I might have not been really clear. Here is what I sent as a support ticket to XFX:
After receiving a faulty motherboard I had to wait before I could try my new GPU (XFX ATI Radeon HD 5850). I inserted the GPU in the PCIe slot and plugged in both 6-Pin power connector as stated in the installation guide. I then installed Windows 7, ATI Driver and ATI Catalyst Control Panel. I than installed StarCraft II and played for 15-30 min. Right after I was finished playing I shutdown the computer. A bit later that evening, when I booted my computer I wasn`t getting any signal from my GPU. I check my DVI cable, the 6-Pin connectors and check if the card was firmly in place but I still wasn`t getting any signal. I went ahead and placed the GPU aside to iliminate any chace of other problems. The computer booted just fine. As soon as I plug the GPU and DVI cable to it I don`t get a signal and can`t even get to the Bios menu. Am I doing something wrong, forgetting something or is there a problem with the GPU? Because it was working before I closed the computer. People suggested clearing the CMOS, could that work?
Thanks.
