Help with Realtek RTL8029 Network adapter

My Realtek RTL8029 Network adapter has crashed when powering the PC on, so
firewall, antivirus, etc failed also.
I reboted PC into safe mode and removed network adapter, then rebooted
again, but windows detected adapter as "PCI early non-VGA device".
I was not able reinstall drivers, after specifying path to folder with
drivers in Driver Wizard, each time theWizard show it can no find drivers. I
removed Registry key where was stored pathes to drivers location (few
pathes), then, on reboot, the adapter was recognoized correctly, and I was
able to reinstall drivers sucessfully.
But after rebooting, windows show message that the Network Adapter is not
functioning properly, and it highlighted in yellow in Device Manager.
I repeated adapter uninstall/re-install process, but this not help, still
show "Network Adapter is not functioning properly".
Can anyone help please?
