Is my mac pro's nVidia 8800gt dead. B&W lines across my screen only

Hi, I run a Mac Pro 2008 oct core system. The specs are as follows:
dual 2.8GHz quad core processors
Snow Leopard with all software updates
16GB RAM DDR2 (Pre-DDR3 mac) (apple certified RAM, so won't break my warranty)
Hard drives are set in two raid arrays, there are four 1.5 TB drives, each set to pairs of raid 0 for 3 TB drives. One raid array is set to time machine the other is my startup disc.
dual DVD RW drives
N-Videa 8800GT graphics card (Shipped with my mac)
using a DVI to HDMI adapter to connect to a 40" Samsung LCD TV as a monitor (has always worked flawlessly)
I have upgraded a lot of the parts myself and have a fair amount of knowledge of how to do my own upgrades. My system today crashed on me after waking from sleep mode and attempting to use the web. Now when I try rebooting it gives me a screen that is even lines of black and white, nothing else. I do get the Apple beep noise like normal so my assumption is it isn't going to be the memory. I have cleaned off, reseated, and tried different slots with my graphics card, and both DVI ports, same effect. I am pretty sure this is the graphics card demanding to be replaced, which I have considdered upgrading anyway in the past. Most of my computer activities involve watching HD quality movies and TV shows and playing games with high graphic requirements at maximum settings, so using a top of the line graphics card is to be expected.
What I am posting here for is just getting a confirmation that other people agree with me that this is the problem so I do not waste my money on a new graphics card. Please let me know opinions, I would like to have my computer running swimmingly in the near future. Thanks in advance, I appreciate any help I can get.

Most people often seem to think that after a system freeze they don't need to repair their boot drive.
Over the years, Disk Warrior stands out as indispensable.
ie, don't rely on the restart alone to repair and fix, and you probably don't want to trust and rely on just Apple First Aid.
Boot from another drive and run Apple First Aid followed by Disk Warrior; keep backups of your system you can boot from. Clone your system with SuperDuper. Clear out system caches.
You don't need to buy Apple RAM and its prices to have certified RAM, Crucial and others are fine. Sometimes even better.
I like a fsst, small, boot drive and keep it just to OS/Apps; everything else, media files, data, whatever, on other drives. Multiple backups and redundancy. TimeMachine doesn't benefit or perform any faster with RAID, I've tried just to see.
I would slice off some space for an emergency boot drive so you can OPTION boot to that and run First Aid and other maintenance.
Then worry about hardware, and maybe run some hardware tests.
And for a good "is it software or hardware" do a clearn install of Apple OS and updates (only) - needs less than 30GB.

Is my Mac Pro (early 2008) 8800GT dead?

Hi, I have an Early 2008 Mac Pro running OS X 10.8.4. I just upgraded to 10.8.4 a few days ago and left it alone. I noticed the other day that I couldn't wake it out of sleep, or rather, the display wouldn't come on and the fan on the 8800GT raced at full speed.
I've noticed in the past a few times that the Mac wouldn't come out of sleep mode (ever since 10.7 I think), so I haven't thought too much about it. However, I've gotten into the habit of SSH'ing into the box when this happens to try and trick it into waking up or just telling it to reboot. This time, however, it didn't go back to normal after a reboot.
What happens is that the 8800GT's fan runs at full speed even though the machine boots up healthy (I get startup sound and can remote desktop into it). I checked on System Information that everything is working fine, however, the machine no longer recognizes the display adapter.
I tried re-seating the card, no luck. I tried booting from the original OS X (10.5.x) DVD, no luck. I've tried full power off / unplug for several minutes, no luck.
Did my 8800GT card die? I never saw any strange fringe on the display like I've seen others on the forums mention. In fact, it worked like a charm until this happened. I was suspect of the 10.8.4 upgrade, however, booting from the installation DVD doesn't make a difference which makes me think that might not be right. I have seen suggestions of PRAM or SMC reset, but from reading up on the purpose of those non-volatiles, it doesn't sound like what I'm seeing. Unfortunately, I do not have any other PCIe video cards to test with (Mac or PC).
Before I drop a few hundred dollars on a replacement (or take the hassle of bringing it in to the Genius Bar), does anyone have any ideas?
I have not tried a different PCIe slot as the card literally hasn't been removed since purchase nor has the machine been moved or opened at all in the several months (last opening was to install an SSD).
Help!

