It crashed. First my Google toolbar disappeared before my very eyes then some desktop icons, then the entire desktop and the screen went black.

Something weird happened once here that my pages got all messed up and I took a screen shot because I was the only one it happened to.

Anyway, I have no idea what my brother-in-law did to rescue me, but it's up and running for now and we're going to buy him dinner as a thank you. Gonna do that whole virus scan, adware scan, defrag etc. thing.
