Most drivers should be provided by Dell so Dell would be your main source for the drivers and the ONLY source for BIOS updates.
If a driver isn't provided by Dell, lookup the official support site of the company to find the right drivers.
For example GPU, CPU and input devices (mouse/keyboard), for these drivers you could check Nvidia, Intel, the support page of the company. For the GPU Dell sometimes does provide drivers too, but with desktops you could also get them from Nvidia :)
