Thanks

On AVG tuneup, originally I had a message that there were 14 problems to repair. When I open the equipment performance and started, it will quit and display a message (fail to load windows library msxml3.dll). For an unrelated cause, when I started windows again, the screen began to flash and could not do anything or open any program. Windows sugested to REFRESH it, and I did. However,  in the process unloaded all programs and kept only windows realated apps and programs. In other words it reloaded Win 8.1. I have reloaded AVG, and the message before changed to 11 problems, but the failure remains. Is it windows realted or AVG
