Hi y'all. Thanks in advance. I have a laptop with Vista Home Premium a couple years old but all up to date and everything. It was working fine, but I was messing around in the startup menu tonight and accidently cleared the wrong box. To make a long story short, after the machine restarted, nothing worked. I can't access system restore to fix it because it tells me that system restore isn't working, and that the volume shadow copy service isn't working. The error code on that is 0x81000202. Also the event log isn't working, apparently Windows Explorer isn't working, so much isn't working, and it won't connect to the wireless router so I've lost the Internet connection. I don't even know enough about the problem to say what exactly isn't working, but the machine is useless now. I've run every internal diagnostic I can find and the memory is fine, but something critical obviously stopped running when I cleared that box. I can't access the startup menu to reconfigure it either. Does anybody have any clues as to what I've done and how to fix it short of doing a clean install of the operating system? Thanks again.
