Hi what happens if you take the RAM and GPU out and turn the system on? how many beeps do you get (if any)
If you get three beeps then put the RAM in and turn on, how many beeps do you get? You should get 2...if so then you will need to test another GPU as it would appear MBD and CPU and RAM are wrking
Thanks for your attention.
If i start the mobo with only the cpu and cpu fans; no beep.
(i try that with the mobo out of the tower, on a plastic surface)
I think the mobo is dead.
I would try an other today.
I will tell you the result.
I had this issue, thought the Mobo was dead. Tried another PSU and it works fine. I'd suggest you try that
same here with a TX650 v2, RMA in process, AX750 works fine
its your PSU, either incompatible or faulty
theres a link in another post about Intel verified PSU's, and surprisingly the TX650v2 is listed
Its the power supply, I have the same problem with every (three) CMPSU-750TXV2 power supply I tried. the older version works fine CMPSU-750TX.
I'm not sure if the DP67BG is just hyper sensitive or if there is truly a problem with the power supplies. I have a support ticket opened with both Corsair and Intel.
