    We need to know more about your machine, What is the new Graphics Card model? What kind of power supply do you have and how many watts does it put out? What type of processor do you have?

    Are you running Vista or Windows 7 by any chance? It sounds similar to the atikmdag.sys/TRD issue.

    That said, more info on your system would be useful. Processor type, motherboard, Windows version (including service pack level), graphics adapter & driver for starters.

    well its simple really :) you just look at the back of your PC and, there it is. At worst its printed inside the case on the CPU.

    I've been looking into the atikmdag.sys issue as I've been having it on my home system since I installed Windows 7. I originally had a fairly old card (Powercolor Radeon 9600 Pro) that had the problem and assumed it was a driver issue, but I recently chucked in a Sapphire Radeon HD 3450 and the exact same issue happens. There seem to be a few variations on the problem, enough to suggest it's not just one fudged driver but a problem with how the Vista/Win7 OS interacts with the display driver, probably compounded by less-than-stellar driver quality as Win7 is only recently out.

    Which is a long way of saying there's no one guaranteed fix.

    You'll probably have to take the case off your PC to find out the power supply details - it's the box where your power lead is connected. You should have a manufacturer name and model number, along with a power rating in Watts written in there. The documentation for your card should specify the minimum power rating required for your graphics card, so check that and compare it to your actual power supply rating. I don't think power is going to be the issue here but it might be contributing.
