i built a computer and the monitor says "no signal detected" what do i do?

If you just put this together it isnt the monitor and may not be the video card. Take everything out but the processor, memory and video card. If you have onboard video use that instead of a video card. Unhook the front usb and audio if you connected it. You want just enough hooked up to see if it works. Then if you get it to post on a monitor, you put everything in one piece at the time to see whats causing the problem. Just take it slow and you will get it to work.

The problem is not the monitor. There is no signal detected from the pc. So you should get into that

if you built the computer then you should know what to check for this. My suggestion is to check the drive cables motherboard and video cards. If all is connected and still dosent work take it to a shop or google it online.

check if your video card is in all the way, and if you have onboard video check if thats plugged in all the way. if nothing works make sure your graphics card has a 6pin pcie plug going from the power supply to it (IF IT NEEDS IT!!) otherwise its probably a bad gpu

plug it in lawlll
