when i reinstalled windows xo everything seemed to be running fine then i let one of my friends on i dont know what happened everything seemed to be running slow so i checked my processes list in task manager and some processes were taking up 50 k to 150 k im not sure if thats virutal memory or not but it is slow down my computer such as pauses in video games programs freezing for long amounts of time and such any ideas on what may be causing this ? if so please tell me
