Allot of my daily computer useage is importing and exporting graphic files from/to different applications. Until yesterday this worked as expected. For whatever reason now when I do this 'ekrn.exe' decides to goto 100% CPU for upto 10 seconds which locks the entire system. It's incredibly frustrating and never occured before. I updated to 3.0.669.0 in hope of it stopping but it doesn't. Whats going on?
