PC stops during gameplay – possible faulty power supply unit.
PC stops during gameplay – possible faulty power supply unit.
Hey there, everyone. My friend recently got a new PC last year, but it’s been having a lot of issues lately. Games are crashing, the system shuts down unexpectedly, front USB ports aren’t working, the start menu closes abruptly, and keyboard input is all over the place. After reinstalling Windows 10, most of these problems disappeared, and we discovered the front USBs aren’t functioning properly. It seems the keyboard works fine on the rear ports, which suggests a problem with the case’s ports or possibly insufficient power from the PSU. Unfortunately, it’s too late to return the PC for a full refund—it was purchased from a reputable custom seller in Java at a very reasonable price of $1000.
I’m not comfortable with the PSU, RAM, or SSD choices since I’m unfamiliar with those brands. This makes me suspect the power supply unit (or maybe a defective motherboard) is the culprit. The best we can do right now is troubleshoot further and possibly replace the faulty components.
The main problem she’s facing is that when running demanding games like Genshin Impact at high settings, the PC shuts down completely. I can replicate this issue consistently—at 144 FPS it crashes in a minute, but at 60 FPS it runs smoothly for hours. This points to a potential power delivery issue with the graphics card or PSU. The temperatures checked out, so overheating isn’t likely, though I can share logs if that helps.
Usually, I’d try swapping parts one by one to find the cause, but we’re apart and she doesn’t know how to replace components herself. I can only guide her remotely and help identify the exact issue. If you could point this out via logs or remote assistance, it would really help.
TL;DR: How can I remotely pinpoint the faulty part so replacing it fixes everything? Thanks for your help! Pogge
The chip and board are working well in general. Personally, I wouldn’t have chosen that specific board with that particular chip, but it’s not a major issue either. For testing purposes, do you have another GPU available? That would allow me to try it with something less power-hungry. If needed, I might need to adjust the PSU rating just in case. I’m not sure about the power consumption of the 3070ti—look it up and calculate if it fits. Also, since everything is packed into a compact design, make sure there’s sufficient airflow around it. Sensors can give wrong readings and the tools used to monitor them might misinterpret data if the temperature rises. Usually, keeping temperatures below 90°C for both CPU and GPU is acceptable, especially when running under load. Check all these factors and see your conclusion.
Thank you for your response! As discussed earlier, I can't try a different GPU because it's far away from me. I might ask her to take it out so we could test the built-in one, though I'd hope it would function properly—especially in low FPS settings. The crashes seem linked to more demanding games. From what I recall, the GPU temps stayed around 80°C max, while the CPU temps were even lower, and overall temperatures appeared normal.
It's a good decision, though I'm not sure if we've already attempted that. I'll give it another shot and update the thread. Any additional ideas would be appreciated!
Update: We've tested the Studio Graphics drivers and they seem more reliable at the moment. Thanks!
Hi! I'm the Customer Success Manager at Jawa. Just send me a direct message and I'll do my best to assist you.
This wasn't a request made through Jawa.gg. It came from a seller on our own site, even though it was bought from their individual platform. I suggested the customer visit the seller's official website, but unfortunately we can't intervene since the purchase didn't go through our system.
