Hello guys
I currently have an ASUS M5A99x Evo motherboard. Recently when I powered on my system it failed to POST. The DRAM_LED is solid red. I tried using the MEM_OK button to no avail. I tried every possible configuration of RAM including testing 1 stick in the correct single slot config (as per the manual) I then tested the RAM in another machine with no issues. The BIOS is up to date. (as was required for my CPU which was installed 2 months ago)

Things I have tried:
Resetting CMOS
MEM_OK button (the light then flashes at 1 speed then another then returns solid red)
Reseating the RAM testing 1 stick at a time
Cleaning the contacts on the RAM
Loosening motherboard mounting screws (as per another TH thread)
Confirmed RAM is functional
Verified all ATX power cables are secure
Moved the jumper settings
I even removed every component and put it all back in


Full specs:
ASUS M5A99x Evo motherboard
AMD FX 9590 CPU
Radeon R9 390
Corsair 1000W PSU
Mushkin Chronos 240 GB SSD
Antec 300 Chassis

I think I might need a new board, this one is past warranty at ~3.5 years, but before I give up I thought I'd fish for ideas.

Asus M5A99X EVO and Asus M5A99X EVO R2.0 both are listed as having no support for the 220 Watt TDP FX 9590.

I don't know where you got the information about the BIOS ,"as was required for my CPU". I suggest checking the published CPU Support List.

The heat from that processor likely has damaged the current motherboard.

Whoops, forgot to mention RAM is: CORSAIR XMS3 8GB (2 x 4GB) 240-Pin DDR3 SDRAM DDR3 1600mhz
Pretty sure this is NOT on the QVL for the board, but this RAM was functional in this system previously by using MEM_OK button.

This was an early AM3+ motherboard, the BIOS it was shipped with did not support FX processors. (These threads were a dime a dozen back when FX series were released since you could buy AM3+ sockets well before you could buy FX series processors: http://www.tomshardware.com/answers/id-2217258/amd-8320-post.html)

You are correct that it was not the best idea to put a 9590 in this board as the board does not support the 220W TDP. I bought the board years ago and decided to upgrade my CPU a few months back. This seems odd to me that it functioned perfectly fine for 3 months before this happened. Using CPUID HWMonitor I never recorded a temperature above 45C and usually saw 40C even while under load.
