Is my GPU or CPU failing?

[michaelr8709]

Sometimes, if I open multiple tabs of Twitch or youtube for instance, my entire internet browser crashes. Also, while playing games, if I am also on discord, my discord will crash. I was just playing Overwatch and my entire computer crashed. After turning my computer off and back on, the PC only had a black screen I had to unplug everything and it finally turned back on. Is there a way I can see if it is my CPU or GPU. I don't have any spare parts so I cannot replace any parts to test it.
Thanks.

If you have integrated graphics...try and pull the GPU and run just on the integrated graphics. This will tell you if it's the gpu or not.

The graphics are dedicated.

Then it would be great if you could just get a hold of a cheap graphics card for a test.
Obviously this would be easiest.

Other than that, I would open the case and go through everything....make sure all the cables and cards are seated...make sure the cooler is on tight....etc....

Have you looked at temps?
