THis board was bought used along with A10 7700K, 16gb of Kingston ram, and Sapphire HD6850 from the IT manager at my college.
Installed in case with CoolerMaster 600 Elite ps.
Booted fine but only 8gb of ram report as active though all identified. I removed the two sticks that did not show as active.
Machine ran fine for about 2 months then started random shut downs. CPU temp was near 70 F under load. Let it cool then tried to reboot. I had to move the ram to the opposite channel slots before it would boot but then worked fine. About two weeks later shut down again. On restart I found only 4gb reporting as active. I tried reseating the ram, it posted to BIOS then shut down. Now I only get power to fans but no beeps, no post, and no video of any sort.
Bench tested the board and got black screen with vid card and on-board. I got weird results with ram. Some sticks set off beep codes indicating problem (rapid non-stop beep). Others did not produce any beeps but did not allow boot either. I have no other ram to check the slots and it may be a while before I can get any (We are all under house quarantine here on Luzon, Philippines). I also tested with another PS( FSP 500w) and got same results.
Vid card tested fine on another board, as did processor and power supplies.
Since I had to leave my shop equipment when I moved, I have nothing in the way of testing gear.
I realize the mobo or ram is the problem but are there any other avenues to check.
Thanks in advance,
Bill
