PC won't shutdown / fan problems

[xhazy]

I have 2 problems that have started occurring out of the blue.

1) My computer won't shutdown, it just hangs on the "shutting down" screen until I manually turn it off with the power button

2) When I start up my computer one of my fans get much louder than normal, sometimes it goes back to normal after awhile. It seems like it's getting stuck on something but there's nothing in the way and I've cleaned it out. It doesn't stop or anything.

Can anyone help?

1) - often a driver problem. does it shut down from safe mode?

2) - possible bearing failure. How old is it?

Is it made by Toyota?

I seem to have solved the first problem, but not sure on the 2nd one still. It's about 1 year old.

If nothing is obstructing the fan and it is not out of balance from dirt, I imagine the noise is the bearing.

What was the other fix?

Lots of time when you 1st boot up the pc, some fans (specifically the cpu and vga fan) will spin up at max speed, and then slow down after the OS takes control.

I can't really say exactly why, just that this is very common among PC's for whatever reason.

I'm guessing when you say louder than normal, you mean the fan is louder? I take this to mean the fan is louder due to higher RPM as opposed to being louder due to bearing noise.

If the fan is spinning at higher RPM, its going to be louder whether it has noisy bearings or not.

Also, I had a pc in the past that didn't shut down and I downgraded the bios (there were only 2 for the motherboard and I had the newer one and switched back to the older one) and then the pc started shutting down normally. Must have been some bios problem that caused it to not shutdown.

Also, which fan is the bad one, xhazy? Maybe you should replace the fan, especially if its only a case fan.
