I just recently built my first PC but it doesn't seem to start. I am Using the Gigabyte H170 Gaming 3 motherboard, intel core i5 7500 Processor and 2x Crucial 4GB DDR4 2400 UDIMM memory. My graphics card is expected to arrive in two weeks, so I decided to install the operating system and transfer my data before that. But it doesn't start, which doesn't make sense to me, since the processor does have integrated graphics. When I turn on my PC The fans start spinning the motherboard lights up, and I can hear my hard drive running. But about 20 seconds later it just turns off. I also don't have any feed on the monitor. I have tested my monitor and vga cable, I have swapped my ram into different slots, and have carefully checked my wiring. I also have a Corsaire VS 450w power supply, so that also shouldn't be the problem. Should I wait on my graphics card or is my CPU faulty? Or could there be any other problem that I did not think about?
