I seem to have encountered lots of problems with my new Netbook PC, featuring Windows 7 Home Professional OS. For example, I can't shut the system down unless I turn the power switch on. Sometimes, I get a system malfunction screen and I need to shut it down. I went to a Windows Repair website, but most of the free repair sites aren't free at all. I need some sites that both free and easy to follow instructions(even if I have to print them out).
