Install a genuine version of Windows 7, then update it to at least SP1. Counterfeit installations are difficult to diagnose since they contain heavily modified code that could well be the cause of the BSOD themselves.

there is no way for me to get a genuine version of windows 7, the problem occured when i updated my graphics drivers, can you please help me without the update to SP1

 

[GWAlistair]

i uninstalled the nvidia drivers and am re-installing them from the website

 

[GWAlistair]

problem persists even though i updated drivers (they were already updated to the version i downloaded i just did a clean install) i am now reverting my drivers to an older version to see if that helps with my problem will run until i get another bsod

 

[GWAlistair]

just got another bsod after reverting to older drivers... i'm stuck i don't know what to do :/
