So I just took out my GTX 970 out of my pc, making sure to turn it off and unplug everything beforehand, and now that I plug everything back in and boot it up using motherboard HDMI, it just beeps 3 times and doesn’t show up on my display. My specs are:
MSI b350m gaming pro
Corsair vengeance 1x8gb
R5 1500x

Keep in mind everything has been working fine until I took out my gpu to sell it.

So this is expected to happen and I’m worrying for nothing right? I’m getting a 1070 in a few days so as soon as I get that I should be fine? Thanks for the quick reply
