It seems like you're trying to figure out what's going on with your new computer. You think it might be a fresh build, but if you're having trouble getting a signal or the system isn't booting properly, that usually means something's wrong with the power-on self-test and video output.
It might stem from various issues such as a dead CPU, motherboard, GPU, PSU, or even minor problems like a faulty cable. The situation could also involve something small like a bad connection or incorrect power supply. Could you share more about your PC model and its fan behavior?
We can only provide general advice unless you share more details about your PC—such as its parts, input/output methods, and previous troubleshooting steps. Possible causes include: incorrect monitor settings, wrong video cable connection, power issues, dead GPU, or insufficient power supply. If no GPU is present but the monitor is connected to the motherboard, the CPU might lack integrated graphics.

Connected to the GPU, monitor input uses DP. I've tested HDMI but nothing else works. BIOS appears when I enter it, but no fans are running and the GPU spins. If needed, I'll take a picture after school as soon as possible.
Only one open window was created after installation; subsequent attempts fail to appear.
