Hello guys, so not long time ago, almost 2 months ago I bought new graphic card and I needed new power supply so I called to service and they did it for me. They bought new power supply. swap old graphic card with new and power supply. The same day I got blue screen so I check updates, clean my computer etc. but it didn't. I'm getting blue screen when I do two things in one time for example I play wow and watch twitch and whenever I do break to watch for couple min twitch with open wow, the time I click full screen I'm getting blue screen. Whenever I start the computer everything load and I open something and black screen. I don't have any ideas what can cause this I did some research, ask my friends and the only thing I got is my friend's father said it's most likely power supply but some of my friends said is hard drive. I don't know what to, if I google it the problem I can identified with both causes. I need to find the cause before I call the service because if it their fault I don't want pay for something they messed up. My power supply is crossair CX 750W. Here is a screen shot with bluescreen and my specs. I hope this is enough information to find what's going on.
Blue Screen
This screen shot is what friend recommended to find and when I google it it showed as power supply failure. Specs
