PC RGB lights activate and fans start, yet the display fails to receive any input.
Not long ago I assembled a PC with these components: CPU Ryzen 5 5600, GPU RTX 3050, 2x 8GB RAM, 700W PSU (EVGA), and a single 512GB Samsung EVO 860. When I powered it on, it shut down immediately, but the RGB and fans activated without any signal. I've done many fixes—rearranging RAM, testing one RAM at a time, changing cables, using different HDMI and cables, switching monitors, etc.—but nothing works. The issue seems to be entirely on the main system. I installed everything correctly and don’t have another machine to test. I’m unsure what might be faulty and don’t know what else to try next. Should I consider replacing the CPU or checking the RAM? Or is there another clue I’m missing?
Is the motherboard updated with the latest BIOS? You'll need 7C56vA9.zip for the 5600 chip.
Have you increased the clock speed of any components? Occasionally adjusting the RAM can cause issues, leading to failure to boot. In such cases, manually shorting the CMOS pins might be necessary. Also, on many current motherboards, taking out the CMOS battery doesn't clear the BIOS settings.
I didn't make any changes, so I thought it always had it. Probably not the problem.
So you managed to get it running, but your initial message wasn't very clear. It seems the device stopped working while it was operating, not just when turned on. I assumed you meant it would turn off after use, but before you noticed issues.
