ok guys, I upgraded my 5970 ATI and installed new 7970 MSI Lightning. I decided to use DirectX11 with my new card (before I was using directX9). After 15 min of playing my GPU usage goes to 98% and cause a black screen and crash. (temperature is around 60) If I use directX9, I have around 60% GPU usage and everything works fine but I have less FPS :( 
What can be the problems here ? My friend has ATI card also, but he has no problem at all.
I have new 12.8 drivers installed. I tried Guild Wars 2 and I didn't have any problems.
Is my new graphic card rly that bad or its problem related to World of Warcraf ?! please help me

It sounds like a problem with the Application (WoW). If your card works fine with other games and then messes up when you run DX11 on a DX9 game then maybe it's a glitchy mod for the game. I don't know much about WoW so I can't help you with the texture packs or mods or w/e. But this sounds like software issues...

Just a shot update guys. I tried to test out 3Dmark demo and here it is:
Please some advice, I had rly low FPS with my CPU test ? Is that normal ?
I am thinking that my problem is actually not GPU related ?

Didn't realize you only had an i7-920 for your CPU... it's quite possible you're seeing a CPU bottleneck in WoW.

Do you have a nice enough motherboard and CPU cooler that you can overclock the CPU a bit and see if it helps? Those 3dmark framerates look like what I'd expect from your system.
September 2, 2012 11:55:37 AM

really strange. Atm I am running WoW mid graphic settings with Dx11 and I didn't have any freeze so far.

little off topic:
I was thinking to buy ASRock z68 extreme7 gen3 and I7 3770K. (copycat heh). Since I didn't plan to change my case, I was wondering if this motherboard can fit into COOLERMASTER CM 690 II?
September 2, 2012 12:05:43 PM

It's a nice board but would be very overpriced for your setup.

The main advantage of the board (and why I got it) is that it does PCI-e 2.0 x16/x16 (that's the main difference over their cheaper z68 extreme3 which will only do PCI-e 2.0 x8/x8).

However, since you are thinking of getting an Ivy bridge CPU that will do PCI-e 3.0, I'd probably say that you should save some money and get a Z77 board... if you like ASRock then their z77 extreme4 will be functionally just as good for you but it's a lot cheaper. Don't know that case well personally but as long as it can fit a standard ATX motherboard then any of those should fit.

Your case will work. Get that Z77 Extreme4, great board, use the money you save for a nice CPU cooler.
September 2, 2012 1:50:29 PM

ya thanks guys. Tho I have plans to buy another 7970 Lightning and go with crossfire :) . As it is now, I ll change CPU+motherboard and get new SSD. Reinstall my Win7 and check if freezing will happen again.
September 2, 2012 4:44:03 PM

Just remember that PCI-e 3.0 x8/x8 that you will get on a moderately priced z77 board like the ASRock z77 extreme4 is just as good as the PCI-e 2.0 x16/x16 you will get on a much more expensive z68 board like the z68 extreme7
September 2, 2012 6:41:26 PM

so basically only major difference between those two motherboards is 3 way crossfire vs 2 way crossfire ? Price difference in my country is 100 Eur.
Also, what do you guys think about CPU ? I was planing to get 3770K or 2600K (price difference is like 30 Eur)
Cooling system will be Noctua NH-D14. (I do plan to overclock)
After I get all those new things I hope freezing thing will not happen again.

why is 98% usage bad? would you rather have 10% usage and 5fps? makes no sense...

you are right. At the first moment I was thinking is GPU problem, but since my fan speed and temperature are ok, I think problem is something else.

I wouldn't use a beast of a card like that with a ASRock z77 extreme4 lol but to each their own

Can you explain why? and what do you suggest ?

The only negative I have for this motherboard is that it slips outside of typical ATX specifications. It’s 3cm thinner than a standard ATX motherboard and as a result may lack secure mounting on the far side since this isn’t a common size, which also means you should be very careful when plugging in the 24-pin ATX motherboard power – as the motherboard may flex.Asrock makes solid mobos they get great reviews but the cheaper ones are made funky yet review sites give them big respect lol sorry i find it crazy so i laugh not to lose my mind over sites giving bad advice. I would suggest one of these motherboards mobo:ASUS P8Z77-V LGA 1155 Intel Z77 HDMI SATA 6Gb/s USB 3.0 ATX Intel Motherboard

mobo:GIGABYTE GA-Z77X-UD5H LGA 1155 Intel Z77 HDMI SATA 6Gb/s USB 3.0 ATX Intel Motherboard

This one by Asrock is basically the same but they made it solid is why it is getting my recommendation not because TH recommended it as this site sometimes gives not long term smart recommendations imho. mobo:ASRock Z77 Extreme6 LGA 1155 Intel Z77 HDMI SATA 6Gb/s USB 3.0 ATX Intel Motherboard

short update guys. My PC freezes again,but this time I got blue screen:

please help :( 
September 3, 2012 11:49:16 PM

Are you overclocking?
0x101 errors are quite common when overclocking with not enough Vcore.
September 4, 2012 7:03:27 AM

nah I didn't overclock. I did BIOS update and chipset upadate, but it happened again.

Is it possilbile that my power suply is too low? I have Chieftec 850W ?

September 4, 2012 11:51:41 PM

short update
I updated my Win7 and guess what, my problem is gone (hope that I will not curse it now lol). Thanks all for help anyway!
September 5, 2012 11:48:37 AM

Well I was going to reply to you this
"Before going the full reinstall routine of win 7, go to wow launcher, click Options, go game preferences, click restore defaults, that should restore wow settings to defaults, enabling it to use all the CPU cores at same time. Also google how to delete wow config files, just to be sure if problem continues.."
And also
"Reset your Cataclysm, err I mean Catalyst control center 3D settings to defaults, and check that all settings are on "Use application settings" and so"

But what I read is, you did bios update, and that quite recuires whole windows 7 reinstall so that Windows detects the stuff propely, if new features are enabled or so. I didnt know this on my old motherboard and that might have been major issue with the ministutter issue with it, but it was rather old so I went with the whole system upgrade option. Meh.

Good that you got the stuff fixed and happy raiding/pvp.

Also blue screen might be the cause of faulty cpu/memory/graphic card memory.. but also can be caused by wrong "recommended updates" that Windows 7 promotes you to get. Just download all the "necessary updates" that it tells you to get until the point it doesnt update stuff anymore. Then you might want to see for the intel/chipset updates what ever you can get. Intel has chipset drivers that you can download from their official website, its auto update. Oh and remember to update directx drivers while you are at it. But I guess you know this basic stuff already. Have fun with working computer.
