BFG FX5900 Graphics (Strange Lines)

I've installed 3 of the same cards on this K72NG-ISLR motherboard, and i get the same result.  Verticle Lines with little dots in them flashing.  This happends at the Main BIOS screen and during the Windowsxp Logo testing startup screen.  After that is much better, but still have shadowing, lines around the mouse pointer, and some corrupted Icons on the desktop in windows.  I have Latest bios release 1.6 Award, and i'm not sure if there's a hardware update for the 128meg CFG FX5900 yet.
As anyone else here had similar problems?  Please post remedies, or shed some light on the subject.
Thanks.

I've seen screens like that due to a seating problem with the card.
As you describe, logging out, or a restart would restore the screen.
When I first saw this behavior, it was when the machine was awakened from Sleep......
Reseat the card, and when tightening the hold down screw, make sure the card does not pull over to one side as the screw is tightened.
The clockwise turn of the screw can move the card over (down in the G5) which can cause some pins to have weak contact.
Also take care that the card is not tilted forward at all.
Pulling on the cables can cause the connectors toward the rear of the card to slightly lift out of the slot.
If, after cleaning, and adjusting the seating of the card, the symptoms continue, or especially if they worsen, the card may be considered compromised.
I would also try running the machine in a new user account just to be sure that a software problem within the account isn't culprit.

  • Strange lines on my screen

    Recently I have noticed strange lines appearing on the screen of my MacBook Pro - they appear and disappear randomly.  I have noticed it especially on and around icons, as well as around the edges of Finder windows.  Today it escalated to the point where I couldn't see anything on the screen (see attached screenshot).  My computer is about 3 years old and I haven't had any problems with it.
    I just recently upgraded to Mavericks - could this have anything to do with it?  The problem started shortly thereafter.
    Please help!!

    Disabling "Automatic Graphics Switching" seems to work to resolve this problem.

  • Strange lines in pages while browsing (Render errors?)

    Strange lines that look like render errors show up while browsing, and seem to be triggered by moving the mouse & scrolling. I've also noticed that this problem seems to only occur when the browser is maximized. Rolling over links makes the link text pop ot from behind the lines.

    hello, please try [[Upgrade your graphics drivers to use hardware acceleration and WebGL|updating your graphics driver]] - this should be the right link for your system: www.geforce.com/drivers/results/56378
    or in case this doesn't solve the issue, disable hardware acceleration in ''firefox > options > advanced > general''.

  • Sporadic strange lines in my screen

    It happens sometimes that strange lines appear in my screen for some miliseconds XD. It's a short time but it finishes being unconfortable.
    I'm using xorg with xf86-video-intel, i've got direct rendering and i'm using the gnome desktop. Any idea?

    i have the same problem. about a day after i got my ipod little lines appeared on the screen, when i have my ipod on it looks like i have little lines of water on the screen so it makes the pixles look messed up. i guess they must be sratches but i dont want a big protective case for my ipod. any suggestions?

  • Strange lines appearing behind itunes

    I went away for the holidays, and when I got back I booted up my 2006 iMac. Today for the first time, there are strange lines appearing behind iTunes whenever it is open but not the active window. I tried quitting and restarting iTunes, but the lines come back. I wish I could upload a screen shot of what this looks like on my desktop, it's very weird. It does not happen behind any other program window. Only iTunes. The lines appear as if they are extensions of the iTunes window formatting, in line with the side bars, etc. Has anyone else experienced this? Any tips for getting it to quit?

    I just wanted to add that I am also seeing the same problem: strange lines around the borders of the iTunes window. The most obvious ones are a set of four vertical lines running parallel to both sides of the iTunes window, although there are other strange bits as well, mostly around the top corners of the window, as well as a single thin horizontal line above the top of the iTunes window. These unusual lines started appearing "out of the blue" sometime in the past few weeks -- as in, not right after an update or any other configuration change to my mac... The only change I can say I did recently was to update to OS 10.6.6, although I know others who are running 10.6.6 and aren't having this issue with iTunes. I also wanted to add that in my case, I only see these strange lines when iTunes is the active window. Further to that, updating to iTunes 10.1.2 does not fix the problem, unfortunately.

