Hey guys - I have a dell inspiron 530 desktop, core2 duo, running xp pro. after a while (maybe an hour or two, usually happens when im on firefox/internet, but still trying to figure it out) windows (including all other apps) will freeze up entirely, except that the mouse will still move. then after five minutes, no more mouse movement. I dont think its the memory, i've swapped in different memory modules. i can't quite figure it out. next thing im going to try is to swap out the wireless wifi adapter, issues could be caused by that driver. ideas?
