And after the crash I cant boot it in normal mode, just safe mode, it also crashes with some other flash features, have not tried playing a game to see if it crashes too, will update with this later (after it crashes I have to wait a while to boot it on normal mode again, if i dont it justs goes to a black screen but everything keeps working like the fans etc)

Check to see if any updates hit and installed while you where booting. It sounds like video driver or flash incompatibility issue. If there were no video driver updates try rolling back your adobe to an earlier build.
I have the lastest driver of nvidia and have the lastest adobe version, by the way, just checked trying to run a videogame (the witcher 2, which runs good on this pc) and it crashed as soon as I got to the menu screen.
