AMD Ryzen 9 7900X MSI PRO B650M-A WIFI GSKILL DDR5 6000 - Easy Debug CPU Light - Red RAM Indicator - Yellow Light
Purchased a new system and assembled it myself. It doesn’t boot fully—lights are on but fans spin, motherboard displays red CPU indicator and yellow RAM light. The monitor shows a black screen with nothing visible. I’ve tried various fixes: changed RAM slots, used one RAM at a time, removed and reattached cables to the PSU and CPU/GPU, reset BIOS, checked for bent CPU pins, reapplied thermal paste, loosened the CPU cooler, and even considered flashing BIOS. I also looked into USB flashing but found no clear instructions or support. After several hours, nothing changed. I unplugged the CPU cooler to see if it would heat up and then tried booting from the motherboard graphics. My final thoughts: some Amazon reviews suggest the motherboard or CPU might be faulty. Any suggestions would be appreciated.
Use the MSI BIOS flash tool known as M-Flash. Visit MSI's site to download the most recent BIOS file and follow the steps for M-Flash.
Did you attempt to start it and wait a short while? The first boot on AM5 might take some time.
I've already attempted that. I'm heading to the repair shop tomorrow to check which component is broken. I don't believe there are other options, and I'm out of energy to keep experimenting. I've tried all the troubleshooting steps I thought might help at this stage.
