i need some urgent advice. either my computer is possed or has some sort of virus. here is what it does. cd tray opens and closes anytime. im not even doing anything with it. the screens when i open a new page only open half size. i have to hit the full size button everytime to see the whole page size. pages suddenly close or my downloads suddenly end during downloading. can anyone tell me what program is good here that i can use to fix this? so far all i know how or what to do is hit the system restore? any advice is urgently needed thanks.
