PC randomly restarts

[2ndmaiki]

Hi guys, I have a problem with PC it just randomly restarts. After that it shuts down and it wont boot. This happened to me multiple times during few months. My MB got 4 LEDs for CPU, DRAM, VGA and BOOT. It should turn on if something fails. Usually the CPU LED turned on and I just turned off and on power supply and it worked but today turned on LED for DRAM and VGA too. I tried again to turn off and on power supply but it still didn't work. I have another system with i7 6700k so I tried to plug RAM and GPU from the Ryzen PC to this and it worked. After that I tried to plug everything back as it was and Ryzen PC booted normally. I tried to check temps but they were fine (GPU max 72 C). I have no idea what may cause this since it just temporarily don't work. It's like completely random, sometimes it works sometimes it does not. I've never tried to OC anything. If u have any idea what might be the problem it would be great. Thanks for answers .

what I would do is try to crash my system on purpose, and in a way I can reproduce. 

but first thinks first

 

 

How to force crash your system BEFORE Disabling XMP 

 

get furmark(GPU) and Prime95 (CPU and RAM) and let it run both, if it crashes try only one of them and then the other. but be warned that is 100% utilization and at least furmark warns that you might damage your gpu. It did never for me but you should be warned. 

 

in general 

 

your RAM. you said you never OC anything BUT your ram is at 2993 Mhz. you must have XMP enabled to do so. that is one OC. 

try disabling and check if our system crashes.

But what would I get from that?  Anyway I don't want to risk losing my gpu since I can't get a new one for normal price. About the ram it is rated for 2993 Mhz I meant I never went above sorry about that.

Also I should mention the pc worked fine before I swapped case and GPU. The GPU was in that i7 system before and it worked fine without crashes. There were also RAM OC to 3200 (Maximum for board).

you could also test with the old GPU if your system still crashes. there are tons of possibilities why your system is instable

well, i suggest you to check the event viewer, windows will log what caused the system to crash, check if there is any problem, if you don't understand the meaning of each event, you can send me the suspicious event or google it its meaning
