Processor fan

[Brian]

Hello all. I have been working on a 6 year old computer trying to get win 98
up and running. Everything was working fine. I replaced the power supply and
had Win 98 working. Now the processor fan is not working and nothing comes on
when the computer boots. I have reseated the video card with no avail. Could
this be a motherboard issue ie motherboard battery or another issue?

If the CPU fan is not working, yet voltage is applied to the CPU, the CPU
will be fried in seconds. You need to first find out why the CPU fan is not
working. Perhaps no power is reaching the motherboard at all (hopefully).
Otherwise you probably have a bad motherboard and perhaps a bad CPU too. Use
a bare-bones test to check it out.

Bare-bones test:

Disconnect the computer power cable from the power supply.
Disconnect the monitor and any external speakers from the computer.
Disconnect the keyboard and mouse.
Open up the case and remove all add-on boards from the motherboard.
Remove all but one memory chip (unless you are using old SIMMS, which must
be installed in pairs).
Disconnect the power supply from the motherboard.
Disconnect flat-ribbon data and power cables from all storage devices ( hard
drives, cd-rom drives, floppy drives, etc.).
Disconnect all data cables from the motherboard.
Disconnect all computer case wires from the motherboard.
Make sure the CPU and CPU fan/heatsink are properly installed and the fan is
plugged into the motherboard.
Remove the motherboard from the case and sit it on a non-conducting surface.
Reinstall the video card onto the motherboard.
Plug in the power supply connector onto the motherboard.
Plug in the monitor into the video card.
Turn on the monitor.
Plug the power supply into a wall outlet.
Short across the motherboard power switch pins to turn the system on.

If the CPU fan does not begin to spin immediately, turn the system off at
once and try another fan.

Assuming the fan is running, then if you see the BIOS screen, your
motherboard, memory, CPU and video card are OK. If you don't, try another
video card. If that doesn't work, try another memory stick. If that doesn't
work, try another CPU. BUT don't do anything except turn it all off
immediately if the CPU fan is not running.

Good luck.

Check that the power selector switch on the back of the Power Supply Unit is in
the correct position (115v-230v).
Make sure the wall outlet is working properly.
A motherboard battery will not cause this.
Recheck that the power cord to the PSU is in properly.
You said the Processor Fan is not working when the computer boots?
Do you get any beeps?
Is the processor an Intel or an AMD?
What brand Motherboard? (some MB have a fail-safe feature that shuts off a
system if the cpu fan isn't up to speed)

So part of the jist of the message was to give the OP information on
what the BIOS beeps meant. Another part was to give the OP an idea of
what pattern to listen for. The BIOS isn't going to use Morse code in
a sentence for the error but rather a series of beeps with spaces. If
one knows there will be pauses and maybe long and short beeps then can
probably figure out what the computer is trying to tell him.
