Computer turns on yet monitors say no signal

So, earlier today my monitors randomly went black. The PC was still on but it was clear that it had either crashed or froze, since it didn’t respond to anything. I turned my PC's power on and off and since then I’ve been getting no signal on both displayports and hdmi cables on both my monitors. The PC turns on like usual - fans spinning, no unusual noise - yet my monitors can’t get a signal. I’ve tried DVI, displayports and hdmi cables on both a rtx 2060 card and two different 970s, so I’m confident its not a GPU issue.

If anyone has an idea of what could be causing this please reach out. Would be much appreciated.

Hi @mikebach,

What is the make and model number of the PC or the motherboard if a custom build?

Can you get into BIOS with a display?

完成的

I have a Z170A MSI motherboard with an intel graphics card, 16gb of ram, i-7 6700k, rtx 2060 and a cooler master v1000 PSU.

After removing the gaming GPUs completely I managed to get a signal to my 1080p monitor through an hdmi cable from the motherboard's intel graphics card. However, the computer is still struggling since there are green, flickering pixels on the monitor. I also tried plugging the hdmi cable into my 4k monitor but there I get no signal. I'm clearly not very smart about this sort of stuff but from what I've read online I'm thinking that it's my PSU that is struggling to provide enough power. I've tried reseating ram, disconnecting various other stuff, resetting the cmos through BIOS and by removing it and still nothing.

完成的

If your monitor is displaying "No Input Signal," there is no image displayed from your PC to your monitor. Unplug the cable running from your monitor to your PC and plug it back in, making sure the connection is firm. The most common cause of this error is a loose cable.

Otherwise kindly check out more methods in the post that you cna just try to fix the issue on your own.