I'd have to say yeah. I have a quad-core mac pro, 2.8 Xeon chips in there, and one day, boom, my card just died. No warning, nothing, just boom. so, I took it into the local A***e store only to find out they didn't have a lot of experience fixing mac pro's, so it took them a while. I asked them to replace it with a newer ATI 5770 card. I pointed to the card I wanted to replace it on the Apple store employee's iphone. What happened. I got a working GT 8800, because it was their policy to replace like with like. What the heck, man, seriously, what the heck?? I told you what I wanted and was willing to pony up to buy and...you didn't, and you charged me $320 for an old card, no refunds
the best they could give me was an apology.....
so, the moral of the story is, you can try taking it out, dusting, taking the plastic parts off the card and baking it, maybe that'll help get it working again. Or just go out and buy a newer graphics card, because it looks like this one's toast.

I have a 17" Macbook pro with flickering red and cyan(blue) lines across the screen. The issue disappears temporarily when I tap on the computer, and the problem does not occur when I use external display or try to screen capture the problem.

I purchased my Macbook (17") through a certified apple tecnition in August 2012, it was refurbished and the motherboard was completely replaced. I do a lot of photo editing, but I have been unable to do so because of the red vibrating lines that interrupt my screen. The issue disappears temporarily when I tap on the computer, and the problem does not occur when I use external display or try to screen capture the problem. I brought the computer back to the technition I purchased it from and he said that it was a problem with my fan, so I have two new fans but the issue is still occuring. He says he doesnt know whats wrong. Does anyone have any information on this issue?
Here is an image of the issue

I recommend having your Mac serviced by someone competent. A force sufficient to "blow apart" the fans was clearly excessive and may have damaged the display cable, as well as any number of other problems.
Dust is properly cleaned with a vacuum, preferably one designed for computer service, and they are not cheap.
Compressed air should never be used. It just blows dust everywhere, often into places where it can no longer be removed.

And never heard of one case of AHT finding or reporting a real GPU related problem.
It does sound like the graphic card and best way to know is to swap it out, even if you have a PC card around.

HT1430 Ipod touch (5th generation) w/ lines across the screen - now dead.

My son's Ipod touch (5th generation) had lines across the screen. I turned it off using the home + on/off button reset, but the apple never came back on. Now it seems to be dead. Not dropped, not completely drained, no water damage. Just dead. Any ideas?
I have also tried plugging it into my Macbook Pro, and iTunes does not find it.
ITunes is up to date.

Try:
- Reset the iOS device. Nothing will be lost
Reset iOS device: Hold down the On/Off button and the Home button at the same time for at
least ten seconds, until the Apple logo appears.
- Restore from backup. See:
iOS: How to back up
- Restore to factory settings/new iOS device.
If still problem, make an appointment at the Genius Bar of an Apple store since it appears you have a hardware problem.

November 2007 Mac Pro with NVIDIA Quadro 5600 Win only

Hi,
so I have a NVIDIA quadro 5600 graphics card (PNY model) from another machine and want to use it with my late 2007 Mac Pro since my ATI XT1900 is slowly dying, has some temperature issues.
I am only gonna use this machine for Windows and I am aware that the card won't work in MAC OS but I thought it should work just fine otherwise.
So I installed the card and connected a second PCI Express 6 pin power cable (in addition to the one that was there from my ATI card) from the mainboard (so from the unoccupied 6-pin connector next to the other one) to the card.
When I was switching on the machine, a buzzer sounds and apparently it means not enough power:
http://www3.pny.com/QuadroPDFs/5600PowerRequirements.pdf
so I thought there is something wrong with the mainboard 6-pin power connectors and used a molex y-adapter to directly connect the card to the power supply but with the same effect.
Next thing I tried to connect an external 200W power supply directly to the card, guessing that the MAC's power supply won't be enough (which it should...think 900W?) but still getting the buzzer sound.
Anyone tried this setup before or has some hints to how to resolve this issue?
If not, I guess I have to sell the card and look for an alternative - which card would be compatible for Windows use in my MAC Pro?
thank you all in advance,
Johannes Kohnle

I would concur, XP/Vista firmware reads two versions and most PC graphic cards have two versions embedded.
So hopefully with Mac's technical experience they should be able to do what Microsoft have been doing for years.
This is a well covered subject, we are all expecting something soon. Mr jobs told us so.
The reality is I guess, do Apple want to do it?
History dictates that they are not exactly ones for making Mac's upgradeable.
I too and I expect many others will seriously consider whether to upgrading again if the 8800GT for the Mac Pro 2006 /7 never materialises, mind you we could always place a pillow on it and use it as a seat.

