I'm not certain what's wrong with your PC...
Hello,
It's been four years since I built my own gaming PC. It was my first build, so I might have bought some parts and made a few mistakes. Now let's move forward.
Over these months, I've noticed my PC frequently encountered blue screen crashes. Despite having genuine Windows and all games installed, I couldn't identify the cause. Eventually, the blue screen errors would resolve themselves, but later on, my PC would shut down during operation, and after a few days it would fail to start altogether. When I tried to power it on, nothing happened. Sometimes it would boot up unexpectedly with just one click.
Now, it doesn't even turn on at all when I press the power button. I suspect the problem might be with the PSU—it could be damaged or fused. Another confusing point is that my RGB mouse and headset lights work perfectly, but the PC's power switch seems to stop working while the components still light up. Could the PSU be the issue?
I was wondering if the PSU is struggling to provide enough power to boot the system, even though it can illuminate parts like the RGB lights. My motherboard, RAM, storage, processor, and graphics card are all in good condition. Please share your thoughts.
ATX power supplies create a 5VSB rail that stays active when connected to AC power. Based on your motherboard, certain USB ports may stay lit even when not in use. This feature helps charge batteries in external devices while the computer is in standby. You might notice LEDs lighting up on connected peripherals. If you're facing issues, the problem could lie with the PSU itself. Alternatively, it might be a faulty CPU, RAM, or graphics card. Trying to replace each component one by one can be time-consuming and costly. Troubleshooting can be both expensive and frustrating. I think the PSU is a likely cause. Do you have a spare unit you could borrow or use from another system?
It's evident why certain parts are lighting up. But as you mentioned, swapping everything would be very costly for me and I can't borrow or I don't have any spare parts. I think it would be best to purchase a new PSU. I'm almost certain the PSU is the issue because if the CPU were dead, the BIOS would indicate CPU failures too. I also have two 8GB RAM sticks. I attempted to start up using only one channel with each RAM stick separately. I don't have a graphics card; I use Vega 11 graphics from Rayen 2400G.
Checking each RAM module individually to see if it operated at the standard rate or with XMP activation.
2 to 3 days prior, it was running on XMP from the start. It's also important to mention that when my PC was functioning properly, I once removed the RAM stick for cleaning and later reinstalled it incorrectly. During boot-up, my PC emitted beeps suggesting a RAM issue. After installing it correctly, there were no beeps and it started successfully. If there was a RAM problem before, I would have heard those beeps, but I haven't experienced any now.
The only reason I bring it up is due to past problems with RAM on Ryzen systems, so if you're experiencing instability, my first step is usually to check if the RAM runs at its default speed of 2133Mhz and see if that helps. I think the issue might be from it being installed incorrectly—perhaps in the wrong slot?
The random shutdowns and failure to start clearly indicate a power supply issue. It's challenging to confirm the exact problem without checking each part.
Because my PC was acting up suddenly, I had to swap out the RAM and that didn’t help. It turned out to be the new PSU. You can usually return items within 14 days or more. The PSU is essential—it powers everything in the computer. If you’re planning to get a GPU, it might be wise to order the PSU now so you’re ready! The RX 6600XT needs at least 500 watts, so a PSU in the range of 650W to 750W should work well.
