Gateway pc wont start up

Hi,

The power light on the monitor is what your refering to when you indicate it remains yellow?

This should indicate the monitor is getting power but no signal from the desktop.

What about any indication from the desktop itself?

The power and hard drive indicators on the desktop case show any lights ?

Any noise from the hard drive spooling up - any fan noise.

If there is indication from the desktop that it is actually starting up (by way of some noise) it may be the video card or on-board video that is the problem.

If there is no indication that the desktop is starting up, is it actually getting power?

Hope I can help further

cheers

First disconnect the reset switch at the front panel connections and see if it still is staying the same. It's not unknown for these to jam up and stop the computer booting as it is constantly in the reset state.

Troubleshooting 101

The first rule of troubleshooting a PC that will not boot is to reduce components to the fewest number possible.

Disconnect power and signal cables from all drives. Remove all cards except video card.

Try a boot. If successful, sequence components back one at a time.

If no luck, change out power supply. If still no luck, motherboard voltage regulation circuit has probably failed and mobo replacement is required.

To possibly save time, inspect mobo capacitors for signs of bulging or leakage. Tops should be flat and no leakage. Pay special attention to ones near CPU socket. If bulging or leakage is present, problem has been identified.
