also this is the new amd xfx1 hd 5450 1gb ddr3 but for some reason it still comes up as a readon
System :
MSI P31 NEO intel 2duo core 2.66
Psu 500 watt
ram 4gb
had 250
graphics card readon hd5450
Ok, So here is the issue, Every time I start a game, the video card stops responding or the computer freezes, I read that someone thought it was a psu problem so I upgraded mine to the 500. still does it. I changed out with 4 diffferent graphics cards still does. Bought new ram still does it. reset the bios, still does it. reinstalled windows still does it. Edited the reg with the trd thing that delays the computer instead of freezing. still does it. updated driver same thing.
I really do not know what to do, other then replaceing the motherboard, I have done 6 differnt scan on the hd all come back good.
Any Ideas any help would be wanted
