How do I change my graphics cards bios?

[spixelspixel]

I want to flash my gtx 570 bios as its unstable at its stock clocks (factory oc too high on the memory).

Anyone want to give me a quick noob proof guide? Would be much appreciated.

DOS is the safest way.

So confusing, any way to sum it all up in a few sentences? Am I meant to edit my current bios or use a completely different one?

Nvidia Bios Editor assuming you have a custom bios ready to flash.
