Hello again.
My pc wont post, i dont know what to do, when i turn it on everything seems to work fine except the display which says no signal, i tried other monitor and it didnt work, pc can work for hours but the display just doesnt work. The problem happened 2 months ago when i switched my cpu and thermal paste then it just stopped working correctly after i restarted the pc 4 times. I tried changing cpu cooler yet it changes nothing. I noticrd that also led lights on my keyboard and headphones work but on mouse they dont all tho i cant recall if the lights on mouse were turning on at the time of turning on the pc. I also tried to press caps lock on mx keyboard to see if it will work but it doesnt which im assuming means pc failed to post?
