Question Old motherboard won't boot.

[lantis3]

The PC was given to my brother in law but he already stopped using it years back and I took it back a few days ago.

INTEL DH67CF. The standby power indicator LED is on. (N)

No idea what's wrong. Hit the power button and "sometimes" the CPU fan will spin for a second then stop. No beep sound.

How do I know what's dead? PSU? CMOS battery? motherboard? CPU?

It is not worth spending too much time with it. Possibly try cleaning it, reseating all the components, put a new cmos battery in it and see what happens.

new carburetor?

jk i've a soft spot for old boards... what memory is it running?

Look for any bulging capacitors. Also any build up of dust that might have mold growing in it.

Most of the times I have seen the CPU Fan spin for a second and then die it has been an issue with the motherboard (bad caps etc...)

I have a Skylake HP desktop where the fans keep spinning but no display. Experienced that and any fix for it? It had been kept in storage at someone's place in a dusty corner and I used a 3M blower to clean out the dust before turning it on. It has been suggested that static electricity may have killed some component on the mobo. Any possibility of recovering from that?

Blowers are notorious for static electricity due to the air flowing over the blades / fins. I would never use a blower on electronic device. Example a helicopter generates a ton of static.

Board is probably bad.

When in doubt, minimum config. Unplug anything not needed to complete POST. Try again. If not successful, pull memory dimms and try again. This should at least give a POST error, typically some type of beeping pattern from the speaker (not speakers plugged into the audio port 😉 ). If no luck, next pull the GPU if it has one and test again. If you are working with nothing left on the board, and you're not getting POST errors, the mobo is likely toast. At this stage, you could always toss in a spare CPU if you have one just to make sure.
