Okey my problem is that when i try to start my computer the monitor wont start, it stays black and nothing happens. I have tried with another monitor but the same problem there, and when i tried my monitor on my laptop it worked in the beginning so it should be something with the hardware. Everything is brand new except for the RAM. I hade exactly the same problem with my other older computer but i had several problems with that computer, but i say again, The CPU, GPU, PSU and the motherboard are all brand new. I really hope someone can help me now cause it's really important that i have a working computer.
