I recently built a new PC with the following specifications:

CPU: AMD Ryzen 5 5600 3.5 GHz 6-Core Processor
CPU Cooler: ID-COOLING SE-224-XTS 70 CFM CPU Cooler
Motherboard: Asus PRIME B550M-A WIFI II Micro ATX AM4
RAM: Corsair Vengeance RGB Pro 16 GB (2 x 8 GB) DDR4-3200 CL16
Storage: ADATA Legend 800 1 TB M.2-2280 PCIe 4.0 X4 NVME SSD
GPU: ASRock Steel Legend OC Radeon RX 7600 8 GB
Case: NZXT H5 Flow RGB ATX Mid Tower
Power Supply: CoolMax ZX-600 600 W 80+ Certified ATX

After initially setting up the PC, it booted successfully into the BIOS. I made adjustments to the clock settings and saved them. However, the next day when I attempted to boot the PC again, it powers on (all RGB lights and keyboard are functional), but there is no display signal on the monitor. The monitor reports "no signal" despite being connected to the GPU (Radeon RX 7600) via HDMI.

Troubleshooting Steps Taken:

I have reseated the GPU and RAM modules multiple times to ensure they are properly connected.
I cleared the CMOS by removing the battery and shorting the CMOS reset pins.
I tested with a single RAM stick in different slots and tried different combinations.
All cables and connections have been checked for proper seating and functionality.
I have confirmed that the monitor and HDMI cable are functional by testing with another device.

Despite these efforts, the issue persists, and I am seeking advice on further troubleshooting steps or potential solutions to resolve the lack of display signal upon booting.

Any assistance or insights would be greatly appreciated. Thank you!

If you have on board graphics for you cpu, I'd suggest try booting it up that way & see what happens. Maybe your power supply can support the build?

Unplug everything except the display cable and see if you can at least reach a POST screen - it should hopefully tell you that you need a keyboard plugged in.

Try going down to a single stick of RAM and resetting your BIOS settings as the memory profile could be causing an instability when using XMP (or whatever the AMD version is called that I can never remember).

Cheap PSU and overclocking anything is a yikes move.

Remove everything that is unnecessary, reset the CMOS, use a different display cable and plug it into a different output on GPU and input on monitor. If you still get no display at all after that, try another PSU because that's more than likely your issue, and hopefully the only issue if it is that.
