Hey guys, I think this is my first time posting here.
I built my own rig about 2 years ago (Specs listed at the end). I have since replaced my PSU once because of a power outage 7 months ago.
The other night I was playing the Witcher 3: Wild Hunt as I have many times before. Later in the night I stretched out my legs while sitting in the chair and accidentally hit the HDMI cord mediocre with my toe causing the picture to go black and the GPU to be un-seated inside the case but systems were still running (could still hear the game and control my character through hearing it). I then did a hard shutdown of my computer and re-seated the GPU this has happened before without booting problems*. I tried starting the computer but the power wouldn't catch til after about 30 seconds, the computer fans and systems seemed to power up after that but my monitor has no signal. I also noticed that since the hard shutdown my Cougar PC case does not light up when the power is turned on which it was doing before the toe incident leading to believe its PSU or MOBO
Things I have tried:
Remove CMOS battery for 1 minute replace and try (no boot)
Reset CMOS and tried another 3v lithium battery (no boot)
I removed my 2 16GB RAM sticks and tried one at a time also cleaning the seating areas of dust (no boot)
I removed my CPU and cleaned the heat sink (made positive CPU power cord was plugged in along with CPU fan, no boot)
I unplugged my power cord and held the power button for 1 minute multiple times (no boot)
I disconnected my unnecessary components, disc drives etc (no boot)
I completely took everything EXCEPT for the motherboard out of the case and re-seated it (no boot)
I have been using it with no problem until i hit the cord with my foot I have also tried new power cords and HDMI cords (No boot)
I turn the computer on, fans come on sounds like its going good but no boot and no case lights
-PSU Corsair CX750M bought from bestbuy 7 months ago
-GPU MSI R9 Gaming 3g
-MOBO GIGABYTE GA 970a-DS3P
-HD WD 1TB
-RAM 2x Ballistix 16gb 1600Mhz 9-9-9-24 1.5V
-AMD FX CPU
Any help would be appreciated I have a feeling I need to replace the PSU or MoBo but I do not have a mobo beeper.
Any help would be GREATLY appreciated.
