Hey guys, I'm new here 
 
I'll start of with my setup:
PSU: Evga 550 G2;
CPU: Ryzen 5 1600x;
GPU: Pallit Jetstream GTX 1060 6gb;
MOBO: Asus Prime x370 pro;
RAM: G.Skill Ripjaws V DDR4 3200Mhz;
OS: Windows 10;
Warranty for everything is still available.
 
So my problem lies in loosing power in my pc. Whenever heavy loaded/tested/gaming my monitor looses signal, and pc is not responding to anything - literally, no clicking, switching, even power button - just manually pluging it off helps. I'm aware that it sometimes is connected to OC but no matter if I did some or have everything set to default I'm experiencing these freezes. Funny thing here is I can't right now test my components because any software that is somehow connected to hardware(CPU-Z, HWInfo, etc.) crashes my PC after ~1 minute. Probably they don't work as they should together. However few days earlier I could check everything and my Temps in stress was around 58-59C on CPU and 68C on GPU. Voltages on 3,3V; 5V; 12V; were +/- 5% from stadard values as I remember from 5-10 mins tests just before crash.
I was thinking about maybe some malware or corrupted W10 but even just after reinstalling OS none have changed. Did updates on my BIOS and other components. Extremaly rarely my PC regularly crashes(if it can be regular, oh well...) and restarts with Kernel-Power 41(63) error in event log. I'm asuming it might be my PSU - any ideas what I could do with it?
 
Just a little note, my PC act's more or less stable when CPU voltage is set as default - 1,55V which i find way too much to have for 24/7 use. I've tuned it down to 1,35V.
 
I'm a little bit tired of this situation, even went to local pc repair and these guys aimed at failing SSD drive which I send on RMA but... problem persists. I've tested my PC thoroughly, checking for failing:
- RAM(memtest) - no errors,
- GPU(furmark) - no errors,
I've managed to create Crash combo lol, no matter what settings I choose for him, he can't stand 1h OCCT test then 1h Prime95 FFT test and then 3D Mark medium + high performance. I've been asking this question on several forums and none could help me. 
 
If You couldn't help me I'm about to take my PC for a 150KM ride to some big city for 'professionals' inspection with high end pc service. If they will be helpless the only thing left for me to do is send all my pc parts for rma. Please save me! I'm not a newbie in PC's, builded few, repaired few in my life, finished CS studies - but right now I feel desperate with this one - he turned from dream machine into nightmare.

    There have been issues when running HWinfo 64 and ASUS DIP5, for example. On my PC I'd lose USB connectivity (mouse, keyboard, etc...) and signal from the VGA. The power button was also rendered useless. Had to turn off the PSU in order for the PC to respond. I was advised not to use HWinfo with DIP5 on the ROG forum. After a day or two, these symptoms simply disappeared.
     
    Before taking any drastic measures, avoid using HWinfo and see if the problems go away. I know it's a great program but it may need to be sidelined until compatibility issues are resolved.

    Time to put the voltage back to stock.

    Well it isn't 100% stable there more or less 90% of time stable. However AMD guys told me that I shouldn't exceed 1.4V on 24/7. I won't risk damaging my CPU when people with same setup have stable clocks with 1.2V. Problem lies somewhere but I don't really know where :/

    The computer keeps running when the above occurs? If yes, the problem could be coming from the gpu. Can you test the gpu in another good known working system?

    I suspect that the issue might be with the motherboard but it is a little difficult to conclude. It sounds like the default BIOS settings are a little off as well. 1.5 volts at stock settings are high for any CPU, regardless of Intel or AMD. Are all of the BIOS settings completely at default or do you have any XMP or DOCP profiles enabled by default?
