So when I was using my gtx 560 ti, it would crash and shutdown my whole computer if i played any game on high settings. Even on CS:GO i had to change the quality and other settings to low/medium. I thought it was the graphics card so i upgraded from a GTX 560 ti to GTX 1070. But even with this new card it will still crash and shutdown my desktop if i played any game on high. Now i know this isn't the GPU because its brand new. So is the Processor which is an i7 4790k.
If i use the computer to watch YouTube and such, it won't shut down randomly. It'll work perfectly fine. It only shuts down when i play a game on high settings. I was planning on buying a new PSU but I don't know which to buy and I am low on cash so i need to buy a good power supply for as little as possible.
My Specs:
CPU: Intel Core i7 4790K 4.00GHz
Motherboard: ASUS Z97-AR
Memory: DDR3 4x4GBs
GPU: Geforce GTX 1070
PSU: Kingwin ABT-750mm 750watts
This is my first post ever and not to mention i don't know how to correctly give my specs to others. Sorry.
