Changed graphics cards, now doesn't detect monitors

*I changed graphics cards on a Mac Pro and now its not detecting the monitors despite booting OSX10.5!*
Mac Pro
2 Monitors
Replacing radeon card with a geforce 7300gt
Unplugged everything
replaced card
Plugged everything back in, power last.
Powered on
Monitors are blank (cannot detect signal, autocycling between analog/dvi searching for one)
I've tried plugging just one monitor in and just a mouse/keyboard.
I've tried reseating the card.
I've tried plugging the card into 16x slot #2.
*Whats so infuriating about this is the computer actual BOOTS!* The keyboard dvd eject button responds, and I can explore the contents of this Mac Pros hard drive through the local network.
Any ideas?
What am I doing wrong! ><

What is the video card you are installing? Is this an ATI 3870? If so did you read the installation instructions before installing? You were to install the software drivers before installing the card.
Also check that you got the Mac version of this card.

Changing Graphics Card Settings

Hi there
I have a 24 inch iMac and when I run Maya (the 3d software) the timeline does not show up at the bottom of the screen.
It works fine on my old G4 so what is the problem here?
I figure I need to change graphics card options somewhere but have no idea where to find them.
Please help!
THANKS

I use maya alot, the timeline will be nothing to do with your graphics, if it was the nothing would show up, just hold space to bring up your hotbox go to display / UI elements and make sure time slider is ticked on, if all else fails just trash your prefences and relaunch maya, im going to presume your not a professional maya user? just assuming since your using a iMac for it which isn't the best chose, also what version of maya do you have? learning edition, 7, 8 or older?

Uninstalled graphic card - now unit doesn't boot

I managed to uninstall my graphic card and when I restart my pc, the computer screen goes black and even though I go into safemode, it does not work. In SafeMode the screen is black except the blinking "_" in top left corner, Ive waited over 30 minutes on the "_" to continue, but in vain.
Please help me!

Hi
As far as I know this issue occurs because the unit cant boot.
Well, it could be possible that the HDD has a fault or the boot sector is damage.
You should try to boot from the CD and if it possible so you should recover the unit with the delivered recovery CD

LR screwed up after changing graphics card?

After successfully working with LR since version 4 over a long period with thousands of photos I now have a strange problem which I can´t find a solution for on my own.
What´s wrong?
-LR doesn´t show any images, neither thumbnails in import mode nor full images or thumbnails in development view
-There is only a grey area where the photo should be.
-Old photos or newly imported pics all have the same problem.
-switching between files causes loading progress with plausible duration, but the image does not appear
-Histogramm, Metadata etc. are shown correctly, but no image nowhere
-Photoshop/Camera RAW on the same computer with the very same files work without any problem
What did I try to fix it?
-renamed the catalog file and created a new one. No luck. Same effect while importing and after that in the development view only grey again...
-renamed the previews, no luck
-renamed the agprefs file to start with fresh settings which seemed to work because I had to set the user language and so on. But - no impact on the problem.
-searched the faq and several boards, discussions, Google. No answer. Only one user with the same problem, he also got no answer...
What I may have done to get into that kind of trouble:
-I changed my graphics card some time ago. I had a NVIDIA 9800 GT before and changed it to a NVIDIA 640GT.
-I took every OS update, NVIDIA driver update and Adobe CC/LR Update and did not use LR after a couple of such changes.
Some facts about my system:
-Win8, Core i7 920, 6GB RAM, SSD/HD with enough space
-LR 5.3 latest update
Please help. Thanks in advance.

I would first suspect the video driver. Video drivers can cause weird problems, sometimes affecting only one program.
Things I would do, many of which you may well already have done:
First off, set a system restore point, so you can recover what you do.
Check the video driver, and make sure it's the right one.
Try earlier versions of the driver. The NVIDIA 640GT is not new, and may work better on older drivers. My GTX 550 doesn't like the current drivers, and is significantly faster with earlier ones. You can also go into Device Manager and roll back the driver to previous versions. I don't update video drivers unless there's a reason: to fix a problem, say. New NVIDIA drivers are usually only to support new hardware.
Try removing the driver (in Device Manager, use Uninstall for the video card). That makes Windows default to a basic VGA driver, and then get Windows to update the driver (in device manager, update driver). That will get what Microsoft reckon is the latest driver, which is not generally what NVIDIA think is latest, but may be more stable.
If you've still got the old card, try that (just to check whether it is a video card issue).
Uninstall and reinstall LR.
I know that's the obvious stuff, which you've probably done.
PS - as ssprengel says, check the monitor profile. Definitely the first thing to do!

