[SOLVED] Fan spinninh slow and making loud noise

[Kromehearts]

Sometimes when I turn my pc off for the night, or off for just an hour my pc fan slows and makes a loud annoying sound. Not everytime but just sometimes. I fix it by spinning the fan with my finger then turning it back on. Anyone know the problem and how to fix it? I was thinking it was a connection error but it works again after I spin it with my finger.

Its not a pre-built but I got it built by microcenter.

Any warranty left?

If so, take the pc back to Microcenter.

Otherwise anything you do may void the warranty.

No warranty left?

Update your post to include full system specs and OS information .

How old is the system?

From what I could see the system appears fairly clean.

That said: power down, unplug, open the case.,

Clean out dust and debris.

Re-seat, by sight and feel, all connectors, cards, RAM, and jumpers to ensure that all are fully and firmly in place.,
