Hi folks, As soon as I press the power button of my PC, it starts to create grinding sound noise during booting, but this kind of grinding noise vanishes within a minute. Can any expert explain this kind of weird problem & solution? Masud " I would like to get some help to discover the innovative world!"

It's most likely a fan going bad. Check it out and replace it before it stops and causes damage.

You are talking about which fan that i don't know; Thats all I have CPU & powersupply attached fan!!!! " I would like to get some help to discover the innovative world!"

Hello, I have a dell, it has two fans, one for the chip and the another for the tower/power supply, at first I thought my hard drive was making the noise, on opening I found the fan for the power supply/tower was making the noise. As you said it makes the noise on boot up and gradually goes away. I may replace it, but so far after start-up in does not make any noise and works well. I have had my old computer with fan noise and has worked for 2 years and is still going. That is probably what is making the noise and is easy to track down. hth

We don't know which fan either. You're the only one who can tell. Put your ear up to the machine, with the case open and you'll be able to tell fairly easily. If its the power supply fan, replace the power supply immediately. A faulty PSU can badly damage your system.

I am confused about the fan; would it be CPU fan or powersupply fan? Thanks for any help! " To achieve the knowledge about PC technology is the best idea in modern society and modern world!"

Yes, one or the other. I too had the same noise on a PC for 5 years before I replaced the PSU because I got tired of listening to the noise. Bryan
