I am having a somewhat similar and very frustrating moment w my build as well. The tomahawk 450b max w 3600 ryzen shows “white” for about 3 seconds and then goes red. Here is what I have done:
1. Went over each connection point, power cable. Started w the (8?) pin power to the cpu, then the sata to the hard drive, each fan power cord which all are running, and double checked the graphics card power.
2.went down the book trouble shooting and the internets list of “what did you do wrong?!? What’s wrong w you?!?” List. This includes:
-reinserting graphics card And power cord
-changing the sata cord to different ports for my hard drive.
-changing my ram slots as suggested. This entails using only one 8gb in slot 2 (dimmA2).
- changing my hdmi to standard monitor plug in.
I worried that I put in the processor the wrong way, but I triple checked my placement epics and used the triangle for mapping.
Someone please help. I don’t think I did anything amateur like static fried anything; really paranoid and methodical.
Last note:the motherboard has4 red led lights on it labeled “cpu, ram,vga,boot”. After unhappy red lighting of the motherboard and a beep, it lights up red on cpu, NOTHING on ram, then vga and boot. Again, please help.
