This is my first post.
My computer (VAIO, 2.4GB P4) runs fine until I open the D: drive which I use for processing video.
It has always worked fine, then suddenly one morning the computer goes to 100% upon opening, making work on the files in D: impossible.
Task Manager shows explorer.exe running at 99% continuously.
This AM it seemed to work for a moment, but then went back to 100% making work on video files impossible, and slowing the entire computer down no matter what the app.
When I close D:, it remains at 100% for a few minutes, then returns to normal at about 7% +/- .
So long as D: is not accessed, all is ok.
Help ?
