I have a L7VMM3 mobo, the problem is my system freezes randomnly, each time I install a Video Card on the AGP slot, I have tried 3 working gforce cards, I know they're working cause I tried it on my other systems, I have heard of PS problems, I have a 350w PS, should I upgrade it? by the way, I also tried the onboard video that comes with the mobo, it works fine for some games, but for some memory and video intensive games such as those that uses openGL, it freezes, what do u think is the problem? could anyone help me out
