I've seen this problem come up time and again and I was wondering whether there is a different approach to it. Yesterday I bought and installed a new graphics card in an attempt to moderately upgrade my PC. The new card is an ASUS built ATI HD 5450 (the precise model is Asus 5450 Silent). Everything is all fine and well until I start playing a game, any game at all. The screen starts distorting and flickering uncontrollably making it impossible to play a game. I tried uninstalling and reinstalling the 10.6 drivers (didn't work) I checked for a missed power supply to the card (there is no external power supply to it) and then I tried down-clocking the card. I had read that a simple reduction of 25 Mhz should work (the memory is clocked at 800 so I tried 775) but I had to reduce both GPU clock AND Memory to 500 MhZ (via Catalyst Manager) for this to work. After the down clocking everything works fine but I didn't pay for a 500 MHz clocked card!! Is there anything I'm missing here or should I return the card back?
I'm writing this from the office so I don't remember my PC stats but I do have a 650W PSU so that shouldn't be an issue.
