PC ASUS P5LD-VM repaired








This PC (ASUS P5LD2-VM/S) was brought to me and the complaint was the Motherboard was fully dead.

The lateral cover was dismantled (only two screws) to check on the inside especially the Motherboard.

First thing I saw in the Motherboard was the Onboard LED, so far everything was good.

Look at the extract of the User Manual of this Motherboard in the photo below.

First idea that came to my mind was to extract the RAM DDR2 module of the PCB to clean the golden contacts with my STAEDTLER eraser.

When it was cleaned and inserted into its slot, the PC was turned on, but there was no Video-out. Then other idea came to my mind (idea that has save me in some other occasions), to extract the Microprocessor for cleaning its golden contacts with the same STAEDTLER eraser.

When it was inserted into its LGA-775 slot and the PC was turned on, look at the photos below-see what happened then:

This time there was Video-out and the Motherboard was brought back to life. Mission accomplished.

    Good job, Humberto. I'm glad you didn't bend some pins on the microprocessor.

      Hi Robert. I´ve always been very careful in not bend any Microprocessors´pins. In this case the pins are located in the socket of the mobo. Thanks.

    Good job, Humberto. It's interesting to note that many times just the tools you need are the most simplest one: a prosaic brush and the notorius STAEDTLER eraser. And of course, the knowledge of the repairer.

      Hi Henrique J. G. Ulbrich, In my own opinion I think that the keys are the patience and experience of the repairer. Of course that any kind of tool used is an important factor too.
