YouTube keep getting white screen of death

I'm new to any tech support site, so please forgive me if this has been addressed already. I've spent quite a while looking for this problem before starting this thread. Several months ago soon after a Flash update I started having videos either go straight to the wsod or play for a short time then get it. It happens after I've been watching videos for a while, and I usually have more than one window open, something i always have done. I've read it's to protect my computer from crashing, that flash is needing more resources than my computer has. I close my browser, reopen then it plays, or I switch to another window and it plays, but sometimes it won't at all. A reboot brings it back again. I'm confused about the 'protecting' my computer because I'm not doing anything different, and never had my computer crash while watching videos before. It happens in IE and Firefox too. I'm happy to give you any information you need to help me. Thank you so much and happy Thanksgiving.
Flash version: 15.0.0.239

It's up to you but allot of those Unchecked items need to be checked if you ever uninstall or update the utility it belongs to otherwise you'll end up with Unknowns listed,
And between you and I Java from Oracle and Flash player really isn't needed to play youtube videos you could simply Disable Flash element in manage add-ons,

Reset ie11 would be the next easiest test,
