Hello there,
I upgraded from a 3700x to a 5800x3d today. A simple endeavour, one would assume, but now, 12h later, I am really out of troubleshooting ideas.
Old System: (bought Q3/2019)
CPU: AMD 3700x
Cooler: Be Quiet! Dark Rock 4 Pro
Mainboard: Gigabyte x570 Aorus Ultra (I upgraded the BIOS a couple of months ago to F36d, which is still the newest.)
RAM: 16GB Corsair Vengeance LPX DDR4 PC 3600 CL18 (QVL checked)
Graphics: Gigabyte GTX 1070
PSU: be quiet! STRAIGHT POWER 11 650W
I ran a couple of benchmarks today, just to be able to compare the performance to the new CPU.
Then I disconnected power, upgraded the CPU and tried to boot. But all fans spin on 100%, CPU indicator LED on the mainboard flickers for about 0.5 s then the DRAM LED is constantly lit, monitor is black.
past troubleshooting:
- reseated the CPU (over 10 times now, because I keep ripping it from the socket with the cooler when changing the RAM positions)
- tried lower mounting pressure for the cooler
- borrowed g.skill trident z 4400 CL19 RAM from a friend, but same behavior
- tried to q.flash pro the F36d BIOS a couple of times
- replugged all power cables on the mainboard and the PSU
- tried RAM in dual channel mode, single channel and different slots
- cleared CMOS (unplugged power, took out the battery, waited 15 minutes and bridged the clear CMOS contacts at least 2 times for about 20 s)
Now for the really fun part:
- I reinstalled the old 3700x and the behavior persists, so no functioning PC anymore -.-
It is past 2 o'clock in the morning here (again) and I can't seem to find any other solutions in any forums that work for me. Most of the time they all just had to upgrade their BIOS to fix that problem.
I'm completely out of ideas and would appreciate any straw I could grasp, except "R.I.P. mobo".
Thanks in advance!
