1. Get out the canned air and give the vents a cleaning (how is now on the web, youtubes and more.)
2. Google this. "How to disable Flash Hardware acceleration." Varies with the browser so for each browser disable that.
I have a Lenovo G50 laptop with Windows 10 installed. I've had this laptop since May, and this problem only started happening in the past few months. Basically, out of nowhere, a YouTube video will just not play, despite buffering completely. My Spotify won't play any music either. During these "episodes" where my computer is freaking out, I usually can't log onto my Gmail because it won't load, and Google searches will crash and a little bar at the top will say "Shockwave flash crashed" or something like that. I've tried everything, but the only solution that works is if I uninstall the sound driver in device managers, and then restart my computer and let it reinstall. It'll fix the issue for maybe a week, and then it'll happen all over again. I've tried system restore (I even restored it to when it had Windows 7) and that doesn't have long-term results either. Please help! I'm so sick of this issue and I don't know what to do.
