I just installed my 770 gtx asus graphics card and when ever I play a game within 30 minutes my computer crashes causing a annoying loop noise and my screen goes black. This has also happened before I installed my new graphics card but its just more frequent now. I have looked everywhere to find a solution and I couldn't find one. I don't know if its my Motherboard, Graphics card or my CPU.

Edit: It also crashes when I'm just casually using it, the screen just goes black. I think it might be my CPU getting overheated because I have liquid cooling that you can't change the liquid.

my specs are:

CPU: AMD Phenom II X4 965
Mobo: Gigabyte GA-790XTA-UD4
RAM: 2x 4GB DDR3 G.Skill
GPU: Asus Nvidia GeForce GTX 770
PSU: 700 watt
Case: Cooler Master Mid tower

Could be something overheating, or possibly, the PSU can't handle the amount of power your card needs under load. what PSU do you have?

oh sorry I forgot to add that.
I have 700 watt PSU and I heard that the GPU requires a 600 watt PSU, so I should be fine with that.

yeah a 700w is way more than enough juice. I'd check your temps to make sure everything is running cool. If everything is running good though, the only other issue I could possibly fathom is a short in your motherboard.

I'm pretty sure it was my CPU overheating because I could smell something burning and my liquid cooling pipes were extremely hot. So I'm just gonna replace my stock liquid cooling with a cooler master fan and see if that works.

Run CoreTemp and check your temperatures. You can find out for sure, Idle, you should be no higher than 30-35C

It's at 35C idle and i just installed a cooler master 212 plus. So I guess its not the CPU.

I would say check your PSU then. It might be defective. I can't really decipher much more without actually being there. :(

My computer is 5 years old and I'm just starting to replace some parts so I don't know when things eventually die or what not, but is it possible that the CPU could be damaged or my motherboard being defective?how would you go about checking the PSU? Thank you for your help by the way. I really appreciate it.
