My system has been suffering from random lag spikes, while running any program... from something as small as Notepad to something as big as Crysis the game. Even while scrolling pages, the graphics start to lag. And lag in a game always starts after about 5 minutes of playtime. Sometimes, it goes away if I alt+tab.
I've noticed that whenever this happens, my CPU Usage shows anywhere between 50-100%. While I initially attributed this to my Creative Audigy sound card, uninstalling the card didn't help. I don't understand what the problem is... can someone help?
