A very common fault on motherboards is on defect electrolytic capacitors.
In general the 1000uF capacitors used in power line filtering are dryied out or almost ready to blow.
By replacing them, the motherboard is functional again. 

Common faults for this problem are, random resets, not proper power-up or crashes.

Look for bulging tops or a dome on top of the cap. This is an indicator of incipient failure due to gas build-up inside the aluminum can. The electrical value of the cap has probably degraded far beyound the normal loose tolerances for an electrolytic cap. The indented lines on the top are to try to cause the can to fracture in a controlled way and split open the top of the cap instead of exploding the whole cap like a firecracker. In my experience this doesn't usually happen and the whole cap blows up with a loud bang and you smell that 'electrolytic cap death' smell.

I fully agree with pl4tonas, the most common reason for a failing motherboard is the electrolytic capacitors, normally the electrolytic capacitor close to the CPU and PSU fail earliest, but also other electrolytics on the motherboard use to fail.
Another thing to bear in mind when the electrolytic liquid comes out it can short or disturb some functions if it comes on the motherboard PCB, so make sure to clean thoroughly!
I have repaired motherboards with success and it's 95% a matter of just changing the electrolytic capacitors.
