I click on Start, then Pictures. It takes about a couple of seconds for pictures to update all the files that I transfered from my video capture software. For some reason it won't update and it freezes my system to the point where I have to use CTRL+ATL+DEL to unfreeze it. Sometimes I have to shut the compuetr down via the power switch when picture freezes. All other programs like Documents, etc. will open OK. I've never had any problems like this before. What could be causing this?
