Motherboard fan dead

Lately I've been having problems such as monitor going blank (but pc still running) and blue screens with memory problems, as well as random resets. One thing I've noticed is the motherboard fan isn't running anymore. Most of these problems occur when I am playing games. If my screen goes blank, the fan I have on top of my processor also stops running. Sometimes if I turn it off and on I can get it running but other times I've had to wait a while before the PC starts up again with the processor fan running.

Currently I think the problem is the motherboard. Anyone care to give some input?

Jam it back in, in the dark.

I remember when my fan on my videocard went out. I got bluescreen all the damn time on games. If you wanna test this out, run your computer for a while, pop the case, and touch the motherboard. If it's the problem, it'll feel like it just came out of the oven =p

All the problems seem to tie into the mother board. I'd give it my vote of confidence, but don't act on just mine alone.

There's nowhere I can't reach.

If your motherboard fan isn't working, your motherboard will simply overheat and fail to run, so it's not surprising you're having problems. Can you maybe get a can of compressed air and clean it out and see if that helps it back to life? Otherwise you'll need to replace it. It's there for a reason, and should be spinning all the time.

This thing is sticky, and I don't like it. I don't appreciate it.

make sure cool all parts on pc.and must fans are working on video card,processor & power supply running 60 rpm will be good

I am a dolphin, do you want me on your body?

Fans running at 60RPM ISN'T good.

How ya doing, buddy?

Another thing you may want to look at is making sure the correct RAM is installed on your motherboard. I had the exact same problems after building my computer, but soon realized I had one stick of RAM in there for a computer that was built to use dual RAM.

Once I put in the dual 512mb sticks, it's been running smooth and stable ever since.

What kind of toxic man-thing is happening now?

Yeah...60RPM's means one revolution per second...which means very very slow.

FELIPE NO

Sounds more like a power supply problem than a motherboard problem. Any idea of the wattage rating and make of your PSU?

Just replace your mobo fan anyways. Make sure that the fan is able to handle your cpu speed. Meh, replacing the fan is cheap and won't hurt anyways. Cheaper than replacing your cpu or mobo.

Replacing the motherboard's fan won't solve the issue. The CPU's fan is also crapping out so it's either the motherboard or the power supply that need to be changed (or both). Only thing to do is swap one out and test it.

The DIRECT problem is overheating. The indirect problem is whatever's causing the overhead. If it's just dead fans you're lucky - they're easy to replace. In the case of the Northbridge fan, you can often replace it with a heatsink instead of an active fan - that's what I did. For the CPU HSF, You'll have to clean it out. If it's power problems, however, you'll have to replace the PSU - not an overly complex problem, but in tighter cases it can be annoying as hell.

Thanks for all your input. Upon further investigation I found that the psu power connector to the motherboard has a burnt pin/connector. So i'm not sure if it's the motherboard or the psu that needs replacing, probably both though.
