Lag spikes..?

[Miagi]

Since it's all games, that narrows it down to a connection issue or virus.

If you have nothing running, do you see a lot of network traffic?


Do you have any routers in your setup?



Could also be a faulty router in one of the hops to the servers. Can call your isp and see if anyone else is complaining.



You could try going to start->run type cmd and ping a server a few times.
