PC Makes a terrible grinding noise on start up, once running it's fine?

#1ValkassiumPosted 9/17/2013 3:09:46 AM(edited)
So if I put my PC to sleep, or shut it down completely, often when I try to turn it back on I get a horrible grinding noise as it comes to life.

Some times this stops, and it runs fine, other times, it'll blue-screen after 5 to 10 seconds. I've not experienced this before, and if I don't blue-screen after 10 seconds or so, the noise stops and my PC runs fine. Having Googled a little, it seems this may be my PSU? Is there any real way to fix this, or do I need to just buy a new PSU?

I know about coil whine, but this definitely sounds louder and more like a grinding sound, than regular coil whine.

I'm concerned every time I turn my PC off/on now as I know if the PSU blows it could take other components with it.

I doubt you can fix it if it's a PSU problem. No spare PSU's lying around? You tried cleaning the inside of the computer with compressed air?

I wouldn't think a case fan would cause me to blue-screen though?

And yeah, once my PC is running, it's silent. 100% completely silent. This is what makes me believe it's a bearing in a fan, it's just rattling/grinding when it first starts up as it's slow. Once it gets to speed it's fine.

My computer did the same sort of thing. Not too long after my HDD died.

Yeah I'm trying to work out if it is the HDD and not a fan. To me, the sound doesn't sound much like a fan, it sounds almost more electronic than mechanical.

I have difficulty with my hearing though, which is making it difficult for me to pinpoint the exact location of the sound, I may give it a try again tomorrow and see what's up.

I wouldn't have much of a problem if the HDD with my OS died, but I have a 2TB drive with ALL my Steam games on, would suck if that went.

So I tried again this morning, the sound appears to be coming from the MoBo. It's not a beep though. My front fan wasn't working, as indicated by my fan controller.

I disconnected the fan, re-started, the sound still occurred. Re-connect the fan and it now works again, the noise still happens though.

It's confusing me because the sound sounds mechanical, like a grinding, but it sounds as if to be made electronically. Rather than something like a fan grinding. I've check all the fans, my ram, hard-drives, CD-drive, graphics card. Nothing seems to be the source of this sound.

Sometimes it occurs once, sometimes 2 or 3 times upon start up. It lasts ~1 second each time.

Could you record the noise and upload it to youtube?

Not easily, no. Nothing I've found on Youtube thus far mimics the sound either. Like I say, it's definitely not MoBo beeps.

I'm randomly having trouble with one of my fans as well now. It appears to be spinning slower, and when I turn it down on my fan controller, it turns off completely. Normally, the fans would just power down to a slower speed and not turn off. I don't know if this is related though, because when I disconnected the troublesome fan, I still got the noise on start-up.

I feel for you TC. I'm sure i know the sound you are thinking of. Its kind of hard to describe and there isn't anything else quite like it.
