Question Computer restarts randomly ?

[yoonation]

Hello everyone,

I have been having this issue for a while and I cannot solve this issue which has been quite frustrating. When I play league of legends, my computer restarts randomly. The RBG stays on and it just restarts. Usually if it happens during one session, it doesn`t happen again. It also happens when I watch netflix sometimes but rarely happens when I am watching videos on other platforms such as Youtube. When i have a lot of tabs opened up and multitasking, it crashes sometimes as well. It happens the most consistently when I play league but there are times where it wont happen for a few sessions and once it occurs, it will start to happen more consistently.

Other weird thing that happens is when i shut town my computer, the RGB on the fans stay on. Only the fans and not for other parts of the system. I need to turn off my PSU completely and after about 5 seconds the RGB turns off. I have ryzen 5 5600g with aorus b550m pro-p with 16gbs of ram. I want to install a gpu now that prices are acceptable but without figuring out what the issue is I can`t. I also am not commited to just completely rebuilding everything since I do not game too much. I have tested RAM, CPU, and APU, but it only crashed one time during Heaven benchmark.

What I have tried so far:
- took it to a shop (where they tried reformatting windows and also factory resetting)
- called in someone to check it out where they said they think its PSU issue, so i replaced PSU to a high 750W Gold
-BIOs update
-updated drivers

Here is a summary of my efforts with chat gpt.

PLEASE SOMEONE HELPPPP!!!!

Summary of Issues and Troubleshooting​

---

Primary Issues​

1. Random System Shutdowns:
   • Occur especially under load (e.g., gaming, Netflix, League of Legends, Heaven benchmark).
   • System sometimes appears on but with no display, requiring manual PSU shutdown.
   • Event ID 41 in Event Viewer (kernel power failure).
   • Screen tearing, freezing, and buzzing sounds before crashes.
2. RGB Issues:
   • Motherboard RGB does not sync or respond to color adjustments.
   • Fans’ RGB stays on after the system shuts down and only turns off when the PSU is manually powered off.

Troubleshooting Steps Performed​

Power Supply (PSU)​

• Action: Replaced the PSU.
• Result: Did not resolve the random shutdowns.

Memory (RAM)​

• Action: Ran MemTest86; no errors found.
• Result: RAM is unlikely the cause.

CPU and GPU​

• Action:
  • Ran Cinebench (CPU stress test) successfully without crashes.
  • Ran Heaven benchmark (GPU stress test), which triggered shutdowns.
• Result: GPU or GPU-related power delivery may be the issue.

RGB and Power Settings​

• Observed RGB issues(unsynced RGB, fan RGB staying on after shutdown):
  • Motherboard's RGB does not sync properly.
  • RGB Fusion software seems unreliable.
  • RGB fans remain on after the PC shuts down unless the PSU is switched off.
• Result: Indicates possible power management or motherboard hardware issues.

Stress Testing​

• GPU: Fails during stress tests (e.g., Heaven benchmark), pointing to GPU or power delivery issues.
• CPU: Stable under Cinebench, suggesting no direct CPU problems.
• Result: Shutdowns correlate with GPU-heavy workloads.

Welcome to the forums, newcomer!

When posting a thread of troubleshooting nature, it's customary to include your full system's specs. Please list the specs to your build like so:
CPU:
CPU cooler:
Motherboard:
Ram:
SSD/HDD:
GPU:
PSU:
Chassis:
OS:
Monitor:
include the age of the PSU apart from it's make and model. BIOS version for your motherboard at this moment of time.

You might want to include all parts that you've used to troubleshoot your system.
