PC Crashing Issues (What should I upgrade?)

[grimlock65212]

I play a variety of games, mostly CS:GO and some other steam games, I can reach around 200 fps in CS:GO, but if I go to that point, my PC usually crashes and black screens. I have already upgraded my power supply, but that only solved 1 or 2 issues, my computer still continuously black screens when I play CS:GO, even when I set max fps to 60. I am wondering what I should upgrade to try to stop this problem, Thanks!

PC INFO (I have an old pc by the way):
Processor: Intel(R) Core(TM) i7-2600 CPU @ 3.4GHz 3.40GHz
RAM: 16.0 GB Dual-Channel DDR3 @ 668MHz
Graphics Card: NVIDIA GeForce GTX 580
OS: Windows 7 Professional 64-bit SP1
Motherboard: ASUSTEK Computer INC. SABERTOOTH P67
Storage: 698GB Western Digital WDC WD75


BY THE WAY: When my computer crashes, it pops up a message saying "DVI Power Saving Mode" or something similar to that.

If you can play at 200 FPS, I doubt it's your hardware. A quick YouTube search shows an easy fix for this that has worked for many.

The crashing is not solely CS:GO, I play other games such as realm royale and I crash often as well. I crash even more when I do not limit the fps in my games to 60. I will try this fix for CS:GO though, will let you know if it works.
