Okay so i'll get straight to the point as im a new member to this board but browsed it previously for other problems. I Used to have WoW and i suddenly started getting the nv4_disp.dll error, it annoyed me that much i quit WoW, here we are today i wanted to get back into it, so i format my whole computer and installed Windows 7 (previously had XP Home) and a similiar problem happens. WoW just locks up and my whole computer freezes. i cant move the mouse or tab out or anything, the music is looped from the speakers and i have to shut down manually by holding the power button. These are my comp specs. Windows 7 home premium 32 bit intel pentium 4 CPU 2.66GHz, ~2.7GHz 1536MB RAM NVIDIA Geforce 6200 (128mb) Im not too sure on what else to give you but if you ask i will provide. In my performance information and tools window in control panel it says: Processor: 3.5 RAM: 4.4 Graphics: 2.7 Gaming graphics: 3.2 Primary hard disk: 5.1 Normal use is 100% fine, but it just freezes when i start WoW up. do i need a better processor? more RAM? a better graphics card? im useless when it comes to hardware Any help is appreciated thanks!
