it shuts down when i am trying to copy a file from my desktop to my flash drive. it has also done this when i copy a small downloaded program file from program files to copy it to my flash drive. it restarts in like 2 seconds but just won't allow me to copy or drag files. the files are not any important operating system files. they are just small programs i got for trying to fix another problem. the content of the file is not unsafe or anything. anyone heard of this and what may i do?
