MSI extended PWM heatsink and enhanced circuit design ensures even high-end processors to run in full speed.Ĭontrol watercooling pump speeds for best flow and noise control. Preminum 7W/mK thermal pad covered both MOSFET and chokes, provides better heat transfer to the heatsink.
Protecting VGA cards against bending and EMI for better performance, stability and strength. Highest quality component digital power IC makes sure your system runs smoothly under the most extreme conditions.
Reverted back to the old build which now doesn't work.Simply use a USB key to flash any BIOS within seconds, without installing a CPU, memory or graphics card.Ĭombining premium layout design, that is ready for unleashing the maximum performance.Īn enhanced PCB design improves heat dissipation and performance reliability. Used two different motherboards (same model). 
Verifying power connections (8-pin CPU, 24-pin ATX, 2x 8-pin PCIE). Reseating one and two sticks of RAM for all four sticks owned in all four slots in both motherboards. Resetting BIOS (grounding pins and removing CMOS battery). USB BIOS flashback using all four USB drives I own with the three latest versions. Troubleshooting: Here's a list of things I've tried so far: So after two full days of trying to debug and getting new hardware to test with, I'm about completely out of ideas on what the issue could be. As for the GPU, I only cleaned off the dust (using a q-tip and a microfiber rag) from the fans and the heatsink behind them. However, the PSU was never removed from the case except for about 20 minutes before this post when I was checking that the semi-module cables (8-pin CPU and PCIE power cables) were securely in it. Since it now doesn't work with a previous build that was 100% working two days ago, my assumption is that either the new motherboard damaged something or somehow the GPU and PSU (the only two components shared between all three attempted builds) have been damaged over this time. Instead of the debug LEDs, however, when I tried to boot it the fans on the GPU/PSU/CPU would just spin for half a second or so and then stop and then continue doing that until I shut it off. However, once I did that build wasn't working either. Since the original build was working two days ago, I decided to plug that all back in for now. Yet again, the issue stayed the same (though the CPU LED was on for a while at first before it went to the DRAM LED). #MSI B550 A PRO CPU LED UPDATE#
So I bought a 3600 assuming it was a BIOS version issue with the 5600x and hoping it would be able to boot with the 3600 and then I could update the BIOS. The issue still persisted so I got a second motherboard (same model) assuming the first one was not working. Since the debug LED was on the DRAM label, I decided to grab some new RAM (the Crucial one listed above) to try that out. I spent about 12 hours trying four different USB sticks with the latest three versions of the BIOS using the USB BIOS flashback feature, but the on-board red LED would just continuously blink forever until I shut it off (the longest I waited was about 5 hours while I slept). The motherboard's EZ Debug showed either the CPU or DRAM LEDs and there was no display on the monitor.
Built the new computer but it wouldn't POST. I kept the GPU and PSU from the old build as they were working just fine for my needs. Longer Version: Upgrading from a 6 year-old build, I ordered a 5600x, MSI MAG B550 Tomahawk, and the 32GB G.Skill RAM.
