So I turned it off my PC yesterday because of a storm and after it was over I decided to turn it back on. The PC powered on fine but the monitor was not displaying anything and the only visible lights on the setup were all the mouse lights and the power on light on my Corsair 200R case. It's actually done this before but not for this long though. I've already tried to disconnect all unnecessary cables to maybe get the bios to display to no avail. There's also no POST

Try this once unplugged graphic card and do warm booting without graphic card did you plug the cables of computer if not that causes overuse of electricity to the motherboard which make motherboard damage.

Try pulling the power cord and pressing the power button.  Then plug it back in and it should boot up

 

This has happened to my computer several times and this always works.

Hey, do I press it while I pull it out or once it's out? I did the latter and it didn't work.

I appreciate that your trying to help me, but I honestly don't think any of the steps listed could really contribute to helping me with my PC because I just had it off for about 30-60 mins. and It has done this before but for not this extended amount of time. But, thanks anyway for sending the link to me.

On a powercycle, pull the plug then hold the power button down for 30 seconds. Attach the power cord and try booting. How long did you hold down the power button after pulling the plug?

Turning off a computer (or pretty much any electrical device) does not protect it from power anomalies during a storm.  Computers in particular are still very susceptible to surges and spike and other anomalies because when the computer is shutdown, it is still in standby mode and the power supply is still providing +5Vsb standby voltage to several points on the motherboard.

 

The only true way to protect an electrical device during a storm is to unplug it from the wall. The next best way is to use a "good" UPS with AVR, and lastly, use a surge and spike protector. Of course, nothing can protect you from a direct lightning strike - not even unplugging - if the bolt is
determined to get you!

 

Since you tried another monitor/TV and have the same results, you need to swap in another known good power supply and go from there. If you don't have or cannot borrow another PSU from another working computer, you need to have that PSU tested by a professional to make sure it is supply all the necessary voltages.  Unless you have a decent oscilloscope or a true power supply analyzer (and know how to use them and interpret their results), the only way a "normal" user can verify a PSU is working properly is to swap it out with a known good supply.

 

You might also try that monitor on another computer
