PC has no video

July 19, 2013 at 05:47:28
Specs: Windows Vista
The Gateway GT5622 does not come on the monitor. There is a blue light on the desktop indicating it is getting power. I am wondering if the video has gone bad on the motherboard? I plugged the PC into two monitors--one that I know works.

Being that it's a Gateway, I suspect the power supply is bad. The blue light isn't an indicator that the power supply is good, it just means that it's putting out enough power to light up the blue light. Do you hear the fans spinning up? The HDD crunching away? Any beeps from the motherboard?

Hi Seminary,

As you mentioned that you have tried good known monitors, it can be an issue with the desktop tower.

Did you perform any recent hardware change?

If there is a PCI Express card installed on the system. Remove it and try connecting the monitor to the integrated Video port.

NOTE: Internal components are to be disassembled by a professional only.

Thanks & Regards

The fan on the Power Supply and the fan attached to the motherboard are both working. Replaced the Power Supply and it is still not giving me anything on the monitor.

There is no PCI express installed. There is a PCI Modem, but it appears to have been installed a long time.

I used to be a full time professional application programmer that fixed computers. It has been three years since I have worked in that field, so my trouble shooting is a little rusty.

"The fan on the Power Supply and the fan attached to the motherboard are both working"

OK, are there any beeps coming from the motherboard or case speaker? Try removing all the RAM, then try to boot. You should get beeps without RAM.

"Replaced the Power Supply"

Please post the make/model/wattage of both the old PSU & the replacement.

Hi Seminary,

If using a different memory does not help, system board needs replacement to isolate the issue.