Mac Pro with NVIDIA 8800 GT HD Playback

I just upgraded from my 2.7 GHz Dual G5 to a brand new Mac Pro Dual Quad 2.8 GHz Xeon (Early 2008) with the NVidia 8800 GT GPU. I'm having issues with HD (1080P) video playback in which the video stutters (would appear that the frame rate drops for a fraction of a second and then returns to normal). This is an intermittent problem and so I can rewind the video and watch the same scene again and it looks fine.
Is anyone else having this problem? Does anyone know of work-arounds? Are there any utilities to configure the NVidia 8800 GT video card like what ATI had for the X800 XT?
Thanks for any help!
Greg

I would add more memory, even if it doesn't seem like it is problem, OS X and apps will try to use what is available and use free/inactive memory as cache.

Glad you kept one drive 'as is' - if someone does want to test out or migrate always better to work off a cloned system until you know it works.
I try to have all the media on a stripped RAID, a dedicated boot drive with nothing else on it, which keeps things running smoothly.

Windows Vista 64 bit w/older 2 dual core 3.0ghz Mac Pro with NVIDIA 7300

I have read a variety of the posts that have appeared here on the use of Windows Vista 64 bits on a Mac Pro. I remain confused, and but want to do this. I have a Mac Pro purchased in the Spring of '07 with dual 3.0Ghz dual core Xeon cpus and 10gb of ram, using the NVIDIA GeForce 7300 GT and running 10.5.1, with multiple drives. I want to run the 64 bit version of Vista Ultimate to use my ram, and to gain the performance this box should offer. It appears that I have three options:
1. Boot Camp: I don't know if the drivers are available, seems like the new Mac Pro drivers probably would not work, even if I could find them, since I have an older Mac Pro with a pair of the dual core Xeon CPUs. Don't know if there is an alternate source than Apple for the drivers, or a way to get around the problem in boot camp.
2. Parallels: I do not believe that 64 bit apps are supported by Parallels
3. Fusion: Their web site says they support Win Vista 64 bit, but it is not clear to me on the web site where the drivers are obtained, or perhaps they are built in to Fusion. Will I get the performance and memory benefits in fusion? Or is the OSX virtual overhead so high that this is a fools errand?
I do a lot of video editing, and fully 95% of my life is in the Mac world, but I have individuals who send files for editing, and occasionally they require Windows tools, much to my chagrin. I also have a small number of programs that need Windows 64. I occasionally am required to do some development work, and would like to use this machine for that purpose if it can indeed run Win Vista 64bit. I have XP loaded on a more modest box andit is running fine when I need it, which isn't very often.
Any help, or successful experience in running Windows Ultimate 64 bit on this hardware, utilizing its resources would be greatly appreciated.

Here are my results after further digging online and from my own experience.
Here is the procedure:
1. Check whether your Mac has the 32-bit EFI or 64-bit EFI
http://www.ihackintosh.com/2009/08/snow-leopard-106-and-64-bit-what-you-need-to- know/
2. Create a Boot Camp (BC) partition for Windows 7 x64. Resize the partition size using the slider in the BC app. Follow the instruction, insert the Windows 7 disk and reboot.
3. This will load the PC partition which is FAT formatted for now. Choose the Boot Camp partition on which to install Win 7, but choose in the option to format that partition. It will automatically format it in NTFS. Otherwise, it will not install on that partition.
Note : A "OEM System Builder" Windows 7 64-bit Professional UPGRADE install without any issues what so ever. The upgrade disk is a full install. Read this for further information:
http://www.pcworld.com/article/174288/windows7_upgrade_madecheaper.html
4. Run windows, then insert the Snow Leopard disk. It will tell you your hardware cannot support x64 version. Do the following procedure to manually install the driver:

