My OS is Vista home premium and if I shut my PC off (not restart) for longer than a few minutes I get a blue screen for msahci.sys when I start back up. Something about corrupted page file in non-paged area or some such (should have it memorized I see it almost daily).
BSOD most often happens just before desktop loads and causes system to restart. Normally goes through this several times before finally loading windows and going to desktop.
Any of the other Vista users here having this trouble? Maybe even found a fix for it.
