So my motherboards dram led light came on a week ago and won’t boot. I’ve tried changing the ram, clearing cmos, resetting jumpers, reseating my graphics card, trying a new cpu, trying a new psu, and i can almost 100% confirm that my mobo is the problem, but can anyone confirm this or help me troubleshoot before I buy a new mobo, cpu and new ram? Thanks!!
Specs:
Asus tuf x58 mobo
Intel Xeon x5675 on a ID-Cooling aura flow 240x @4.5 ghz, but cleared cmos so the overclock shouldn’t be applied anymore
Gtx 1060 6gb windforce oc edition
800w gold plus certified from apivia (just got this in the mail)
And viper 16gb ram @ 1765 MHz I think.
