A few ideas.
1. Be sure the monitor is on the GPU.
2. No go? Remove the 1060 GPU and use onboard graphics.
3. No go? Make the PC as small as possible. No case, just motherboard and min parts on cardboard and if that fails you are looking at the failed part or parts. It won't tell you if there is some failing PSU, CPU, motherboard but it can get you to the least number of parts to RMA.
Ok, so I have a problem with my PC. In one night I was browsing on Google and then suddenly my PC freezes. I restarted it from the power button from the PSU and then I turn it on, he worked. After let's say 30min the PC freezes again but this time when I tried to reopen it , the components were on but the PC didn't give signal to monitors. I was at a local PC repair shop and they tell me that the MOBO is the issue (I had some bend socket pins), but the things is that my PC worked for 1 year with that 2-3 bend pins. I gave the MOBO to the warranty and now I got a new one, but I still have the same problem, no signal. Before all this, my PC when turned on I could hear how is booting, but now is just turning on , without doing anything.
Recently I bought another RAM , and then I boost both RAMS to 2666. But I didn't have any problems, and after 2 weeks my pc isn't working anymore (no signal) The last thing I did I used a stick to reactivate the key (Windows), could be this from a virus ? I used the same stick in past but I didn't have any problems. (Not sure if this is the problem)
I tried all the ways to fix it
-One RAM stick
-Unplug the power cord and hold the power button for 30sec-1min
-Remove the CMOS Battery for a night,(ik also is good for only 10 min)
-Tried without GPU, RAM , HDD , SDD .
-I clean even the PC.
