COMPAQ CPU Motherboard Repaired
A CPU with Motherboard COMPAQ EVO D510 CMT was brought to me from a co-worker because the Operating System was working unstable and it was restarting most of the time. I realized that two main reasons could be causing this faulty:
- The Operating System.
- A hardware trouble.
First of all I did a quick check at simple sight, and then I decided to open the chassis up to look if there was any bad/burnt component, bulged electrolytic capacitor, circuitry damage, etc. When I saw inside there were eleven bulged electrolytic capacitors (2200µF/6.3v) so they had to be replaced anyway to save the Motherboard.
Obviously, the eleven e-caps had to be substituted with similar ones.
It was a little difficult to change that amount of capacitors, but it was not anything impossible at all.
When job was concluded, a SMPS was connected to Motherboard such as a keyboard, a mouse and Monitor on the workbench. The SMPS was switched-ON and there was display.
Then the Motherboard was inserted into the chassis and all connections were done, and I felt very happy for my co-worker because the Operating System has been working perfectly since that day.
