[SOLVED] display won't turn on and no beep after installing new graphics card

Jan 8, 2021
Hello guys so a month ago I got a bugdet PC and it came with a AMD Vega 8 graphics card. I was not relly happy with it so my friend gifted me a HIS R9 380 IceQ X2 OC 4 GB. I have not done this in a long time so just rushed plugged in the new graphics card, my pc turned on I was about to search for a driver to install but my computer was in the way kinda so I kinda just gently pushed it back a little bit not hard or anything and I just heard like eletricty sound because I guess I pushed against my power supply cable the computer kinda just lost power and automatically came back on itwasnot pushed anymore and since then I can not get a signal on my monitor. The fans are on,the graphics card fans are on , cd rom comes in and out , ive tried three different monitors , all different types of cabels . I have tried to remove the new graphics card and trying to run the original one I had and it dose not work also I get no beep on start up , tried removed the RAMs and had a beep when they were out but when I put them back in same thing again.. So yeah Im really lost on what do if anyone has had this problem before and know a fix that would be great. So yeahI think everything was okay until I pushed against my power supply cable it made the eletricty noise and since then no displey on all GPUs old and new same problem....
