"To protect your hardware from potential damage or causing a potential system lockup, the graphics processor has lowered its performance to a level that allows continued safe operations."
When I troubleshoot it says to see if the card has a suplimentary power cable connected, but mine hasn't got a socket for one.
It's a 6600GT Nvidia AGP card.
I was going to go down the route of replacing the PSU 1st as it's a 450W and it's the cheaper option to be honest!
Am I going down the right avenue?
