Not sure where to post this. Was playing games last night screen froze and though it was just the game but entire computer locked up could do anything powered down the computer and upon restart no display. All fans turn on and run, gpu fans run. Motherboard is showing dram light. Have re installed ram have tried to boot with one stick. Also tried know good ram still have the same light. Reinstalled cpu, same result. Not sure where to go from here.
