Hi Everyone I have been having a problem with my pc since I bought it a couple of months ago -- frequent blue screen crashes. It is a Win7 x64 system. I figured out that the crashes were usually caused when another computer was trying to access files over the network (I have a number of XP machines on a home network). Sure enough, when I set network discovery and file and printer sharing to "off" I have no blue screen crashes. I guess I have two questions. The first is that every time I restart my computer, network discovery and file and printer sharing are automatically reset to "on", so I have to go into the advanced network settings and manually change them to "off" to avoid a crash. This is a hassle. Does anyone know how to set them to "off" permanently? Now, since the above "solution" is sort of like putting an out-of-order sign on a clogged toilet, ideally I would like to get this machine actually functioning properly. That is, does anyone have any ideas how I can actually use file sharing without crashing my PC? I want to listen to my music when I'm in another room! Help!
