significantly less when the noise is up......however the fan is still spinning. As for cleaning, I've already cleaned out everything, so I don't think it's a dust issue. I added a temperature sensor last week.....but I have yet to check if the temperature spikes when the sound is up.........my normal seems to be around 50C. |

I suggest you check out forums that discuss your computer model before any attempt: better safe than sorry!
