FIX | PC Turning On But No Signal On Display, Keyboard and Mouse

solution: 1:44 - 3:22

In case my solution does not work then I'd suggest you to assemble your pc outside of the case. That's how I diagnosed my reset wire cable problem. If your pc boots outside of case then you can diagnose what is exactly causing the problem. A technician here told me that my mobo was dead but somehow I made my mind to try assembling it outside of the case a night before I was about to go to RMA my mobo and surprisingly it worked fine outside of the case! There I came to know that my mobo was ok but something related to my case is causing the problem and turned out the reset wire of the case was causing it. Still I learned it the hard way as I had already bought a new PSU thinking my PSU was causing the issue.

my rig:
case - corsair 110r
mobo - msi b450 pro vdh max
cpu - r5 3600
ram - 16gb x 2 corsair
gpu - zotac 1660 super
primary storage - ssd wd 500gb
secondary storage - hdd wd 1tb
power supply - corsair rm750e
