Crash, Don't know why?

[Sergei Drew]

Okay, The problem is my PC, I don't know what's wrong about it, i just know it's wrong, and it's making me really mad.
The problem started after i upgraded the system [3 months ago],
The system specs are:
- CPU: AMD FX-9590 Octo-Core 4.0Ghz
- CPU COOLER: Corsair H60
- GPU: Nvidia GTX 970 SC
- MOTHERBOARD: ASUS M5 A97 R2.0
- RAM: 8GB DDR4
- HDD: 1TB
- Power: 1500w
- Windows: 10
The problem i have is my PC will crash, But not like a bluescreen or file dump, But the whole screen freezes, Mouse and keyboard input no longer works, and all sound cuts out, But the PC remains running - Fans, lights and monitors stay on, So i have no idea what's going on. What i've found is that i can leave my PC on all day, Before i go to school i can turn it on, And i'll come back and it'll be fine, But as soon as i start playing games or doing anything that requires a little more that idle power, [Games, Photoshop, rendering, Opening lots of tabs] it crashes, And now it's really annoying me as i can't do anything, i don't know what's wrong, but i do notice frame drops in games like counter strike, a game that i should get 300+ FPS on, but i go down to numbers below 10 at times, i have no idea what's going on, and i'm worried that one day it wont turn on, and i'm not sure i have the money to buy the parts i want at the moment, so if any one could tell me what's wrong, Or what i can do to find out, that would be great, It's getting REALLY annoying.

first try... is turning off turbo boost in your bios, and try playing a game. alot of cpu do not wok well with turbo boost (or turboV for your bios) on, because the Vdrop on the cpu would make it unstable. If you want a overclock where vdrop doesnt happen, go to your bios and turn off any power saving features. just turn off TurboV and play a game and let me know what happens.
