New Video card worked fine but no display today!

[Method9]

I installed a new video card and it seemed to work perfectly a couple of days ago. I've turned the computer off and on a few times, ran a game, and used several other applications reliably.

Today I restarted the computer, but then there appeared to be no video output going into the monitor.

Computer:
Compaq Presario 6015US
AMD Athlon 1.47 Gig processor
2 X 512 MB PC2100 DDR2 RAM
integrated NVidia Geforce2 MX 32MB Video card
eBay special 650W power supply

Video Card:
ATI Radeon X1300 PRO 128 MB AGP

All the fans in the PC turn on and it seems to POST, but my monitor acts like it is still in standby mode. I ended up having to remove the card altogether and went back to using the integrated video card again until I sort this out.


So far I've tried swapping out the ram with some older ram, no success.

I tried removing and reinstalling the video card, no success.

I uninstalled the X1300 drivers (March 2009 version) and put the card back in, no success.

Any suggestions?

I'm going to look at the BIOS settings tomorrow, per the AMD support Website:

737-22472: How to Troubleshoot No Display on Re-start Issues

The following article provides explanations for no display on system restart issues and troubleshooting steps to resolve the issue.

Symptoms:

The user may experience no display from the monitor after installing an ATI graphics card when Windows has loaded or no display after restarting the computer.

The System may not post on a limited Power Supply unit.

Resolution:

Visually inspect the back of your computer's CPU for a monitor connector located within the section with ports such as the keyboard, mouse, and printer ports. If an additional monitor connector is found, the system is equipped with an integrated/onboard graphics controller. If the onboard video remains active with the Radeon card installed in the system, ensure that the BIOS is configured correctly for an add-in card. Since every BIOS is a little different, browse through the menus and look for an option similar to "Primary Display Adapter". The options should be any of the following: Auto, AGP, PCI-E, onboard, or PCI. If required, disable the onboard graphics adapter in the Windows device manager.
