Gigabyte GA-H61M-DS2 will be restarted several times after being triggered before it can be lit for repair

Gigabyte GA-H61M-DS2 will restart several times after being triggered, and then it will light up. Remove the R220 and replace it with a new one. The machine will light up directly, and the fault will be removed.

Machine model: Gigabyte GA-H61M-DS2 RVE3.0

Symptom: After triggering, it will restart several times before being lit

Maintenance process: after getting the machine for measurement, it is found that it can be normally lit after being triggered and restarted several times. After pressing the restart key, it can be lit after being restarted several times.

Because I was a novice, I only looked at the approximate voltage when measuring the voltage. I didn’t look at the specific voltage. I made a mistake. I looked at the circuit diagram later and measured the voltage step by step. I found that the voltage of the three pins of Q24 was 2.4V (actually 1.8V). After finding the problem, I measured the voltage of the three pins of U3A was also 2.4V, which was not equivalent to 2_ 5LEVEL came directly. It was judged that there was a problem with the resistance R220. The resistance value was only A Ω when it was removed. It was determined to remove one from the feeding plate and replace it with another one, install the U plug memory, start the machine, and light it up directly. Pressing restart will not restart it repeatedly. The problem solving and maintenance is over!
