Hello, I am having trouble with my newly built system.

The PC ran fine for a hour, I managed to install windows 10 Pro to the SSD, after restarting to finalize windows installation system refused to post, screen went black.

I assumed the problem was my old Gigabyte GTX 670 and swapped it out to my newer card MSI GTX 1060 6GT OC, system still refused to post.

New system specs -
Motherboard: Asrock H270 Pro4
PSU:Coolermaster B600 V2
CPU:Intel i5 7600K
RAM: Crucial 4GB x2 DDR4 2400 MHz
Cooler: Idcooling Frostflow 240L - W

I tried other PCI express slots on both of the motherboards, and with both my old PSU and the new one.
Should I assume that the PSU killed the PCI express slots on my old motherboard too? I can't test this, no more GPU's that previously worked...

Now I am sitting here with 2 dead cards and a dead motherboard, I am assuming that the Coolermaster PSU fried the components.

I have tried both GPU's to my old system, black screen and fans spinning on both.
Should I RMA the PSU, and hope for the best on GPU's and motherboard?
I am not sure about the damage on CPU and RAM, I can only hope that they didn't die too.
The ssd is fine, tested it with my old system.

I am aware that if the PSU fried the motherboard and GPU's there is little to no chance get my GPU's and motherboard fixed via warranty, since it wasn't their product that failed.

All the problems started after restart button was pressed, all was smooth sailing before that.

I tried to include everything, hopefully this helps with the trouble shooting.

For the new PC ( the i5 7600K), do you have other air cooler to try? If the PC will not boot without the boot device and RAM, that means either the MB or cpu has problem, and usually the problem is from the MB.

Try to remove the GPU and clear the CMOS by the jumper first. Then using onboard iGPU to boot the PC to see the PC works or not. If it does boot you know at least the PC is fine, the only problem related to either the PSU or GPU.

The CM b600v2 is not the good PSU, you should return it anyway. Buy other good brand PSU, more info: How to buy a PSU http://www.tomshardware.com/t/power-supplies/

Also when you switch the GPU in either old or new system, do you use DDU to unstall the old GPU driver first? http://www.guru3d.com/files-details/display-driver-uninstaller-download.html

I have now reset my CMOS on the old system and cleaned my drivers with DDU, the GPU started working again! one less pc to trouble shoot.

The new system seems to power on for 3-6 seconds and shuts down after that, and restarts again to stay on until it is manually shut down, I tried to reset CMOS on that system too, it didn't do anything.

Nothing on onboard video.

I might take the whole system apart and try to power it on with only CPU attached to the motherboard.

I now have taken the whole system apart -

Still not posting, I tried without RAM too, still powering the system on for 3-6 seconds, shutting down and after that the system stays on.
