Black screen, possibly faulty GPU?

post #1 of 9
Thread Starter 
I had some problems crossfiring earlier, and after I thought I had fixed the PSU problem, it up and died again.

It's now been replaced with an EVGA SuperNOVA 1200 P2 and everything's all in working order and lovely once more!


However when I went to crossfire again, my screen went black, and my PC would not respond to anything but holding power for 5 seconds (even reset wouldn't work)
Took my build apart, rebuilt it and rechecked it to make sure... Same problem, after roughly 2 minutes my screen goes black and everything is dead. (including the LEDs on the second GPU but not the first)

So I took my GPUs out, rewired everything again to make sure, and put it in only one GPU (Sapphire R9 280x Vapor-x) and booted back up, the exact same issue...
So I took out my GPU again, and put in my original GPU, booted up, and here I am, typing my story to you guys. Not a problem to be found.


I also have reseated my CPU, fiddled about with my RAM sticks one at a time, and tried my old 6970 card to see if it was just my one card or my PC was doing this in general.
^ This did nothing, only that one GPU in any configuration (top card, bottom card, only card) causes this.



So I know what's wrong, it's the new GPU, but now the question is can I fix this? Possibly with a bios update (these cards do not have the same bios by the way) or drivers maybe?
Or is this something I should get replaced and send it back?

Send it back, get another one. You can still return it ya? I wouldn't go thru an rma unless I had to.

I was hoping there'd be a quick fix, because I'm impatient with shipping.

Oh well, off it goes!

There are some things you can do but usually a blackscreen in basic tasks equates to a defect. A game load is a basic task but it's a focused task which actually removes a lot of other variables. If you blackscreened only in flash, browser or youtube related stuff thats a setting that can be fixed. Blackscreen going into a game is not good.

It's done this while on CCC, while on Chrome, and the one time it stayed active long enough to get Steam to load something, on Counter-strike: GO as well.

Hmm, ok. Here, you can try following my guide which will cut down on powerstate switching. A lost of the user configurational blackscreens are from powerstate changes, one state sets voltage low and is not able to respond quick enough as a higher state is called. Pay attention on the section related to controlling rogue hw accelerated apps and how to find them and disable them.

Voltages still confuse the hell out of me, but since I wouldn't be able to return this anyways (no shipping on weekends) I have plenty of time to work my way through all that.

Thank you! I just hope I can keep my screens alive long enough to get through some of this.

Try switching to the hdmi port if possible. It's more blackscreen resistant.

Actually this has been happening on both my main display on displayport, and my second display on HDMI, individually because I thought it had a chance of being the monitor since it was new.
Longest I've gotten it to stay up so far is about 3 minutes, cant keep it up long enough to do anything, decided to RMA the card.
