The WEI is worthless - ignore it. It sounds like you are having driver issues. Windows update can be a real problem for HTPCs because it will break things that work by upgrading drivers in the background. Chasing these issues is frustrating and can take forever. Start by (fully) removing each driver and updating to the latest versions. You can also run javara then install the latest java.
