Thank you for your suggestions, i did change my screen settings, and wow yeah it works . Brilliant. Sadly though the game will only run for a short period i.e 5-10 mins, then i get a system reboot. I appreciate there must be countless reasons for this, but I'm certainly open to suggestions before i take my pc to my local store, to see if a upgrade would help, not sure if i'm throwing money away though. Not sure if the cpu heat is to much ? dont know how to check. Dont know a lot really, sorry, and thanks again....
