Until you get this working, I doubt that you'll be able to access the on-board
monitoring chip...
Is there an area in the BIOS where you can see the monitoring chip results?
Perhaps it will display the voltages and CPU temperatures? While you are in
the BIOS, look for something that might be disabling the on-board SMBus or
sensors.
See my answer to your question below for more information.

Some motherboards have sensor chips on the ISA bus. Yours doesn't (based on
what we see below) so you don't need to do this in the future...

That's just wrong and probably caused by the broken loading of i2c-elv.

This strongly suggests that you NOT load the elv driver. You don't have one
of these interfaces on the board and it's causing you problems.
rmmod i2c-elv
and don't probe for it again.

There are three possible reasons:
1. Your motherboard really doesn't have it. In which case you probably don't
have any sensors.
2. The BIOS hasn't enabled it. It doesn't show up in your LSPCI output. I
expect you should be looking for a device with PCI ID 2483. It will be on PCI
BUS 0. The other devices are there (2482, 2484, 2487, 2480, 248b) so perhaps
the BIOS has disabled it.

3. Your motherboard is broken. The chip is faulty and the SMBus function is
not working. If you get voltages, temperatures and fan speeds in the BIOS,
that would elminate this cause.
