This is my first time posting. I just bought an ATI Radeon R4350 graphics card. I followed the (brief) installation instructions, but received "No signal" on two separate monitors, both of which had no problems previously. After reading some forums, I though I should disable the onboard graphics first, so I backtracked by removing the new graphics card and returning my monitors to their original ports. However, after returning to my original setup, I still got "No signal". I've already reset the BIOS, but still no results.
