Try unplugging components one by one (disk drive power, CD power, video cards, etc) with the system unplugged and see if the fan speeds up when you restart it. Note than when you remove certain cards, video for example, you may get beep codes. 

 

Everything in a slot on your PC shares a common power bus so any card installed may be pulling too much load on your power supply. Pull em one by one re-starting between each one.

 

If this doesn't locate the fault, check the power plugs to your disk/cd drives and ensure that you are getting 12VDC between the yellow and black wires and 5VDC between the red and black wires.  If you are not, and you have already pulled all cards/drives, you have either a defective power supply or your motherboard is drawing too much current.  In the last case, pull your memory cards one by one and re-start between each pull.

YOu will get memory size errors if you let the boot procedure go too far but all you want is for the fan to go.

 

You  can accurately pinpoint POST errors with a POST diagnostics board available at most PC shops. It comes with a code manual.

SOURCE: What lights should be on when the computer boot

You may possibly have a bad video card and a bad circuit on your motherboard. I would have the motherboard replaced. Some motherboards come with video cards, so once it is replaced, you may alerady have a new one with the motherboad part. If you not versed in doing this, you may want to get a professional to do so.

Make sure your fan is on high with the pull chain switch. Push the remote Hi button then pull the chain until it's on the high speed, Then DO NOT use the pull chain. Same with light , Push light button on remote then pull chain until it's on then leave the chain alone. If that doesn't do the trick then you probably need a new receiver.

Computer won't do anything, keyboard does not light up, screen is blank


So there is not so much as a BIOS message on screen? Any beeps?
If there is no life at all, you have a CPU/motherboard failure. This may be direct or indirect (e.g. no power to MoBo). Check your connections.
Otherwise, your boot device may not be operating. This is usually a dead or disconnected HDD. Check that it is plugged in. Does it get warm? Can you feel any vibrations from it? It should spin even if your cpu is dead but MoBo is alive.

Won't start but CPU fan vibrates but will not go full blast. Intermittant


It appears you have a faulty CPU fan and it is causing the CPU to overheat and shut down.
I suggest you replace the CPU fan. remove any dust from the heatsink and put new heatsink compound on the CPU/heatsink.

When I hit power button on computer, power light doesn't come on...and the fan kicks on, but nothing else happens. nothing shows up on monitor except the test screen with 3 colors...the computer doesn't...


THis sounds like a power supply issue.. I had a similar issue with mine. my fan would kick on for about 2 seconds then shut off.
Hope that helps

Casablanca fan speed problem


If this fan has a pullchain that also controls the fan speed, and you have a remote, the pullchain has to be set for the highest speed. If it is set at medium or low, it will mess with the remote operation. Note: usually high speed is the first pull after the "off" position.

KINGSTON VALUE RAM 1GB PC3200 MEMORY


Hi,
You have the answer in your question. I have checked the PC specification and you are right, it uses PC2700 memory. Therefore you need to install PC2700 memory. PC3200 memory will be the wrong speed and will not be supported.
