Solved Power issue with newly built PC (SPECS provided)

ISSUE:



Hello, I recently (1 week ago exactly) built a PC for personal and gaming use (specs listed below). Seemingly at random the PC will lose its display and stop providing power to the mouse and keyboard, which are connected by USB. However, the case fans, the power supply fan, and the cooling fan all keep operating in this state, as well as the light indicating the PC is on. Pushing the power button (both long and short push) does not cause anything to happen. The only way to get the PC operational again is to unplug it or turn off the power supply. After I restore power everything returns to normal with the computer starting up without any indication of error (no notification to start in safe mode or the like).

I do not believe it is a cooling issue as the fan that came with the Ryzen is stated to have thermal paste pre-applied and none of the PC’s components are hot or warm to the touch. I am not overclocking the computer.

I built the PC according to the video linked here (youtube PC build guide)

Thanks to anyone for your help, if there is any additional info required please let me know

Thanks, is it common for a psu to fail in such a selective way (i.e the cord connecting to the motherboard failing while the case power is maintained)?

Thanks, the snapshot is here

I noticed some more specific causes of the issue. As a test I left my PC on, in idle on desktop for 2 hours without issue. I also was able to voice chat and watch videos with some friends for two additional hours without issue. However, when I started playing a game, the PC had the shutdown issue within 40 minutes, which seems to suggest it is some kind of issue with the game putting strain on one of the PC components.

Thank you for the precise advice, I really appreciate it.

I was able to go into bios and disable the xmp and then set my ram to 3200

The specific game I have been playing is Warhammer 40k: Mechanicus. The settings recommended to run the game are as follows:

• RECOMMENDED:
  • Requires a 64-bit processor and operating system
  • OS: 64-bit Windows 7, 64-bit Windows 8 (8.1) or 64-bit Windows 10
  • Processor: 3GHz Quad Core
  • Memory: 8 GB RAM
  • Graphics: 4GB AMD Radeon R9 380, 4GB NVIDIA GeForce GTX 960 or better
  • Storage: 11 GB available space
  • Sound Card: DirectX compatible sound card

After installing windows I installed the chipset. I believe windows updated after this as when I was installing windows initiailly my PC was not connected to the internet, after getting it connected I installed all the chip drivers.

If it helps I have attached an updated speccy here.

Once again thank you for your help. It is a great relief to have your assistance

Here are the listed minimum system requirements:

• CPU: Intel Core i3 with minimum 3.30 GHz (if the GHz is lower than 3.30 12 GB RAM is required)
• CPU SPEED: Info
• RAM: 8 GB
• OS: 64-bit Windows 7, 64-bit Windows 8 (8.1) or 64-bit Windows 10
• VIDEO CARD: 2GB ATI Radeon HD 7970, 2GB NVIDIA GeForce GTX 770 or better
• PIXEL SHADER: 5.0
• VERTEX SHADER: 5.0
• SOUND CARD: DirectX compatible sound card
• FREE DISK SPACE: 8 GB
• DEDICATED VIDEO RAM: 2048 MB

Okay, after making the changes everything seems to be doing well. My computer no longer has the shutdown issue and I was able to play Mechanicus for about 2 hours with no issue. As @phillpower2 said it seems the issue is my hardware not being up to snuff.

I suppose my issue can count as resolved now, and it seems Speccy has some sort of temperature monitoring portion that I can use to make sure my computer doesn't overheat when I game anymore.

Thanks to everyone for their help, I really appreciate it.
