So over the past 5 months every time I would bump my desk my monitor would black screen and I would have to restart my computer and unplug the hdmi and plug it back in. The other day it happened again I turned my PC off took the hdmi out started it up and I had a red line around 3in thick going down the side of my monitor, got the the msi screen and it was was littered with red and green lines. Got to my desktop and it was normal but next day it did it again and it didn't get a signal anymore, I unplugged it all plugged it back in, tried different monitors, tried different hdmis and nothing worked. When I start up my PC it says no signal and the mother board says "b2" where my temp ussally is. I have no idea what to do if anyone could help it would be great.
