Just installed a Radeon HD5750 into my Gigabyte GA-K8N Pro board. When I power up the system, there is no bios beep and no boot or acces to bios. Running only one card installed in PCIE slot 1. Not running in SLI mode. 4GB of RAM currently. Any suggestions?

What's your power supply? Did you plug in the 6-pin PCI-E connector?
