My M5A99FX with FX 9590 won't post after small BIOS changes.
After experiencing some freezing issues on high load with my new build, I disabled AMD Turbo Core in BIOS, set Ai Overclock Tuner to D.O.C.P. set the DRAM O.C. Profile from 1600MHz to 1866MHz. I also undervolted the CPU by 50 mV. Having made these adjustments, I clicked Save and Reset, but instead of restarting it went to a blank screen.
I haven't been able to get the PC to post after this incident. The fans and lights still power on, but I get no display signal nor keyboard and mouse power.
I have tried clearing CMOS and reseating all PSU cables, all to no avail. It seems odd that such an adjustment in BIOS would cause CPU or Mobo to die. I updated BIOS a few days ago, but I don't know if I should try to undo the update.
Specs:
Motherboard: ASUS M5A99FX PRO Rev. 2
CPU: AMD FX 9590
PSU: Cooler Master V1000
RAM: Crucial Ballistix 1866MHz 2x8 GB
GPU: MSI GTX 970
CPU cooler: Corsair H100i (AIO)
SSD: Samsung
Also worth noting:
I believe that the original freezing and crashing issues were not caused by the CPU, but the PSU instead. Running the GPU on a seperate PSU while on high load (OCCT PSU Test) seemed to circumvent the problem. I just did the BIOS changes to rule the CPU out.
Any help will be much appreciated, as I am at my wits end!
