Hello, I'm new here and heard this was the place to go for help. I've got an HP 8770w that came with the Firepro M4000 originally. I bought a Nvidia K4100M and the corresponding heat sink as a replacement. I've installed it but get a black screen at startup. It almost seems like it tries to start and then the light on my mouse goes out and it tries again. I was going to delete the old drivers and install the new ones after it started up. Should I install drivers first or am I missing something else? I can easily do the disassembly/reassembly stuff but my knowledge is limited when it comes to software. Any help you guys can give me is greatly appreciated!
