Graphical glitch AMD radeon 6490 Macbook pro 15" 2.0 i7 quadcore

I have graphical glitch that seems to happen every once in a while. its like the screen gets a line draw in the middle of it when i move the cursor up or down or when i make the dock reappear or when i move the pages on safari or any other app.

I'm still reluctant to give up on that bricked machine... Since it is able to display part of the boot up messages of the arch install cd and the previously working installation showed everything until loading of the virtual console (at least that's what I believe it did when the screen went black), it looks to me that the problem lies in initializing a different graphical output. That would also explain why I was able to initialize X only with the fbdev driver... and the screen didn't flicker during boot-up when I did radeon.modeset=0 so I assume it stayed on framebuffer mode all along.
Does anyone know of a boot medium that boots into framebuffer video mode even though a GPU is present? All I'd need is a bash or similar shell. I can load into the UEFI shell with arch install CD, but I'm not familiar with that shell and it follows a different syntax than I am used to, as it is designed for an entirely different purpose. If anyone knows a boot medium that does not try to pipe the graphical output through the gpu (or the integrated i915 graphics). Must be something like this around?

IMac 27" 2011 with Dead Graphic Card AMD Radeon HD 6970M

Hello
I'm from Thailand and my iMac 27" mid-2011 model is malfunctioning. I have windows 7 installed and I can use it only on safemode or when I disable the graphic card AMD Radeon HD 6970M. Updating the driver won't help at all.
I talked to the local iservice and he says it will cost me $570 just to replace this card. I find it very expensive.
Now I have learned that there is this replacement program http://support.apple.com/kb/TS5167 for the graphic card issue. I'd like to know if I am part of this. I'm not sure if I'm under any service coverage since it's been after many years of purchase.

You should be covered - usually replacement programs last for 3 years from the latest date of consumer purchase (when apple discontinues the model). This is typical, but by no means concrete as I have nothing to do with Apple or its replacement policies. Your model also meets those specifications. Since the replacement program is stated as wordwide, it should also be applicable in your country.

Is there an Update Driver for my Graphics card, AMD Radeon HD 6970M 2048 MB , in a 27inch mid 2011 iMac? thank you!

THank you very much, I I have a ton of Adobe programs on my mac and i think a Cuda driver update was installed with it, it just popped up the other day in my system settings and is asking to upgrade my graphics card, but i don't have the same card as this update... so i thought i would double check! thank you again.

Hi @Fodi
Welcome to the HP Support Forums!
Ok, I understand that you are trying to install drivers for your graphics adapter and the one built in to your cpu.
In reality you do not need to install the separate drivers. It is covered by the main driver for your graphics adapter when there is both an integrated and discrete gpu.
As to the Error 43 - please see this page: Expand Code 43: Windows has stopped this device because it has reported problems
Since you have tried several times you may need to remove both drivers and restart the system and let the os find the built-in graphics, before installing the driver for the AMD device.
All the various drivers for this notebook that have been HP customized can be found here:

Screen has a 'solarized' look on start up, which disappears after about 30 mins, suggesting a 'warm up' issue?
Am aware of Nvidia issues with Macbook pro but this machine has the following graphics/display on logic board.
Does anyone have a view on this matter and a way of resolving it? Still under extended warranty.

You said the magic words: Still under extended warranty. Take it in for evaluation and repair. That is not a normal situation. The display should not have to 'warm up'.

AMD Drivers in macbook pro?

Hello to all,
I have macbook pro (Late 2011) AMD 6770m graphics. I installed Windows 8 via BootCamp. My question is if I install Catalyst Software (Latest 13.1) from AMD site then: Will it cause the crashing of Windows 8?.I am asking this because last time I installed Catalyst, Widows 8 crashed saying "BAD_POOL_HEADER".
And my other question is:
I am really curious about the graphics switching between Intel HD 3000 and AMD 6770m..Will I be able to switch? If yes then how?
Thanks for the Cooperation.

Windows 8 is not yet support under Boot Camp on Mountain Lion. You chose to install it nonetheless. There will be problems, as you're seeing. If I were you, I would wait until Apple announces support for Win8 under Boot Camp and just run it as a virtual machine if you must run it.

Is there a way of improving my graphics on my early 2011 macbook pro 13"?

Does anyone know a way of improving the graphics capability for OpenGL with the Intel 3000 chips in the early 2011 MBP 13"? I bought it not realising the graphics chips had been downgraded and now as a result struggle to do any CGI work that I rely on my computer to do.

