yea i bealive it was to do with ram
i found a little solution where you change the settings so the system set's the ram performance..it was using 2046 when i cheked, but when i set it to system settings it restarted and started using 3360 units of ram.
how i know its ok now..because i couldnt turn on after effects - it would give me a BSOD at the loading screen half way now AE loads perfectly and it loads in like 10 sec LOL
i didnt do anything to cause this..i dont think its my actions, cuase the latest on i left far cry 2 in main menu and went to watch 'Last man standing' and came back it was stuck at BSOD
anyway it seems to be ok. thanks again man priciate all your help. allthough im not out yet ill comeback when im ready to OC hahaha :d
cheers
