1) When I turn off my PC at night, which I do every night, should i turn the power button on the back off my PSU off as well? Or should this be left on?
2) My hard drive has recently begun to make very light, and what seems like, scratching noises. It only seems to happen when data is being written or retrieved. What could this possibly be? I have no idea how a hard drive really works. Are there moving parts in there besides the disk spinning that could be scrapping? Or could it simply be a disk reader making those noises as it moves?
