Today I turned my computer on, and after a while my 2 monitors went black, and said "no signal detected" and they both didn't turn back on, my computer is still on at this time, so I have to hold the power button on the PC to reboot the computer, I turned it back on and like 9 hours later it did the same thing, I don't know what is going on. Can someone please help me?
 
with a booting system....use hardware monitor...watch your power supply outputs. open the case check that all your fans are moving..even the power supply one. look at windows error log file.

see if it calling out power issue or gpu issue. if it power issue i would start a rma on your power supply if it under warranty. at some point your going to have the part fail where your rig wont turn on. right now the part is starting to fail and it could be the power or the gpu. you have to try your gpu into another pc or try another gpu in your pc if someone you know has a test card to use.

Before, both monitors used to switch off black, then come straight back on again, but now they are staying switched off instead of coming back

And where is the Power supply on the Sensor page?
 
for the hardware info question it under mb under the sensor readings. for the pc issue now. try one monitor at a time see if the onboard video port works if you have one. if not pull the gpu and see if the pc boots to onboard video. if not try another power supply.

if your mb has ports for video. turn off the pc and plug on of the monitors into that port see if it turns on. also

do you have another on of those to use as a test unit to see if your rig has bad power supply. if not you may want to see if there a local shop that can do the testing for you.

So I am plugging one monitor into the motherboard then checking the thing on the sensor page? And where is the the thing you told me to check on the sensor page? I couldn't find what I was looking for?
