I am wondering if I can get your opinions. Here is the story. I have a H170 pro gaming motherboard. I have an i5 6600 cpu and 16 gb of ram. I build the computer and after a month I decided to upgrade to 750 watt power supply. I installed the psu and then went to go turn it on, it did not turn on. So I tested it and it tested fine on my psu tester. So then I thought maybe the amp is bad. I then installed my old own that I know works and the computer did not turn on. So I knew the 750 psu works. I then put just the psu 24 and 8 pin connector in. I put the cpu and the cpu fan in. I then put in my ram. That is all. I also just hooked up the power switch and went to go turn it on and nothing happened. I then connected all the other switch wires like hdd led and stuff like that. Same thing happened. So I called up asus and they said it is still under warranty. So I sent it to them. I got it back and still does not work. They said they did do some repairs on it and I even saw they sent me a different cpu cover too. I made sure it was the same board and it was. I sent it in 3 more times after that. So now I am about to send it in for the fifth time. They sent me shipping labels every time except the first. That is fine. I checked my standoffs but there all in place like the orginally were. So can't be standoff. I tried removing the bios battery and that did not work. I tried to cross the leads with a screw driver and that did not work. What happened is I see the lights on the board show up but when I hit the switch, nothing happens. The fan doesn't spin, nothing. This happens every time. This has been going on for 2 months. Do you guys think I should keep fighting after sending it in the 5th time? They said they have tested it and it works fine for them. I doubt that. Keep fighting or accept lost? What are your experiences with asus repair? I have looked at the cpu socket to make sure no bent pins and found nothing. I tried bread boarding, nothing. What should I check or do?
