I'm using windows 7 32-bit. I don't know why windows explorer restarts everytime I try to navigate to the folder where I download videos. What might be the cause of this? I tried scanning the whole partition with avast free(updated) but it cannot find any threats. I tried navigating other folders with the same depth but it doesn't restart.
A corrupt file can have this affect sometimes. Or a damaged sector on the harddisk.
Is explorer trying to create a preview of the file, or thumbnail? if so, turn this off.
Run the windows chkdsk on that drive.
