So Let me just get this out of the way first. The PSU is not an issue. It has worked perfectly before this and I tested it with a jumper and it worked beautify plus I have tried all of the different things relating to a PSU issue.
When I boot up the pc everything runs then randomly it shuts off and tried again. The first time it stays on for a longer time. Then the second time it only stays on for about 3 seconds, then it just gets random. Even running everything or the bare minimums gets me the same thing! I can't get a display output on the mobo or the graphics card at all either. Please Help!

Specs:
Core i7-7700k
GTX 1070ti
EVGA 1600w T2 PSU
125gb Kingston SSD
Biostar Motherboard

I have even tried taking out the On/Off switch after clicking but that has seemed to do nothing. I still will have the same issue!

The Weird thing is I just sent the board in for RMA and got a whole new one, So it should not be broken! Never even used!

I did test every everything but the motherboard. It was $70 so I guess I got what I paid for. Thanks! I am about to add 2 more 1070ti's in SLI. I am thinking about an i9 as well. Thanks for your help, guess I am getting another mobo, again...
