My computer is driving me crazy. In the last couple days it's had a real problem with lagging up. I'll be trying to do something *doesn't matter what program I'm using; FireFox, Yahoo, etc.* and it will lag up. Firefox especially might give me the little "Not Responding" notice at the top if I keep trying to do stuff, but then it will pick back up and work again. It does it over and over, ever few minutes. It's getting on my last nerve. I've restarted FireFox and my computer, and I've run my usual scans with no luck so far. Why does it keep lagging up and what can I do to make it stop? It's getting on my last damn nerve.
