Computer Black screens while watching youtube

[Atkinson92]

Recently I have this problem where my Display Driver will stop working. It's always when I'm browsing online, more specifically youtube. Sometimes it's when I load a video, other times it's when I try to adjust the quality. It never happens when I'm on a game. Sometimes it recovers itself and the monitors will come back on, but I usually have to do a restart. It happens about twice a day.

I re-installed my driver but it's still happening. I used a website to calculate how much power your pc needs and it says I need around 450w and I have 500w. I will put a link to my power supply and graphics card below.

Also, I recently upgraded my motherboard, CPU and RAM. I remember this used to happen with my old PC about a year ago. I have updated every part since then. It has nothing to do with my temperatures either. My graphics card is at 40 celcius right now and it just happened again before I posted this.

Anyway, here is a link to the parts I'm using.

GPU- http://www.amazon.ca/gp/product/B0088PK040?psc=1&redirect=true&ref_=oh_aui_detailpage_o06_s01

PSU- http://www.amazon.ca/gp/product/B00H33SFJU?psc=1&redirect=true&ref_=oh_aui_detailpage_o06_s02

Also, here is a link to my full specs incase the problem is with something else.

First off your RAM seems to be running slow, that is unrelated, but it should be running around 1333MHz or higher unless it is made to run that slow. for the GPU that may be the powersupply. It says it can deliver up to 480 on the +12volt rail so if your PSU is being used a lot which would make sense with the 8 core beast you have. it may be over taxed thus explaining the black screens which can be caused when the card needs more power than it has. do you have any overclocks or under clocks? sometimes they are unstable and I have found them to crash on youtube before.

Yes, actually I didn't think of that. I have my processor at 4100mhz and the stock speed is 4000. I will try putting it back.

Also about the RAM. I looked it up and I guess that's just how Speccy displays dual-channeled RAM. Other people were saying it doesn't show the full MHz aswell but that's just how it shows up.

Edit: Is it normal that my CPU changes speeds on its own?

yes, that is called turbo, often a processor will not run at full speed if it does not need to as that wastes energy and produces heat for no reason. then when full power is needed it speeds back up. let m know if the clock speed change changes anything.
