R7950 Display problem (Needs to restart to be detected)

LionheartRichard · Apr 4, 2014

Intel Core i5-4670 @ 3.4GHz
R7950 (http://www.newegg.com/Product/Product.aspx?Item=N82E16814127737)
8GB Corsair Vengeance RAM
800 Watt Power Supply
Asrock B85M-ITX Intel B85 Sata 6 USB 3.0 MITX LGA 1150

My computer has had weird problems ever since I bought my graphics card months ago. When I fist turn it on, the card isn't detected. Instead it goes straight to the integrated card. When it is running the integrated cad, it runs just fine, except for the fact that it doesn't detect my graphics card (the fan still runs though).

After my computer has been running for awhile (the amount of time seems random, sometimes it needs a few minutes, sometimes a few hours.) I restart my computer and change the HDMI cable from the motherboard to the graphics card because the card is now detected. If I keep my computer running 24/7, I don't have to repeat this, but if I so much as sleep my computer for too long, it won't wake up. When I press a button, the fan starts up again, but there is no display and I have to hard restart my computer, which then boots to the integrated card.

Another weird problem is that sometimes when I turn off my TV and turn it back on again, the screen is cut off. I have to wither change the resolution and change it back, restart my TV, or unplug and replug the HDMI cord. Any of these will fix the screen. Sometimes the audio also randomly stops when changing resolution for games and I have to do any of these steps to fix it.

Drivers are up to date by the way. After months of this, it is getting very annoying. Is there any way to get my computer to instantly detect my card without it having to "warm up"?

do you have more than one cord hooked up to the card when you are starting it

LionheartRichard · Apr 4, 2014

You mean the power cords? Yes, I have both slots plugged in.

coolcole01 · Apr 4, 2014

no i mean one hdmi or dvi cords

LionheartRichard · Apr 4, 2014

No, I only have the HDMI plugged in.

coolcole01 · Apr 4, 2014

i have similar issue where if i turn on my computer before my tv is on it wont send a signal to the tv and i have to reboot it to get the signal to start
But anyway does this hook straight to the tv or does it go through a receiver. Also do you have more than one hdmi on hand?

LionheartRichard · Apr 4, 2014

It goes straight to the TV, and its my only one. I also don't have a monitor to test it on.

coolcole01 · Apr 4, 2014

its cool anyway its weird that the integrated graphics are not automatically disabled when it is started have you ever went in to the bios and just deactivated the integrated graphics to stop it from trying to use it.

LionheartRichard · Apr 4, 2014

I've done it from control panel when it was the one selected, but not from BIOS.

LionheartRichard · Apr 4, 2014

Does anyone else have any ideas? I don't think a graphics card needs to "warm up" to get going.

Jaxem · Apr 4, 2014

No reason it should need a "warm up" period, if you've got whatever menu/bios settings you have to default to PCIE graphics instead of integrated and it's still doing this, it's probably time to start eliminating parts and figure out what to RMA. If you have or can get ahold of for a day, try sticking some other GPU in and see what happens

LionheartRichard · Apr 4, 2014

I'll do what I can to find another GPU to borrow, but in the meantime, is there a chance that it is the motherboard's fault? I have a warranty on mu GPU as well as the rest of the computer, but taking advantage of the GPU warranty is going to be a bit harder as I can't find any proof of purchase anywhere.

Jaxem · Apr 4, 2014

There's always a chance it's the mobo, bad pcie slots do happen. Many times you don't need the UPC to RMA, as you're required to send the card in first...kind of proving you bought it.

LionheartRichard · Apr 4, 2014

Good to know. So if I try a different card and it works perfectly, its the card's fault, but if I have the same problem with a different card, its the motherboard? It looks like this is the question that would solve all my problems.

Jaxem · Apr 4, 2014

LionheartRichard :

Basically...yes. doing a quick swap with a friend or old/cheap card should tell you exactly where the problem is, which would answer your question. It's just difficult because most people don't just have extra cards laying around.

coolcole01 · Apr 4, 2014

depending on what country you live in i would take advantage of best buys very nice return policy go buy a card from them and take it home and test it if it works fine take it back before two weeks for a full refund

Jaxem · Apr 5, 2014

coolcole01 :

Not a real honest way to go about this...

coolcole01 · Apr 5, 2014

I dont see how its dishonest you are not hurting it you are returning it intact

Jaxem · Apr 5, 2014

coolcole01 :

That's like buying a big screen TV to watch the Superbowl/World Cup, then returning it. It's not exactly honest if you have no intention to keep it. You're hurting the business.

coolcole01 · Apr 5, 2014

Hey when your poor you got to do what you got to do. Its nice if you know someone who will let you but when you have no ther choice. Or just enjoy a busted machine.

Jaxem · Apr 5, 2014

coolcole01 :

I'm sorry, but being poor isn't an excuse for anything, it just means you have to be more patient and save longer. It doesn't give you a free pass to gray area shortcuts. It's obviously not illegal or anything, but i feel sad for anyone that can feel good about taking advantage of people that way.

coolcole01 · Apr 5, 2014

Well the next time you buy a 250 dollar card from a company and they gouge you and you have to pay 400 go ahead and feel bad for them. Have a good day.

Jaxem · Apr 5, 2014

coolcole01 :

You as well (have a good day).
