this happens to me frequently on my laptop where I shut the screen and it goes into standby then later I open it and my computer has restarted itself! then I get the windows error reporting message that "windows has recovered from an unexpected shutdown" It is getting annoying. my computer is a year old.
I have included the files necessary. Parts 1 and 2
part 1 contains 1/2 of the autorun analysis and the vista health file
part 2 contains the other 1/2 and the belarc advisor file

any help would be appreciated! thankyou

Info needed:

windows vista home premium X86 service pack 2
pentium T4200 @ 2.0 GHZ