I'm more inclined to go with Ogelthorpe's advice (if I had the cash).
I agree with Ogelthorpe as well, the 15" and the 17" MacBook Pro also have dedicated graphics cards which give more performance than the Intel HD 3000 only graphics, which is really of MacBook type performance for consumer user. (playback of video and that's about it)
Still wondering why Apple went backwards for graphics in the 13", I completely missed the change.
I'm peeved at Apple for the fact that they didn't make a clear distinction of the disadvantages of the 13" with no dedicated graphics card then lumped it in with the 15" and 17" which do.
To Apple it's a matter of performance for price, the 13" scores 11 on Cinebench, the 15/17" score 30 and 45, so the 13" doesn't even come close. But it comes in the same silver case, the same "MacBook Pro" name, when in fact it's not so.
Apple knows people would be attracted to the performance of the MacBook Pro name in a small size factor, the price is also attractive to the younger crowd, the younger crowd are also interested in running 3D games, which need a more powerful video card.
Your not the first who's complained and feels burned, you trusted Apple was selling you a powerful MacBook Pro machine and you've got a consumer machine instead.
The 13" Mac laptop should have gotten it's own category, called it a MacBook instead and it should have come with white or black case. But that would have angered Intel most likely, who are trying to push integrated graphics on their CPU's so they own the whole show eventually.
It's going to take a long time before CPU integrated graphics is ever going to beat dedicated GPU graphics, because 3D game detail is always going to go up until it finally reaches 3D raytracing at 200 fps.
What Apple is doing is trying to get folks hooked on lessor quality/detail games, the ones you see on iPads and iPhones, and away from wanting rich detail which needs a powerful dedicated video card.
So Apple lumps the 13" MacBook in with the MacBook Pro line, try to force the issue, next they will try it with the 15", integrated graphics on the low end model. Then again only dedicated graphics on the 17" model and so forth. Eventually developers won't make as many 3D games for Mac's because most people buy laptops, cuts into their potential sales.
If you really want to run 3D games, you have to go with a Windows 7 desktop where the video card can be swtiched out.

Jerky, laggy graphics on windows 7 on macbook pro but graphics are fine on OS X

I installed windows 7 and all the apple support files for windows using bootcamp on my brand new macbook pro 15inch.
I get very noticeable laggy, jerky graphics on videos that i play with VLC or windows media player in Windows 7.
If there is motion in the video you can really see it is not smooth.
and the quality of the display of youtube videos is much better on OS X than on windows but not jerky.
BUT if i play exactly the same files on OS X mountain lion they play perfectly,please help.
The apple support files for windows are up to date as well - I checked.
My Spec is Windows 7,
And the most recent OS X Mountain Lion.
2.6Ghz quad core Intel i7
16 GB RAM.
and the rest of the normal spec for a brand new macbook pro.
Any help would be massively appreciated.

Uninstall the graphic drivers you have, then download and install these.

I grasp that you are having a difficulty installing an AMD driver as you have switchable graphics.
You provided your model but when I checked the specification page it came with Free Dos. What Operating System are your running?
Here are two documents to assist you with this difficulty.

I am unsure of where you obtained the driver update, but you should only use the recommended ones from HP .
Here is a link to the HP Pavilion g6-2332se Notebook PC Drivers. You will need to select the correct Operating System and follow the prompts to display all the recommended drivers for you.
You may also consider contacting HP support for further assistance.

Glitch at shutdown? Macbook pro retina display late 2013 model

Hi,
I have the late 2013 model of the macbook pro retina display. Since the past few weeks, I've been noticing a glitch at shutdown. This started to happen after my macbook asked me for my keychain password. How can I fix this glitch?
Before the whole keychain password: My mac would take a good 30 seconds to turn off properly. There would be a grey screen for a good 30 minutes.
After the whole keychain password: My mac just shuts off in a second literally but the grey screen doesnt appear. These a glitch. You can see the dock trying to go down at shutdown but because of the glitch it just stays there.
How can I fix this? Should I get it checked out?

Please make a Genius Appointment and take it in for service. Ask for the glitch specialist.

Short answer--buy the Apple drive if it is an exact match and you are not buying from Apple.
I had a Toshiba in my last MacBook Pro and was not impressed compared to other SSD drives (above) I've used. It was the slowest SSD I've owned--but still plenty fast. However, if you are buying it off eBay, it is not a bad idea to get an exact duplicate of what you have--saves money and the RAID 0 configuration would nearly double the performance--you would not be unhappy.
I don;t like Crucial, but I have no experience with them, other than reviews, and Newegg reviews are not that great, from what I recall. Check for yourself though.
Finally you can RAID 0 two different drives. I would lean away from that, but it can be done if you want to save a few bones. Performance would be at the rate of the slower drive. Why, if you can get two identical drives?

