T5500 problem with 1650 graphic card

Recently got myself a refurbished T5500 with 2x E5645 & 48GB of RAM. Also, I've updated BIOS to A18 (latest one). It came with some ATi 7790 Radeon HD card, which doesn't suit me. More info about the computer can be found here: https://setiathome.berkeley.edu/show_host_detail.php?hostid=8865481

Also, on Black friday I've bought a 1650 card, which fits perfectly. But the graphic card does not show video, even though the system seems to be booting.

Did anyone had a problem installing 1650 on T5500?