  • Strange lines

    I create tutorials for a company. Ever since I started using
    Adobe Captivate 3 (over a year), strange lines appear in the
    rendered version of certain screen shots. These lines only appear
    in a consistent group of screen shots. I have tried every angle I
    could think of to get rid of them including:
    Exporting the existing backgrounds and inserting them into a
    new project.
    Taking new screen shots.
    Importing the project into Flash 8.
    Pulling out my hair.
    Again, these lines do not appear in the project until I
    render it into a flash file and run it.

    Welcome to our community, Scoot
    Have you tried the following? Right-click the slides
    exhibiting the behavior and choose Properties. Then adjust the
    Quality. Perhaps JPEG or something else.
    Cheers... Rick

  • Strange lines in JPG export. Artifacts?

    Hi guys,
    I've been having a problem recently exporting files as jpgs. I have a template for my blog -- one for a horizontal image and one for two verticals. I export these as JPG high at 72ppi.
    I've started seeing strange lines form on certain files. They're never in the same place twice and flipping anti-aliasing on and off doesn't change anything. I've created several different templates using different sizes and export resolutions and I'm still getting these lines. Any help would be appreciated.
    I've included a link to the original file without the red circles.

    The lines on my iPhone 2G are still there after it happend and after posting to this thread 3 months ago. There is no software solution for sure. It seems that, according to the following link:
    http://www.modmyi.com/forums/general-iphone-chat/410391-grey-lines-iphone-displa y.html
    2G iPhone users have to buy/install the entire assembly (glass, digitizer, LCD)
    3G iPhone users can buy/install the LCD only.
    Or make use of the warranty service...

  • Strange line on my homepage

    Help. I can't get this strange line off my home page as it appears in Safari or any other browser. However, when it is open in iWeb, the line does not appear no matter what I do. Here is my url: http://web.mac.com/kerririchardson

    It looks like iweb generated a different CSS for the Welcome page than other page.
    You can fix that by changing the Welcome.css file, Welcome.css is located in Welcome_files folder.
    Open it with a text editor and search for: graphicshape_styledefault
    In that block, you see: *border: 1px #751b96 solid;*
    You either remove it or change 1px --> 0px

  • Speckles in shadows AND strange lines in highlights

    I've found that I get strange lines in highlights and intense constellations of speckles in shadows when changing treatment from colour to greyscale and back to colour in Lightroom 2.5. A reimported copy of the image will not display the effect. If I change nothing else, switching to library view makes the artifacts go away, back to develop and they reappear. If I change anything else, they are there to stay. The exported file includes the artifacts. My CPU is an Athlon XP (so no SSE2), OS is Windows XP SP3 32-bit. Images are from a Sony A700 fw v.4. Just thought I'd see if anyone else who wasn't on a PowerPC Mac is having these issues with this release as well?

    Yes. At least one more non-Power PC user reported this.

  • Strange lines on my screen - graphics card issue?

    Hi!
    I'm totally new in this forum but from what I've read you guys really knows a lot about macs.
    I have experienced some flickering lines appearing on my screen especially when watching graphic intensive webpages or changing resolution in games or switching to full screen on flash-based video websites. These lines are often accompanied by a low twittering noise from the computer. Sometimes it's just a few lines but sometimes the whole screen is covered. Logging off will fix the problem temporarily.
    My theory is that my graphics card is giving up. What do you think? Is there something to do about it other than to change the card?
    I have run tech tool 5 without any errors.
    I would really appreciate some help. I took a pic of the screen with my iPhone but I suppose I can't upload it here for you to see?

  • Strange line/graphic in Finder

    Recently I noticed a wierd thing in my finder windows.
    On the top left, to the left of the Red icon, I see a jagged line and three dots.  See attached.
    Any ideas?
    Thanks, Jay

    Same thing just showed up randomly.  Any suggestions?

  • Strange lines when exporting from Illustrator

    I am having an issue that's driving me crazy, I've tried everything and I still can't figure out why it's doing this.
    I created a template in Illustrator,  very basic,  just some 1 inch circles.   The goal is to color them in different color palettes and then save it as a PDF.   In Illustrator,  they show up completely fine,  the pattern fills sometimes have those little seam lines but those don't show up at 100% so I'm not worried about that.
    My issue is that when I bring these graphics into Photoshop,  these little white lines appear in random places,   these are not pattern seam lines and there's no reason I can think of for them to be there.  I figured it may have been a corrupt file,  so I started from scratch and the lines are still there.  I've tried  copying it directly from Illustrator and pasting it into Photoshop,  same issue.  Saving as a TIFF,  same issue.
    Here's an example of the line I'm talking about,  it's faint but noticeable on my screen,   any idea what might be causing this?
    http://img.photobucket.com/albums/v648/hazelsmrf/line.jpg
    The only thing I can think of is that when I turn off all pattern fills and only use solid color fills,  these lines don't show up.  I'm not sure why a pattern fill on a circle two circles away would cause a line to show up on a solid colored circle that's completely unrelated to the pattern fill though.   I am using CS5.

