Need some help

Hi , i recently installed Mac OS Mojave on my old windows pc , which is a HP laptop with core i5 and has a Nivedita 740 graphics card , i installed the dmg file from the hackintosh shop and it did work , but once in there , the graphics card did not show up and i was not able to connect it to an external Monitor using HDMI , even my mouse and keyboard would not work properly and the audio also did not work , i tried many YouTube videos and all of them used clover config , and I mounted the EFI , but in the clover fie i only found a singe file which was not the one that was supposed to be there , i also was not able to connect to Wi-Fi and had to use an Ethernet cable and nor did Siri work due to “ no microphone detected error “ i do not know how to solve this and also tried to update to Catalina but the installer said no partition firmware and i was no able to update on my external Harddisk { primary disk with the mac Mojave installed } , the mouse kept on slipping and opening different files , anyone know how to make this work , i do know have clover installed on either windows or mac. Please i need someone’s help. …………
