PC experiences sudden jolts and stops unexpectedly.
PC experiences sudden jolts and stops unexpectedly.
Hello, I hope this is the correct location to ask.
Last week, when I started my PC, it displayed unusual behavior. I wasn’t able to find an exact match of the case I had seen before, so I wasn’t sure what was happening. To note, the week before this incident there were several power outages in my neighborhood, but such events had occurred occasionally for years.
A short time after the PC launched Windows, it experienced a strong electrical surge, which I felt through my metal earphones. The display also flickered briefly, yet the monitor remained on.
Hours later, the screen went completely dark, but this time I wasn’t sure if the shock was still present since I hadn’t used my metal earphones. I removed the components from the case and ran the system bare for about half a day to test, but nothing changed. Everything seemed fine afterward.
I played a game of CS2 and it suddenly shut down unexpectedly. After opening the case, I tried booting by short-circuiting the power button and it worked normally. Once I put the case back on, I played six matches of CS2 without any issues. The temperature was high, but the peak never reached 90 degrees, so I don’t think heat is the problem.
My guess is that a component was damaged, but I can’t identify which one. Because it happens so randomly, I can’t recreate the situation to eliminate a faulty part. If you have any suggestions, please let me know.
Here’s a summary of the components and their ages:
1. Ryzen 5 5600 (<1 y.o)
2. Gigabyte A320M-S2H-V2 (>5 y.o)
3. HyperX Fury 16x2GB (<1y.o)
4. Sapphire RX6600 (>2 y.o)
5. Adata SX8200 Pro (~1 y.o)
6. Corsair SF450 (>2 y.o)
7. Silverstone SG11 (>5 y.o)
I’ve been using a metal earphone and an aluminum keyboard for five years. My latest addition to the setup includes USB and HDMI extension cables for my display tablet, which I installed about a month ago. The case’s power button is now very difficult to press; it requires holding it for a long time and applying significant force to activate it. Any assistance would be greatly appreciated.
Best regards!
The temperature was quite high but the peak never reached 90 degrees, so I don't believe it's a temperature problem. This is GPU or CPU temperature? Which application were you using to track your temps?
You might want to get another SFX unit from Corsair SF450 (older models), ensuring it has at least 450W for the whole system.
My power button is hard to press now; I have to hold it for a long time and apply a strong force to make it work.
Does this problem occur when you short the positive/negative pins on the motherboard?
It looks like a grounding issue. You should first reach out to a certified electrician to check if the wiring in your home is damaged, then ask them to inspect whether the main lines entering your house have any crossings.
I mentioned a grounding problem because of the shock you experienced, not just the buzzing sound in your ears.
1. Both units are around 80 with a rating below 90, these are during CS2 operation.
2. I possess a 500W PSU from RMA that is new and will attempt to use it if needed.
3. No, I short the power pin and it stops right away. I tried removing the housing and saw the actual button on the PCB has some space; I need to press it precisely.
4. At first I believed so, but I’m not sure. My setup and other metal components don’t cause damage under normal use, only my earphones did when the PC briefly shut down. My brother uses the same connection and has no issues.
