If the drivers on your computer are corrupted/mismatched/missing/outdated, it might cause problems like stuttering sound, snowy screens, blue screens of death etc. So we might have to update our drivers to the latest to keep our computer in good health, which in the long run might save us from all the hassles, headaches and trips down a computer repair shop.
