Turn off the on-board video.

Install a different graphics card. If there are no display issues, then the graphics

card in question may be defective.

If your motherboard has on-board graphics capabilities, you may need to disable

them. Consult your motherboard documentation for more information.

Note:

Some manufacturers do not allow the on-board graphics to be disabled or to

become the secondary display.

: How to

Troubleshoot No Display on Re-start Issues

.

6.1.1.4  The computer does not boot up properly.

Verify that the installation instructions were followed correctly.
Make certain that the graphics card is properly connected to the power supply and

the motherboard.
For Windows® operating systems, restart your system in Safe Mode. Use Windows

Device Manager to remove any graphics driver entries under 

Display Adapters

 and

restart your system.
Check the system configuration utility for interrupt assignments.

6.1.1.5  During software installation on a Windows® OS, the screen goes blank.

The software is still installing. Wait 20–30 minutes to make sure the software has

finished installing and then restart the computer.

6.1.2  Troubleshooting AMD CrossFire™

The following are suggested solutions for common AMD CrossFire™ troubleshooting

issues.

6.1.2.1  Change Motherboard BIOS Settings

Some motherboards may have a system BIOS option to switch between single and dual

PCIe slot support. The default setting may be single slot support. Refer to the

motherboard’s manual for information to enable dual PCIe slot support.
For more information, see the AMD CrossFire Web page at 

http://game.amd.com/us-

en/crossfirex_about.aspx

.

6.1.2.2  Use Graphics Cards with Different Amounts of Memory

In some AMD CrossFire configurations, graphics cards with different amounts of

memory can by used; however, restarting your computer is required after enabling

AMD CrossFire. This will cause AMD CrossFire to reduce the amount of memory on

the card with the most amount of memory to match the memory size of the graphics

card with the least amount of memory.
Clicking 

OK

 to the memory mismatch error message will restart your computer.

Note:

When disabling AMD CrossFire you will be given the option to restart your

computer to restore the original graphics memory size or continue with the reduced

memory size.
