[SOLVED] I Bought a new gpu and after installing it its showing blackscreen

[Danixhd10]

My config:
Intel Xeon X5670
12Gb 1600mhz
SABERTOOTH X58
RTX2060 (worked) My new 5500xt
Koling Kl-600 Psu

I tried bios update and not worked i installed it in to my friend's pc and its worked in his pc. When i start my pc its starts to boot up but when it needs to show the windows logo its shows blackscreen and nothing happens.

Does it still start with the RTX2060?
If so, use DDU to uninstall all leftover display remnants, reset the CMOS, and shutdown then install the new card. It would be easier if you download the new 5500XT drivers and have them on either your OS drive or a USB stick first though.
