Hey guys,

Today I cleaned out my PC because my temps weren't looking so good. After I sprayed the dust out, I put my PC back together and when I powered it up, I immediately noticed a load whining sound coming from my PC - it kinda sounds like a continuous beeeeeeep. I put my ear to each part and noticed it was coming from my PSU and that the fan was not spinning (!)

I left the case cover off and powered my PC back up a couple more times; I noticed my PSU fan seems to move for a split second and then gives up. I then turned off my PC again, unplugged the power cord and held the power button down for 10 seconds -- The fan begins spinning on the next boot up and the whining sound was no more. But I turned off my PC again to check if the problem was gone, but the fan failed to spin on the next boot-up and thus the whining sound returns.

After a few more attempts I finally got my PC to boot up with the fan running, but there's a chirping sound from it every 10 seconds or so.

I'm aware that some models are set to not run their fan until you pull enough power, but that was never the case for my PSU. It always spun as soon as I booted my PC and the whining sound only occurs when my fan is unable to spin.

It is possible I over-spun the fan when I sprayed it with compressed air...? I honestly can't remember if I sprayed it for that long... but it might be possible I guess.

Anyway, can anyone help me towards a solution? It's almost like my fan is RNG based when I turn my PC on. Should I take the PSU apart? And what should I do inside it?

P.S. I can't replace the PSU at this moment.

Thank you!

EDIT: I rebooted my PC twice and my fan spun, but the second time (left my PC off for 2 mins for that attempt) there was a 1 second whining sound that faded away as the fan managed to start spinning.

Make sure you are using an insulated screwdriver! I should of mentioned to be very careful inside that PSU, it can carry a charge for a bit even after its unplugged. Just be careful. That being said, it really sounds like the bearings are going. Your fan will die. If your willing and safe, you can replace the PSU fan with a decent 140mm case or CPU fan with minimal hassle. It could cost under $10. You might have a fan lying around? Many people would advise you not to do this though but I could myself doing this, I like to frig with stuff. Anyway it should be a 2pin plug so be carefully if you try this and google PSU fan replacement. Or replace PSU.

Hey, thanks for the reply. I took my PC apart today and did what you suggested; I removed the wire frame and pushed down the fan. Unfortunately nothing had changed after I put it back together and turned it on. Well, except that the whining sound (when the PSU fan tries spinning) occurs when I reach the windows login screen, but I'm sure that's unrelated...

I recorded and uploaded a video of my problem:

It's a bit too long, so here are some time stamps:
00:00 - Power On
00:45 - PSU fan attempts to start spinning
01:10 - I manage to get it to start spinning by nudging it with a screw driver (lol)

And yeah, I know my PC is a mess. It's pretty old... but I cannot replace it at this moment. :/ I need it to last me another month or so at least.

Any other ideas? Or maybe I didn't push down on the fan properly?

Thank you.

Edit: one thing to note is that the fan doesn't always continue spinning after I nudge it. In that video it was my 4th attempt to finally get it started.

Thank you for your words; I will keep that in mind next time. Unfortunately I do not have an extra 140mm fan case or cpu fan, so I'm out of luck when it comes to trying to save it. And to be honest, I don't think I would want to replace the fan, anyway, because that PSU is almost 6 years old and another component in it could fail later.

I will just get a new 600w PSU in a month or so. However, if the fan in my current PSU doesn't last that long, I will downgrade to my old stock PSU & gfx card from 2010 (only 1 year of use, so they should still be good) for the time being.

Again, thanks again for your time!
