As for the video card drivers - ALWAYS get them from the manufacturer, NEVER from Windows update.
That is very, very ill informed advice. The drivers available from Windows Update may not be the very latest, but they have been validated and validation is important when you're trying to troubleshoot an installation because it removes a critical variable from the process.
So true, My brother had problems with his card's.
x2 XFX Nvidia 9600GT 1GB {SLI enabled}
He used XFX drivers before, the last 2 updates they produced now caused screen flickers when Flashed, Stunned or Smoked in Call of Duty : World At War. It doesn't do it in Call of Duty 4 or any other game for that matter, All games are set at highest settings, he even tried using optimal settings, still problem persists.
He then removed all his video drivers and tried straight nvidia drivers, still problem occured in COD5.
He then uninstalled his video drivers and downloaded + installed the ones from Windows Update, Problem is solved.
So, my question is "whats wrong with drivers from Microsoft?"
Drivers from Windows Update has saved the hassle of waiting for my manufacturer to make a new driver for Win 7. The drivers for Vista just refused to install in Win 7.
Did a Windows Update scan and bingo, a driver for my device, otherwise Id be waiting for a few months :huh:
So far Windows Update hasn't let me down
