82945G Graphics Realtek RTL8168C Gigabit ethernet adapter ALC888 sound chip I have tried newer drivers, but it seems to make the problem worse or no better, right now it may not do it for weeks, then when it does act up it seems like it does it for several days, rebooting several times today, then its back to normal. I have tried to notice if I am doing anything different on those istorm days, but cannot correlate anything, I don't do much but surf and email, analyze a few minidumps occasionally. I shut down the PC every night. Here are the full hardware specs http://eu.msi.com/index.php?func=prodtmpspec&maincat_no=134&cat2_no=&cat3_no=&prod_no=1674 All I can do I guess is try the latest drivers again, maybe there are newer versions. I am beginning to think it is a Windows 7 bug running on this particular hardware, just won't play nice together. Thanks for looking. .
