Question about Dell Dimension 5100 (D51L1) PC Desktop
Computer had a pwer blip and will not re-start. Green light in the computer by power supply is ON. No lights on front of panel. Their is power to computer. Power ON button has no response.
If the power button on the front of the tower has no indications, then you most likely have a failure of the power supply.
Open the tower, and inspect for burnt wires. If you find no burnt wires, remove all PCI expansion card and all external connections, then connect the power cord and try to turn on. If no power, then you will most likely need to replace the power supply.
It is the least expensive part to replace on a no power situation. If replacing the power supply fails, then the front IO panel (Power button board) is next, then the motherboard is the 3rd most likely part that may have failed.
