7950 Boost Problem

[Estbarul]

Hello, I'm new to this forum tho I like to read it from time to time, mainly about Vega and Polaris, since forums like Toms Hardware are full of people who talks much but doesn't know much, my first post!

Anyway, I bought some time ago a second hand GPU, it has worked out fine for about 6 months but a couple of months ago it started working weirdly.

When I boot, the boot even before the BIOS startup is really slow, like a couple of minutes slow, compared to 10 s in which it boots without the GPU connected and getting the signal from the mobo to the display.

Sometimes it boots fine but just before the Win 10 login screen it hangs. The weirdest thing is I can play any game fine (outside of Dota 2, that thing crashes with the iGPU or the dGPU, some issue with my CPU probably), but I ran Wolfstein, Alien, Doom, Witcher 3, all fine in my GPU once it booted, the problem is mainly the boot time.

Any help would be really appreciated, I got the 7950 out to test it on a friends machine for now, if it's an issue with mine.

My specs are:

i7 5775C
8 GB RAM
SANDISK 480 GB SSD
GA z97n wifi mobo
Dual X 7950 Boost 3 GB

Welcome! Does it do the slow boot issue with the integrated graphics? If not, that would point to be card related. Also, it would be good to know your PSU, just to make sure that is not the issue. Finally, have you tried a GPU stress test on it? If it fails or artifacts, then you know the card is going bad.

Hey! Thanks Shmee, I can boot just fine without the GPU connected, but the weirdest of all is, I tried it on a friend's PC and it worked fine! Booted and played just fine Dota 2 and Witcher 3. The only thing different from them is that I use HDMI on my PC buy on my friend's is DVI. Even tho, I don't think that would be the difference.

Is there something wrong with my mobo instead? or CPU even? it's so weird. I got a RX 480 4 GB now but this seems like it's working, just not on my system. My PSU is a Silverstone SFF 500 W so it's a pretty good one! I haven't tried stress test, not recently, only like 6 months ago but I did have weird issues back then. Results were fine.
