Need help locating problem on ASUS M2N-MX SE Plus

[digge]

Hi

I have this motherboard i have laying around that i swapped out cause it was acting up. Thought id build a surf machine for my mother. On to the issue im having.

The motherboard in question turns itself off. What i mean by that is that the machine completely dies, just as if someone forcibly turned the power off. It will work for a few minutes at best and just a few seconds at worst.

Have tried swapping out the PSU and stuff so i know the problem is with the motherboard.

Took it out and started probing around with my ESR meter to see if i could find something wrong. When measuring the 4 caps next to the PSU i get only resistance and no capacitance (measuring in circuit). Is this normal? i would think it should give me some capacitance even if the wrong one?

If you think its the caps can you help me identify make/model/uF rating so i can find a replacement.

In general, measuring any component in circuit is highly unreliable. The components may be in parallel or be affected by the surrounding circuit/other components.

For the board shutting down, try reseating and apply new thermal paste on the CPU. I had this once and I found out that the CPU was not seated properly. It helps if the BIOS can display CPU temperature or give an audible warning over a threshold as you can see/hear it quickly rise.
