So I keep my computer pretty healthy, I use CCleaner, TuneUp Utilities, Malwarebytes, my firewall is on, Microsoft Security essentials is on, and my computer is always max out in terms of basic windows operations and performance. I also have the free version of Superantispyware that i use as a stand alone scanner bc it picks up on problems and viruses (which i very very rarely get bc I know what to stay away from, and Malwarebytes will pick up on them right away and Superantispyware has gotten rid of anything bad on my system). So I ran into major hanging problems when i tried to install an Azio bluetooth keyboard, my Devices and Printers takes forever to come up and explorer.exe windows will stop responding just about every time I use my computer. Ctrl+Alt+Del takes forever as well and i usually have to wait and then right click somewhere to get the process rolling for it to come up. Even my physical reset button takes about 10 seconds to do anything, I've pressed that about 3 or 4 times out of frustration. Let me know if you guys need any additional information, but to my understanding my computer has been super healthy and has stayed lightening fast until this keyboard but it came right from the factory and i doubt it has that much to do with it. I just think windows is effing up and im not sure what im supposed to do bc even after running CCleaner, running tuneup's 1 click maintence (which does defrags but it'll say when i dont need to and it says that), and running Superantispyware, everything should b fine. Thanks alot in advance for any help, like i said let me know if you guys need additional information.
