I'm more familiar with 1850s and 2850s which have all had PCI slots, but you didn't mention having removed the DRAC card. That turned out to be the main stumbling block for me, and I've been able to upgrade two 1950s with PCIe cards relatively smoothly following the same sequence: remove the DRAC and power up, disable and uninstall device drivers for any graphics adaptors or displays that appear in the Device Manager, then shut down and disconnect your monitor from the integrated VGA. Install your new graphics card and boot up to install your drivers. This first boot with the new card and no drivers is the worst bit, and as garbled as the screen appears, or if it goes to sleep, don't be tempted to restart - it has taken up to 30 minutes for me. Once you've installed your drivers you should be sweet. Never connect anything to the built in graphics again, trust me! Apologies if the 1800 doesn't have a DRAC, I've never opened one.
