*Edit:

I fixed it. The card diddnt like some windows aero features and for some reason caused it to crash.

I turned these features off in safe mode and it now works perfectly. I've got it in game running smooth as butter.*


So, This is kind of a long story.

TLDR: GPU works in my main PC but not in my secondary. Specs:

Non working with GPU:
I7 6700kCPU
Asus H110i Mini ITX MOBO
16GB 2333mhz RAM
(New line)CX650M PSU

Working with GPU:
R7 2700X CPU
X470 Prime -F MOBO
16GB 3333Mhz RAM
EVGA G1000 PSU

So now for the longer version.

I bought an RX 480 n eBay for £30 "non working, black screen when in windows". Every other time I've seen this problem it's either A: Dead bios. B: dying or crappy PSU. So I bought it and threw it in my main PC, low and behold it works.

The reason I bought this is for my dedicated VR PC as it's been built totally on the cheap (£120 with the GPU).

Once I got the card, I took out my 1080Ti, Nuked the drivers, put the 480 in and got drivers installed no fuss, and boom GPU works. Played Overwatch at 1440p just fine, so cleaner my driver's, put my main PC back together and went to put it in the mini PC, and as soon as it got into windows after about 5 seconds it black screened.

So with that I thought that maybe my PSU was dead, it worked with my R9 280, but that's years old, I was dealing with an old line CX750 Here so, I got a new line PSU that's brand new from my girlfriend (it was used for about 2 weeks before being replaced with a EVGA P1000 so it's fine)

I've tried a lot here, I've got drivers installed by having the CPU as the output monitor and it just crashes. I'm at the point here where I genuinely do not know if it's windows fuckery, or there is something wrong.

Any ideas or next steps for me to go with here??

Thanks!

Since you already have another PSU to try, it won't hurt to swap PSUs to make sure that's not the problem.

In the secondary PC, do you have everything updated? BIOS/ chipset/ windows, etc...?

I've tried it on 3 different power supplies. I'll have to double check the bios and chipset as I'm not sure.

Good direction to go though, thanks!

That's... unexpected. I really thought that PSU was partly the problem.

The BIOS shouldn't mess with windows. I am not sure how you should proceed, maybe someone else can contribute here.

yeah my first thing was the PSU which is why I bought it. and again, it works in other systems just not this one.

So I reinstalled windows, and now I can get into windows, but the card artifacts like crazy and windows has to keep refreshing explorer to come back to life.

Tried it in my other PC again, works fine without drivers, and with drivers.

Also might be worth noting in safe mode this is not an issue at all