Graphics card/logic board issues: Macbook Pro Freezing during Apple Hardware Test!

I have a macbook pro that was working fine then the screen started acting funny. It would sometimes "tile" up where you would see the same issue repeated over and over on the screen and then computer would freeze. Sometimes the screen would start to have a strobing look and then freeze. I thought the computer was crashing but once the screen froze but the processor was still running. I knew the computer was still processing because I was streaming a video online and the audio from the video continued to download and play event though the screen was frozen.
I went to the apple store and they said they think it sounds like failure of the hardrive, graphics card, display, logic board. A new hard drive was just put in the computer about 4-6 weeks ago, and if it is the other issues could be $500-$800+ to repair. I tried to use the Apple Hardware test (non-extended test) but it keeps freezes at 2 min 32 secs every time when it starts "testing the main logic board"....
Has anyone seen anything like this and have another way to test what the problem could be? Thanks!

I know you're in denial, but it really does sound like the motherboard or graphics board which is integrated with the motherboard. Yes, fixing these things will cost almost as much as a new MacBook Pro. Get a new one, take the HDD out of your old one, and start over again.

Graphics Error AMD Radeon HD 7640G/7670M Dual GPU

HI,
I am facing a problem with my HP Pavilion g6-2301ax Notebook PC with AMD Radeon HD 7640G/7670M Dual GPU (2 GB DDR3 dedicated) with Windows 8 64-bit. I haven't made any changes to the hardware/software nor have I connected any new hardwares.
I cannot watch Videos no matter what program I use, be it VLC, Media Player, etc. The programs simply crashes. It takes quite a considerable time to boot and Restart/Shut-Down, than before. Here's a screenshot of the error message...
Also, the AMD Catalyst Control Centre keeps crashing...
Before, the Graphics Control Interface was totally different. The so called "Hydra Grid" wasn't there. The Control Menu had more options and the ability to customise. Since, it is a Dual GPU, there was an option whether to choose both or just one. This problem started like 2-3 days back.
I am really really frustrated. Because of this, my work is getting hampered a lot. Also, it doesn't read an external Hard Drive which has USB 3.0, even though the "safely remove icon" is shown at the task bar. And now, because of this I can't even Back-up my files on to the external hard drive in order to Recover or Restore it to Factory Settings.
Somebody help me.
Warm Regards,
Zamyang.

I understand that you are unable to play videos regardless of what player you try. You have not made any physical changes to your notebook or added any external hardware.
When you connected your External drive you get the safely remove icon but does not install the drive.
If you look in device manager does the external drive have any bangs or error on it. Have you checked the manufacturers site for a driver for it?
If you check disk management does it have a drive letter assigned to it?
Here is a link to
Testing for Hardware Failures (Windows 8) that may to determine the cause.
You state this happened only 2 -3 days ago and you cannot do a restore as the external is not being seen correctly but you should be able to do a recovery back to factory.
Do you know in updates were automatically installed?
Here is a link to Performing an HP system recovery (Windows 8) that will guide you through the recovery process.
I hope this helps!

I can't update my Graphic Card AMD Radeon HD 7670M

Hi Guys ,
i'm new Here ,i have Hp Pavilion G6 2332se ,it has AMD Radeon HD 7670M ,i tried to update it but it makes intel hd graphics 4000 not defined ,and this is the result when i update the card

Hi @AhmedZizo
Welcome to the HP Support Forums!
I understand that you are having trouble after trying to update your video driver for the AMD Radeon 7670M. I am happy to assist you with this. Firstly can you verify the full product number for your notebook, for some reason I did not see that version on the list when I looked for it. Also the operating system in use would be helpful. Please read the following documents if you need help in finding those.
How Do I Find My Model Number or Product Number?
Is the Windows Version on My Computer 32-bit or 64-bit?
Once I have that I can find the correct driver page for you.
You can check out this page as an FYI.
Switchable Graphics on Notebooks Configured with Intel and ATI GPUs
Another choice would be to try to either reload your old drivers from the recovery partition, or try a system restore in the hopes that may be all that is necessary. If you use the System Recovery option just be sure you are only choosing to reload drivers. A full recovery would reimage your hard drive. Just in case you may wish to back up any data on your notebook first.
