yeah, i put in new ram when i installed W7 so that's why i sayd so..., i tried to look at the location you sayd but the computer can't find it (probably because i have a dutch version of W7), i went to even viewer and it says this:
Het systeem is opnieuw opgestart zonder eerst correct te worden afgesloten. deze fout is mogelijk veroorzaakt doordat het systeem niet meer reageert of is vastgelopen of doordat de stroom is uitgevallen.
translation: the system has start again without being shut down correctly. this mistake might be caused because the system doesn't react ore has been stuck because the electrisitie has shut down.
p.s. thanks for the quick response
