I’m sure it’s missing the driver. I D/L’d all system drivers for XP and think they’re reinstalled right. But still get no sound. I’ve done this before and it all worked?? Help.

I want to play the game Timeshift but all my video card and other computer system drivers are horribly out of out of date . Is there any site that i can go to so that i can scan my computer and find out what driver downloads i can put on my computer to bring it up to date and make it faster and make the games stop freezing . I need to have a site that does not have an unknown publisher and is a reputable site. Are there any sites that do the scan and update drivers so that i can get my computer in tip-top shape?
