i have just installed my new Asus Nvidia Geforce 6600. I am having problems, when i first installed i got a lot of freezing in gaming(WoW) forcing me to restart. Also in CS i was experiencing white lines in alot of places. I finally installed a update video display driver and couple problems went away while new ones arose, now i am getting like 1 white line on loading screens in my game and lines that blend in on color of object. I was told to update my BIOS which i plan to do. My question is when i install like display drivers should i be deleting my old drivers. I was told that i should be deleting old drivers and putitng new, so should i just unistall the Asus video card driver disc and just install straight from the site. Also should i be downloading just the newest of each driver? Any advice would be appreciated
