So i pulled the gt 220 out of one of my pc's because i wanted to put it with another pc because it's the best gpu i have at the moment and i installed the gt 220 in my i3 system and it worked fine with the drivers and its all peachy now the other pc i put the HD 5450 to replace the gt 220 and i installed the ati driver but the gaming evolved app wouldn't install and wasn't moving so i turned off the pc and tried it the next morning and im greeted with a blue screen so i started it in safe mode it was fine then i restarted it and it booted straight into normal win 7 and piriform speccy is showing that it has the 5450 installed but when this pc starts it blue screen's restarts and then runs fine
