Update: it got laggy again shortly after installing my programs and using a few of them. All I have installed besides the basic drivers/Chrome is Comodo Firewall and Malwarebytes. The only other programs I have installed are poker sites and Foobar2000.
I am getting the same kind of laggy window movement that makes it seem like I am almost out of memory but I have 4gb free RAM and 10-16% cpu usage.
At this point I'm out of ideas unless there's something faulty in my hardware, but when I freshly installed everything seemed fine but obviously I wasn't using much of anything at this point. If it does this now under a fresh Windows install and everything we have done, what is left to test out?
