This is my first time posting on any forum, so please excuse me if I miss some things out. I recently got a second hand EVGA GTX 460 1gb OC from an online auction site. I have a Dell XPS 420 which had a 425w psu in it. I installed the card and attached both 6pin power cables and I got a single beep, no signal and my computer wouldn't boot into the operating system. I figured this might be due to my power supply being under the recommended wattage so I bought a Zippy 600w psu and I'm still having the same problem. My old card still works fine, so no problem with the motherboard. I've tried uninstalling the old gpu drivers and still nothing. The error code that my computers lights display translates to "Other failure" which according to dell means there is most likely a hardware failure. Is this a common problem and is there a solution? or am I now the proud owner of a $230 paperweight. Thanks in advance. Nesh.
