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

Ensure there is adequate power.
- 300 watts minimum for Radeon™ 9700/9800.
- 350 watts minimum for Radeon™ X800, X850, X1300, X1600 and X1650.
- Radeon™ X1800/ X1900/ X1950 require special power supply 450 Watt capacity with 30A on a +/- 12 volt rail (connection) minimum for single graphics configuration.
- 550 Watt capacity with 38A on a +/- 12 volt rail (connection) minimum for dual graphics cards configuration such as Crossfire. Please refer to the Crossfire section on the AMD website for more information.
- Radeon™ HD 2900/ HD 3800 and HD 4800 series are recommended to use certified power supplies.
- Verify that all required power connection cable(s) are connected to the graphics card from the power supply.
- Verify that the system have all the latest update files (service packs, patches) from Microsoft for the operating system, including the current DirectX runtimes.
- Set the memory settings to default values (i.e. DRAM Timing = SPD).
- Lower the memory frequency accordingly to the type of memory. For example lowering to 133/166MHZ for DDR2 memory (effectively DDR266/333MHZ).
- It is recommended that most current versions of the motherboard's chipset drivers (BIOS and CHIPSET) and the latest drivers for the video card are installed.
- Check that the card is firmly seated in the slot (PCI/AGP/PCI-Express), and clean away any dust in the slot or on the card.
- Verify that the processor and RAM are firmly seated - these components might have been displaced while installing the graphics card.
- Test system with a single memory module if multiples sticks are being used.
- Disable/Remove all non-essential hardware i.e. soundcard, network card, additional HDD etc.
- Make sure that the graphics card and the motherboard have the same AGP specifications. Please refer to Knowledge Base article 18872: ATI AGP Graphics Cards - AGP Compliance Details.
- Test the graphics card in another PC or another card graphics in the PC.
If the issue persists in another PC then the card is most likely defective. To request a warranty replacement fill out the warranty form.
