Alan is having more trouble streaming video. Is his computer too old? Leo says probably not. The processor is fine. Should he clean up his computer then? Leo says that's always a good idea. Do a local backup, and then format the hard drive and reinstall Windows from a known good source. Then update it. The computer will be fresh as the day he bought it.
It could also be that his internet speed is lagging. Alan should go to SpeedTest.net and he can find out how fast his internet access is.
