I am using windows 7, and have had great internet connection. While I was in the middle of running a game, I bumped my USB speaker system, which caused a blue screen error. After I restarted my computer some of my USB ports were not working and my internet connection is very strange, it can connect but will drop after about 1min, then take another 5mins or so to connect, all other PCs on the network are fine. I considered a system restore, but I have no restore points.
Any ideas how to fix it? does it sound like a software or hardware issue?
