I have a very annoying issue that I'm trying to fix but I keep hitting dead ends.. When playing pso2 it runs fine no lag but sometimes it just hard locks up my pc and i got to hard reset the system. This also happens when i afk in the game over night. (Also it does not give any error what so ever)

I've tried everything to remedy this issue from updating drivers, updating windows, reinstalling windows, reinstalling pso2, swapping out RAM modules (mostly everything technical) I run the game from steam ( recently pso2tweaker )

Anyone have any CLUE why this is happening? I'm litterly smashing my face on my keyboard -.-
