1. Make sure that there are no other graphics cards or onboard graphics chips in your system. If possible, boot up in Safe Mode and then remove and reinstall the Detonator drivers.
2. Make sure that you have the latest motherboard drivers and BIOS. These can be obtained from your motherboard manufacturer.
3. Make sure that the AGP slot conforms to the AGP 2.0 specification, especially in terms of power coming through the AGP slot. Check with your motherboard manufacturer.
4. Disable sidebanding.
5. Are you overclocking either the Graphics Card or CPU? If you are, try resetting them back to their normal value, if it fixes the problem, you may need more cooling in your system.
6. Have you got an IRQ conflict with Graphics Card and another card in your system? The only device that can have the same IRQ is the 'IRQ Holder for PCI Steering'. If so, try assigning a different IRQ to that slot in the BIOS.
