This is my first time building a computer, and I'm not really familiar with the process . My friend was helping me to put this all together. I had to press really hard to get the CPU heatsink to latch correctly, which had me worried.
It does not boot. The fans all turn on and the leds on the case light up. My friend tried the GPU in his computer, and it booted up correctly. So, I don't think that is the issue. Any suggestions for what I should try?
