Why My Windows PC has become slow and keeps crashing or showing display and sound problems. I think the drivers are outdated, but updating them one by one is confusing. Is there an easy and safe way to update all drivers at once?Yes, outdated drivers are a very common cause of lag, crashes, no sound, and screen glitches, especially on older PCs. You have a few options: Use Windows Update. Go to Settings > Windows Update > Advanced options > Optional updates
