This is my 3rd computer I have put win7 on and have had no trouble on the others and a ton of trouble this time around. I did a clean install...twice and am still having issues. As you can see in the attached picture there are numerous icons on the desktop that have no picture...they are plain white. Also, the taskbar icons are transparent...you can still click on the area they are supposed to be and get them to open. I am also unable to keep explorer going...it continues to freeze up and stop responding. Any help is appreciatexd!
