Windows 10: PC restarts when watching streams or videos from YouTube or Steam.

Hi, im currenty having an issue with a PC i just recently built. When ever i start a stream or video, maybe 2-3 minutes in, my PC would start randomly. There isnt a blue screen that appears when it restarts, just a black screen. It can also happen when i use spotify for about 5 minutes or less. When i do play games though, it has never restarted once.

I have no heating issue since ive checked the temperatures. Ive done a stressed test with my CPU and it was successful. My RAM seems to be fine, since I also put in my friends RAM from his PCthat works fine. It still restarted with his RAM inside my PC. Ive downloaded all the drivers i needed and have also check if they are up to date which they are.
If anyone may have an idea on whats going on, Id take all the help i need.

:)

 

When Watching Streaming Videos Online

Actually its not really streaming. My internet is fast so the line that moves before the actual video I am watching goes faster. So essentially I think I am not streaming for Youtube and all the other providers that allow content to be downloaded and then watched. As for Netflix and Hulu, I believe that is streaming right? Because it doesn't allow cache to be downloaded rather it is solely streaming.

then it may be the router or the internet card. one tab means nothing. its whats in the tab that can be an issue. watching youtube while streaming? mistake.

playing a flash game while straming? mistake.
Watching porn while streaming? mitake
Skype while streaming? mistake
windows updates while streaming? mistake
other pcs loading the network while streaming? mistake

cpu power ram etc could also be a problem. if you have a mixture of lowend devices such as but not limited to.

cheap router provided by isp
old processor
old harddrive (cache)
not enough ram

blah blah. then it may coast $$ to fix it. as almost everything at that point may need to be upgraded. then you get into conflicting codecs virus scanners network/bandwidth monitors programs that access the net, the list goes on.

LOL

Well, I know for a fact that when watching the HD contents in Hulu, Netflix, Youtube, etc.. on the GX270 and the laptop the CPU goes to 100% and stays at peak until I exit and the CPU goes back down. When watching Super HD Rips (10GB) movies on the laptop and GX270 using VLC player the stutter also persists and the CPU goes to 100%. I can only watch 1GB Shit Quality Rips and the video will play fine.