5. Then update Boot camp using Apple Software Update in Windows.
6. All hardware works fine except the sound. The sound only comes out of the internal speaker, even when headphone or speakers are plugged in the jack. Installing the Realtek High Definition Audio Codecs driver in order to fixe the problem. Shutdown and reboot to make it applicable. Try a second time if it still does not work:

When they say upgrade kit - it is just a standalone card right?
I don't need any other card to work with this?
Thanks Dan
ps - sorry for being a total tech novice

Re the statement in Barefeats' 2600 vs 8800 test that the latter's 3D advantage should also apply when used in pro apps using OpenGL (like After Effects preview), there are those who claim frame rate is mainly a result of the amount of RAM installed and not the video card used:
http://forums.creativecow.net/thread/2/919134 (older article though).
Then there is the finding by Barefeats - much to 8800 users' irritation/confusion - that the 8800 is not great at pro applications (that's the Harper10 link Hatter included).
I can only say I'm real happy with the 8800 and that it hasn't let me down once so far.

Mac Pro freeze at start up, pink wavy lines on display, tried disk, drive

My mac started freezing, so I tried to run disk warrior on my main hd and it failed. I restarted and now it won't start up.
When I start the computer, I get a grey screen with thin, wavy, pink horizontal lines about a 1/16 inch apart. The lines remain even when the apple comes up.
I can get the apple to come up and the spinning wheel, but it freezes after spinning for 30 sec.
I've tried:
Starting up from a retail osx disc
Starting up from a bootable firewire drive
Taking out all the hard drives and starting up from a disc and a drive.
Purging the PRAM
The best I can get it to do is freeze on the spinning wheel.
Any help would be greatly appreciated- thanks.

I put the hard drive back in and started it in verbose mode:
it freezes up around here:
jnl:unknown-dev: journal start/end pointers reset! (jnl 0x88ecf00;s 0x15ad200)

The last three lines repeat 4 times with different PBLKNUM and then it freezes.
Any idea what this indicates? Thanks.

Mac Pro - crashed and now won't start up, stripes on screen + kernel panic?

My computer apparently crashed while the screensaver was up (I was away for 10 or so mins, just Firefox and World of Warcraft in windowed mode running), as it was showing a black screen with a fuzzy whitish line along the top and was completely unresponsive. Unusual, but nothing to freak out about.. right?
So I did the on switch turn off/turn on routine and as soon as anything shows on the screen, I've got these black + white horizontal bars/stripes along the top 1/4 of my screen. The Apple Logo and the spinning progress bar have little fuzzy red spots on 'em. That's when it's time to freak out, as we're in "my computer done broke itself" territory. A few seconds of fuzzy progress bar and we get the wonderful "You need to restart your computer" message.
Fine.. restart.. same thing.
Reset the PRAM and SMC. Same thing.
Can't start up from external disks.. it just gives the same stripes + message.
I'm running a detailed hardware test (the hardware test loads but with the same stripes at the top and annoying blue/red vertical ones in the background to boot), and it's been running for about 80 minutes and is only 60% of the way through.
Anything else I can do, or do I have to drag the heavy thing to an Apple store and leave it there for a month? How in the world does a computer go from "working fine" to "completely broken" in 10 minutes?

More details:
The regular/non-extended Hardware Test returned no problems, despite taking hours for what was supposed to be a 3-5 minute test. I haven't dared run the extended.
I also tried removing third-party RAM and using the original configuration, then just the third-party and no Apple, etc.. It's not the RAM, as the problem is exactly the same.
I'm going to call up Apple support when I can, but just looking for other things I can check or possibly do until then, or just insight on what the problem could be.
Is it most likely the graphics card? Could it be an issue with the core hardware?

My Mac Book Pro suddenly gets stuck with weird horizontal colored lines across the screen, which will only go once I restart the laptop. What can I do?

Randomly while scrolling, the screen just goes beserk and gets stuck with random colored lines. And, the only way to get rid of this is to restart my entire computer. My laptop is about 3 years old now. Is this a sign of age or what? What can I do to run my laptop smoothly without turning it off and on every time it goes crazy?

Try resetting PRAM and SMC.
