Everything works well, except that when the computer is in "Sleep" mode, it shuts down on its own. When I open the computer again, it tells me it shut down improperly. I updated the BIOS but the problem still persists. Also ran the Windows Update Forum Posting Instructions. The SFCFIX found one corruption and fixed it. Here is a link to the CBS files CBS.zip I'd appreciate your help with this perplexing issue.
