Screen glitches out whenever my desktop gets bumped or the desk shakes.

I have this custom PC that I built and whenever I accidentally bump it (not even very hard at all) or move it while it is on the screen glitches and has like red pixels all over it for a second and sometimes freezes. Does this happen to anyone else and does anyone know how to fix it? I think it may entirely be that the GPU is not entirely seated correctly or that it's just old and is fragile.

 

PC Specs:

Ryzen 3 1200 (stock speeds)

8gb 2400mhz ddr4 (G.Skill Aegis)

ASRock AB350M Pro 4 motherboard

250gb HDD (7200RPM Boot Drive)

1tb WD Blue 7200 RPM

GTX 750 1GB (Maybe the main problem)

Corsair CX450 80+ Bronze PSU

DIYPC BG-01 Case

It most probably is the display cable, but just to make sure re-seat the GPU in the PCI-e slot.

Thanks I will also switch out the HDMI Cable for a different one I have lying around.

Sound like an issue with the port or the cable itself
