A couple of weeks ago, my computer unexpectedly turned off with fans working. I turned it off by long pressing the power button, wanting to restart. But when I tried to start it again, I faced the same situation: fans were working, but there were no image, nor disc activity. I turned it off again and waited for some time. After like ~5 minutes of waiting, it started fine.
In order to investigate it, I came to the Windows Event Viewer. I noticed that right before this weird shutdown there were a lot of WHEA-Logger Warnings with code 47:
A corrected hardware error has occurred.
Component: Memory
Error Source: Corrected Machine Check
There were about 50 warnings for I second. I decided, that this was the reason. Here some facts I noticed about this warnings:
- It usually occurs under heavy load, such as running a game.
- It also can randomly occur in the first 20–30 minutes from the PC start. And, what seemed interesting to me, warnings occur at the same seconds of a minute. E.g., if there were a bunch of warnings in 19:30:46, so there could be another bunch of them in 19:31:46, then in 19:32:46, and after 2-3 iterations it stops.
- OCCT were also complaining about those warnings during the RAM test.
I tried all the guides I found, like switching the places of RAM modules, disabling memory throttling in BIOS and removing some modules. But none of these helped.
The temperature of my PC is quite fine. It is also fine with power supply, I believe (I checked the voltage in AIDA during stress tests).
My specs:
- Huanan X79
- Xeon E5 2680V2
- 32 GB RAM DDR3
- GTX 1060
What else can I check or what can I try to fix it? (preferably without the need to replace hardware). I would really appreciate any help!
