lol, although my PSU was fucked.. and i replaced it with a unused 300W psu (till my order arrives)
i found the problem was, that in BF1942, the video options give u an option of ur refresh rate.. o dear.. me with my lovely large 21" TFT screen, that i'm only running at 70hz.. and i was running it at like 85 or something.. well over.. anyway it would randomly crash when large frame rates were needed.
either way, my pc is now fine and will be ALOT better once my new parts arrive.. :D
infact im going to change my sig now :) yay 4 moi!
