My PC is always freezing up, not responding, crashes or just doesn't do anything. Is this problem related to my physical memory? I was told by the tech at att that my physical memory should not be all cached, and that was the reason for all the freezing and crashing. Is this correct? If so where is all my memory being cached? and why? and how do I fix it?. Also my active x's are all disabled and I have to go enable them and in a few minutes it is back to being disabled. I get no other errors except for the fading screen and IExplore is not responding and needs to close, or this program is not responding. Once one thing stops responding or crashes then everything after it does the same. My physical memory in task manager says physical memory 3070 mb , cached 2388, free 0. Then in the crashes it tells me all my drivers are corrupted and the OS and I have to reinstall help!