Loss of visual display wen changing graphics card

I want to change my graphic card on my dual 500 G4 (currently running on 10.4.11), however I am concerned that once the old card is out I will loose all visual display and therefore will not be abe to follow on-screen instructions when installing the new Driver. Is this a real problem? if so, how do I carry out this procedure?

I have installed cards whose instructions called for installing the new drivers before installing the new card. If your new card falls into that category, no problem.
If drivers need to be installed AFTER the new card is in place, I don't think there will be a problem either. OSX has pre-installed drivers for most cards already; they aren;t the newest but are usually functional. Even without drivers, most cards allow the pass-through of 2D video. Example: new drivers no longer provide graphics acceleration under OS9 any more, but the computer has usable 2D video in OS9. I think you will have no trouble with on-screen assistance.
For what its worth, this is the forum for the very late PowerMac G4s, the "Mirrored Drive Doors" model and the FireWire800. The older G4s get a separate forum here:
http://discussions.apple.com/category.jspa?categoryID=113
You can get help either place, though. The forum software doesn't make it obvious that the other forum is for the early models,

looks a little like a downgrade to me - the article doesn't really deal with downgrading to the 'original' MacPro (?wonderng why? - 5770 shot? and X1900 lying around?)
Never tried to downgrade... so I'm out.

Can I change graphic-card?

I have just bought the iBook G4 and thought I could connect it to my Apple Cinema Display 20-inch.
This was impossible because my iBook has a mini-VGA port while the Monitor is DVI.
Anybody who knows if it´s possible to change to the same card that is in the 12" Powerbook?
(the one with the DVI-mini port)
Will be thankful to any replys.

I'm relatively sure that you can't change the card w/o some major warranty voiding surgery and even if you could it might not work. As for the adapter mentioned above. It's described on the site as "Connects VGA/SVGA Monitor to DVI Card on Computer" which is not what you have. I'm don't know for sure, but I don't think you can drive the DVI from the current iBook w/ just an adapter unless the monitor or adapter (or of course the graphic card) has a signal processor for VGA to DVI and since you're limited to the mini-VGA port I think you need to buy a VGA>DVI converter box.
I'd like to know what you come up with.
Good Luck

Cannot change graphics card/Old preference pane

Just received my new Macbook Pro 2.53. Loaded up just great was able to use all the features, but after transferring all of my old data via ethernet I cannot change the graphics card mode! I no longer have the option to. I have the OLD 'Energy Saver' preference pane! I do not even have the larger graphics card under the system profiler.
Any ideas?
Running build 10.5.5 9F2114

After a lengthy call with a rep at applecare, checking this, sending that. He had me remove the battery, unplug the wall outlet and hold the power button for 7 seconds. Popped the battery back in, plugged in the AC and it's back!
It wasn't so much I had an "old energy saver" pane, but rather the new one wasn't recognizing the 2nd video card.

Where is the option where you can change graphics cards?

I got a new Macbook pro yesterday for $1,499.
Well I wanted to switch the graphics card so I went into System Preferences>Energy Saver.
The thing is, I thought it was in the Energy Saver option, but there is nothing about the Graphics cards.
How can I change the graphics card for my Macbook Pro?

If your MacBook Pro is one of the models with a dual graphics card, the option to switch between them is at the top of the Energy Saver window: Graphics: • Better battery life, or • Higher performance. The MacBook Pro models with dual graphics cards are: 15" (2.66 and 2.8 GHz) and 17" (2.8 GHz). The 13" and 15" (2.53 GHz) MacBook Pro models have a single graphics card - for these models you will not see the Graphics option in the Energy Saver window. Which model do you have?

Change graphics Card macbook pro, is it possible?

Hey, Im just wondering if it's possible to upgrade the graphics card on a macbook Pro, late 2011 model. if so, what's the price?

