I have a HP p7-1062sc, (http://h20564.www2.hp.com/hpsc/doc/public/display?docId=emr_na-c03069326) and wanted a new GPU.
So I have bought a corsair cx600 powersupply, and a gtx 960 gpu.

After having plugged in the new hardware I got the problem that the pc would only get to the blue HP screen, and then freeze with error-sounds coming from motherboard (wont enter bios either).
Tried putting the dvi directly in mobo, same problem.

I disconnected the new gpu, and plugged dvi directly in mobo, it boots up fine. Plugged in old GPU, dvi in that, boot up fine.

I then googled a lot, and read a lot of ppl suggesting something about disabling "secured ports" in bios, so I did that. (my system had win7 when I got it, now it have win10)
Now I can boot it up without error from mobo, but when I put dvi in gpu it just gives black-screen (same result from hdmi).
It boot up fine when I just plug it in mobo, so I seem to have made some sort of progress, although it is merely theoretical..

I cant install drivers, since the NVidia software requires that the correct hardware is attached, and apparently it cant discover it. There is no old drivers, I have just done a clean install and I tried that ddu-software, so I don't think that's it.

I'm a bit of a noob, and I'm running out of things to try. Can someone pls tell me what is wrong?

edit. I tried connecting my old gpu with the port security disabled, and it also gave black screen so it wasn't progress after all I think.
When turning on computer with new gpu in slot but not connected to power, it still lights up. My old GPU didn't have a powerplug, can this have something to do with it? Do I have to tell my mobo to stop trying to power my gpu, or something like that?
Sry if I'm asking stupid questions.
