So the thing is I just bought my first good gpu, MSI ARMOR RX 570 8GB OC edition. My old one was Nvidia GT 710 2GB DDR3. So i took out the old one and kept it ready to buy the new gpu. In the shop I realised that my psu wasn't powerful enough and it also didnt have a 8-pin connector, which the RX 570 needed. I didn't have the money for the psu so I just bought the gpu and decided to buy the psu later. After returning home I put back the old gpu. But somehow my monitor just won't turn on. It says "No connection from hdmi." I am worried, did something happen to my old gpu or is it some other issue? I watched many YouTube videos and did what they told but nothing helped. So I decided to just remove the old psu and the gpu and install the new gpu and keep it ready. while installing the new gpu, at first the brackets didn't fit properly. After applying a bit of force, it made a somewhat loud noise and got in properly. Can my new gpu be damaged from that? I am really worried.
