I recently built a new computer last week. New CPU, new Mobo, new Ram, new CPU fan, new SSD, and fresh install of windows 10. Kept my old GPU and old PSU. 

Part List:
PSU: RaidMax 850w https://www.newegg.com/Product/Product.aspx?Item=N82E16817152043
GPU: Nvidia GeForce 960 GTX
CPU: Intel - Core i7-7700K 4.2GHz Quad-Core Processor 
CPU Cooler: Cooler Master - Hyper 212 EVO 82.9 CFM Sleeve Bearing CPU Cooler
Motherboard: MSI - Z270-A PRO ATX LGA1151 Motherboard
Memory: Corsair - Vengeance LPX 16GB (2 x 8GB) DDR4-2400 Memory

Everything was up and running perfectly, incredibly fast and smooth; Drivers installed, etc. The problem I ran into within 2 hours was a video lock-up/screen freeze(cursor frozen) requiring a shut down while playing a game. After this, the computer has difficulty booting: As in No POST, No power or signal being sent to keyboard/mouse/monitor. To get it to boot again I usually have to unplug the PSU for a few minutes. But, this problem just repeats itself.


I have been troubleshooting for 4 days. It seems the hardware is all good after testing individually. Questionable faulty motherboard/CPU as always but the products are brand new. I'm just a beginner and have built PCs in the past but I have never run into an issue like this.


How to Reproduce the Issue:
The freeze can be reproduced by playing games for 30+ minutes or running stress programs like Prime95(I read Prime95 isn't the best test, its more like CPU torture). The freeze most often happens immediately when I EXIT games and also most often when I STOP the Prime95 test. The freeze has happened when I was idle in a game as well. 

Other info:
The computer never freezes idle on the desktop

The computer did not freeze under a GPU stress test

I have not adjusted any overclocking settings; should all be on default
Temperatures always look fine



I have read about conflicts with motherboards/cpus in regards to BIOS/Defaults/Voltage/Overclocking. Does this apply?

Does it seem like a power/voltage problem?

Could it be poor power from my house/outlet? 
Does it seem like a BIOS problem? 

Video BIOS problem?

What should I try next?

I am unfamiliar with PSU issues, BIOS, voltage, overclocking, etc.

Check to make sure that your fans are running - particularly CPU and video card fans.


Please run this report collecting tool so that we can provide a complete analysis: (from the pinned topic at the top of the forum)   http://www.bleepingcomputer.com/forums/t/576314/blue-screen-of-death-bsod-posting-instructions-windows-10-81-8-7-vista/
NOTE:  On problem systems it can take up to 20 minutes for the log files to complete.  Please be patient and let it run.

If you still have problems with it running, there's an alternate tool here (direct download link):  https://github.com/blueelvis/BSOD-Inspector/releases/download/1.0.5/BSODInspector-1.0.5.exe

Please zip up the (.ZIP) files - do not use .RAR, .7z or other compression utilities. 
.ZIP is the type file that can be uploaded to the forums.



While waiting for a reply, please start with these free hardware diagnostics:  http://www.carrona.org/hwdiag.html

Please start with the video tests (Furmark and the "Other video" tests), but complete ALL of the tests and let us know the results.


Good luck!
