My computer becomes unresponsive and the screen displays a "No Signal" message later.
Good day. To clarify my situation, I'm experiencing several issues with my PC. After using it for about an hour, it tends to freeze accompanied by a buzzing noise from the speakers and a black screen displaying "No Signal." Once it powers off, it still runs, but the monitor goes dark without any image. The fans are working normally, though the RGB lights on my RAM become stuck. When I force shut the PC by pressing the power button and then try to restart immediately, it doesn't boot right away. It takes around 30 minutes to an hour before it starts up again, and it works properly once it does.
After that, I have to wait a while before turning it on, but eventually it boots normally again, and the problem recurs.
Here are the details of my PC:
- CPU: AMD Ryzen 5 2600
- Cooler: Thermalright Frozen Notte 240 AIO
- Motherboard: ASUS TUF Gaming B450M PRO II
- Memory: Team Elite Tforce Delta 2x8GB 3200Mhz
- Storage: 1 x Samsung 850 EVO 240gb (boot drive) & 1 x Samsung 970 EVO Plus 1TB (game drive)
- GPU: Asus Dual AMD RX 5600 XT EVO
- PSU: EVGA 600 GD 80+ Gold
I've tried several fixes:
- Reseated the RAM, tested with only one stick and in different slots
- Reseated the CPU
- Reseated the GPU
- Repasted the GPU
- Updated the GPU driver
- Performed stress tests on CPU, GPU, and RAM for 10 minutes without problems
All temperatures are within specifications.
I'm not trying to point fingers at Valorant, but I only noticed this issue after playing it and have been experiencing it even when I'm not. I'm located in a country with limited resources, so I need to double-check which component to replace if necessary. I also don't have any spare parts for troubleshooting.

How much older is this device? I plan to look for a well-made PSU with at least 550W capacity to cover my entire system, hoping the problem doesn’t continue.
Living in a country with limited availability, I need to double-check which component to replace if necessary. I also lack spare parts for repairs.
It’s important to remember that troubleshooting involves following a checklist—sometimes you might spot something obvious, but it’s not always guaranteed.
What BIOS version is installed on your motherboard?
Updated the GPU driver.
Can you explain the process you used to update it? Did you use a third-party application?
Hi. Thank you for your response.
I think my PSU is about three years old now. If someone is open to it, I could ask them to lend me their PSU. I haven’t tried another one yet, but I’m pretty sure this part is probably the cause.
My BIOS seems to be version 3810, and I haven’t updated it since the problem didn’t occur before.
For my GPU, I removed the old driver using DDU in safe mode and then installed the latest driver when I restarted normally.
I've been trying to stress test it but can't recreate this problem through testing. It only occurs when I'm playing games. My mom used it for about four hours straight without any crashes, as she was just watching movies. For a quick update, the PC isn't starting up at all now, even after waiting, which makes me think the GPU might be the issue. I'm still confused until the shop checks it out.