    My Illustrator is fully up to date so that doesn't seem to be the issue.
    I loaded the PDF into Acrobat reader and those lines don't show up there,  they only show up in Photoshop,  strange?
    How I've brought it into Photoshop:  save as,  PDF,  or Tiff,  these didn't work.
    Copied it directly from AI into PS,  did not work.
    Saved as .AI and loaded that into PS,  did not work.
    I just tried it as PSD and it worked!  However I've not been able to duplicate that because every time I've tried to export it to PSD since then it says I don't have enough memory,  argh.   Not sure why it worked the first time and not after.
    Oh and the pattern fills were created with a blank no fill square on the bottom,  then a color filled square on top,  and then a few circles in a diagonal to make a polka dot pattern. Nothing goes past the square,  there's nothing in outline mode to show why it would do this.

  • Images in the screen corrupted by some strange lines ...

    Hi,
    I have many troubles concerning the display on my MacBookPro. Often, the image on the screen is corrupted by black lines and some strange colour patterns. When I use Tiger on the same machine everything is fine. I agree that with the version 10.5.2 the situation is a bit better tan with the 10.5.1, but anyway, this is not acceptable from Apple. When I disable the Quartz Extreme (via a tool in the developer folder), everything is OK. Hey Apple, how to solve this?
    Best regards, Edo

    I think I solved the problem, but this is not good for Apple.
    I checked the hardware specification via the "Abour this Mac" ... and I discovered that my graphic card doesn't support the Quartz Extreme!!!! So, why my Leopard configuration is set to support this feature? I have found this link that for the moment, solved my problem
    http://www.macosxhints.com/article.php?story=20040724190553112
    I hope that Apple will fix this in the version 10.5.32323
    Regards

  • Every once in a while when I open my mail or a page I get nothing but strange lines of symbols.  Many of the symbols are black triangles with question marks in the center.  I completely reset it like new, but problem still exists

    Every once in a while when I open my mail or open a page I get lines of strange symbols like black triangles with question marks in the center.  I have reset the ipad2 to new condition but the problem still exists.

    A reset does not make tthe iPad "like new."
    First, let's ensure that we agree on just what is a Reset...
    Hold down the on/off switch and the Home button simultaneously until you see the Apple logo.  Ignore the "Slide to power off" text if it appears.  You will not lose any apps, data, music, movies, settings, etc.
    If the Reset doesn't work, try a Restore.  Note that it's nowhere near as quick as a Reset.  Connect via cable to the computer that you use for sync.  From iTunes, select the iPad/iPod and then select the Summary tab.  Follow directions for Restore and be sure to say "yes" to the backup.  You will be warned that all data (apps, music, movies, etc.) will be erased but, as the Restore finishes, you will be asked if you wish the contents of the backup to be copied to the iPad/iPod.  Again, say "yes."
    At the end of the basic Restore, you will be asked if you wish to sync the iPad/iPod.  As before, say "yes."  Note that that sync selection will disappear and the Restore will end if you do not respond within a reasonable time.  If that happens, only the apps that are part of the IOS will appear on your device.  Corrective action is simple -  choose manual "Sync" from the bottom right of iTunes.
    If you're unable to do the Restore, go into Recovery Mode per the instructions here.

  • Missing images in web gallery- strange lines??

    When I make a web gallery and publish to .mac a couple of images appear to be missing or are cropped.. its really odd.. everything looks fine in the preview. Also I sometimes get these really strange thin lines through my images.. I usually dont notice them until I get my prints done.. Has either of these happened to anyone? Thanks.

    nikinoo --
    In the past I've experienced the same problem with some web galleries. The problem went away after I quit Aperture & then opened it up again. I then went and republished the problem gallery without a hitch.
    I too have experienced lines running through my images, but it's been quite some time -- The upgrades that Apple has released appear to have corrected the problems. It might be helpful for you to list what printing settings you are using, there are tons of people here who should be able to help.
