Issue with MSI B550-A failing to power on completely.
You're facing issues getting power to your MSI B550VC despite fixing the water block, BIOS, and CMOS. Let's explore other possibilities. Have you tried checking the power connectors or ensuring they're securely connected? Also, verify that the CPU is properly seated in the socket and that there are no loose pins. If you're still having trouble, consider using a different power supply or testing with another component to rule out internal issues. Don't forget to consult the motherboard manual for specific power requirements.
First verify your PSU is functioning correctly. Do you have another computer available for testing? You can also employ a basic PSU tester. Regarding the front I/O, even with properly connected cables, a faulty power switch remains possible. The simplest method is to detach the power switch connector and connect the two pins using a metal object (such as a screwdriver or tweezers). If you prefer not to handle anything else, insert the reset switch in its place and activate the reset button to assess. Additionally, confirm all cables and connectors are securely attached. If your debug LEDs are present, inspect them as well.
Water block and fans function after bypassing the PSU with the tester. Attempting to short the power switch pins fails to activate it. No debug indicators appear. The BIOS flash button operates correctly.
