I finished building my PC recently. when I turn on the monitor when the computer isn’t on, there’s obviously no signal and I see the bouncing logo, but when the computer is on, it says that there is no signal, and that my monitor is going into standby mode, and the display turns off. my gpu seems to be working fine, and I reseated my ram. What should I do?
You should lookup your motherboard manual or something to see what the LEDs mean. From what you say here, it sounds like the POST might be failing due to the CPU. Maybe try reinserting the CPU.
It could also be that it posts but then it should display and let you get into the bios. So not sure. It’s hard to diagnose without more info.
Try reseating your CPU, check the pins to make sure you didn’t bend one. Taking some photos and zooming in can help you get a better look.
According to the manual all of the lights are supposed to turn on briefly.