No, any attempt to remove or change components on the logic board will void the warranty...because Apple and authorized apple service centers will not attempt to do that.

MSI P7N SLI - PC Wont Boot - Video error code but changing graphics card no help

((Apologies, I think this should be in the forum for Intel Core 2 Duo/Quad boards))
Hi. Brief description of the issue.
Last Saturday there was fan noise. I ignored that, left the machine on, went out. By Sunday morning the machine had turned itself off. I opened it up, identified the problem as the graphics card fan, failed to fix but put the PC back on figuring I'd have to see about a new card soonish.
Later on it had turned itself off again. Got to bios with a system32 config error. I figured that was why it'd been shutting off and went through the long process of manual recovery from that. Turned the computer on, all good, played games.
Until I thought to check the GFX temp... 133 degrees Celcius. Turned it off right away, ordered replacement card - which has now arrived.
But the machine won't boot at all. I get one long tone then two short. This is the same with both the old and the new cards. Blue light comes on, all the fans come on, then the beeps.
But the 'long' isn't long like if it was a RAM issue. I'm googling AMI bios post codes and seeing 1 long + 2 short is a video error, but also that '3 beeps' is a memory problem.
I've swapped my RAM sticks around and tried each stick individually and get the same beep code.
I've reset the CMOS by holding in the button on the back for 5 seconds, with the power cable unplugged and after discharging the capacitors.
The only other suggestions I've found is that it could be a failure of the PSU to power the card. But it should be giving ample power.
Now I am stuck for ideas.
MSI P7N SLI, MS-7380
Intel Q6600
Antec Neopower Blue Modular PSU
Zotac 8800GT [OR Asus GTX 260 212]
OCZ Platinum 2GB (2*1) DDR2 800
Western Digital HDD
LiteOn DVD Rom
Windows XP

With a 94000GT (no power connector from PSU) the machine is now running.
But there's still a problem somewhere (and that's a pretty poor graphics card I don't want to be stuck with) so I'm still keen to find out what to do, or what's wrong.
My 650W Antec with 2 12 volt rails should have no issues powering the other cards.

Cannot change graphics card

I thought I had this fixed:
http://discussions.apple.com/thread.jspa?threadID=1755849&tstart=0
But now after this happening again, I cannot get the same results after repeating the same steps. Basically the section in the energy saver panel that dictates which card to use-- is missing and I'm stuck on the 9400M. The other card does not even show up in system profiler.

I had this problem too, after migrating from a hackintosh time machine backup. Also, I interrupted the out-of-the-box setup process, and when I resumed the set up various things were glitchy, got trapped in the wireless setup phase, had to force restart.
The symptom was that in the energy saver pane of system preferences, it didn't list the graphics options, and some text saying "this will require log out" or something like that was splayed over a couple of buttons, all glitchy-like.
Anyway, I did a clean install of OSX and all's well so far with the graphics card options now appearing in my energy saver control panel -- it's been a day. Haven't migrated again, probably won't. If it reappears I'll post back.

Changing graphics card used for Virtual Terminal

I currently have two Nvidia graphics cards (I'm using the official proprietary drivers in the arch repos) in my machine.
Recently I needed to switch to using the other card for desktop graphics. I managed to persuade X to use the other card by modifying ``/etc/X11/xorg.conf.d/20-nvidia.conf``so that ``BusID`` was explicitly set (to the other graphics card's BusID) in the ``Device`` section and restarting X.
However I've noticed that the Virtual terminals are still trying to use the graphics card that was being used on first boot. Is anyone aware of a way of forcing the other card to be used without rebooting (I can't reboot right now due to others being logged into my machine that are using it)?

Negative. If the Dell you bought does indeed only have PCI, and from what Google has shown me, that card is PCI-Express. They are not compatible.
If you like my post, or solution to your issue/question, go ahead and click on the little star by my name and/or accept the post as the Solution. It makes me happy.
I'm NOT an employee of Best Buy, or Geek Squad, though I did work as an Agent for a year 5 years ago. None of my posts are to be taken as the official stance that Best Buy will take on your situation. My advice is just that, advice.
Unfortunately, that's the bad luck of any electronic, there's going to be bad Apples... wait that's a horrible pun.
