Black and white blocks covering browser during download

I am getting black and white "blocks covering my entire or parts of my whole browser when I am either loading a page, typing, or clicking a button while I am downloading a file. This happens every time.

Start Firefox in <u>[[Safe Mode]]</u> to check if one of the extensions or if hardware acceleration is causing the problem (switch to the DEFAULT theme: Firefox/Tools > Add-ons > Appearance/Themes).
*Don't make any changes on the Safe mode start window.

If disabling hardware acceleration works then check if there is an update available for your graphics display driver.

Previously rock solid MacPro ('08) crashed and now will not boot up past a screen of black, grey and white blocks covered in pink artefacts. Lion recently installed. Can this old warhorse be saved?

Yesterday the trusted and loyal MacPro froze and on reboot kept going straight to a screen which looks like a modern art collaboration between Kasparov, a robot and the ghost of Jackson Pollock. You can see the artwork in the pictures below.
Lion has recently been installed.
Main programmes used are Logic and Final Cut Pro.
I have taken the machine apart and dusted everything down, talked sternly to the ciruit boards, offered bribes to the CPU and even played it Salsa - I figured that this works in breaking the spirits of kidnappers, so it may work with the hard disk.
Nada.
There is a suspicion lingering that the computer was aware of a make or break week of editing coming up and decided to stop working in protest (it is getting on a bit), so I let it rest for a bit before trying another reboot.
Still no luck.
Short of going Basil Fawlty on it, is there anything I can do?
Help!

Time to put it aside to pasture.... the 8800GT has some known issues.
Better to replace it now while you can.
As for your system, w/o another gpu but I'd give 99.999% that you are fine.
For dust I juse a powerful 500W.

Other than the card working its way loose (hard to do) or the 6-pin aux power cable being loose etc.
Someone said that "post Lion" that many Mac Pro owners have not been able to use their OEM DVD with Apple Hardware Test (the test is on a hidden partition).
$249 isn't totally bad investment to keep it running.
Other than FBDIMMs self destructing and being fried @ temps above 72*C and having errors of some sort... which is also solvable.
And while / IF you can, make sure you have made bootable clone of your system and data, and have some kind of current TimeMachine backup.

Hortizontal black and white lines across web browser screen that appears and disappears but blocks usually 3/4 of web page, did not have with last version heard it might be my graphics card?

Since downloading Firefox 4, I will periodically get black and white horizontal lines that cover about 2/3 of the browser screen. There doesn't seem to be any trend to the website or areas it happens at, and will sometimes happen multiple times while scrolling through a large news article. The lines stay fixed to a certain area. The only way to get them to go away is to refresh the screen or if the page is big enough scroll to an area not affected and then scroll back. I've heard from someone that it might be my graphics card. My computer's a hand-me-down but not terribly old so it could be that the card is just old or bad, any other ideas?

No matter what website I am on all of a sudden the page will be covered in black and white lines and I can't see any of the page. What is happening and how do I fix it? It has only started since I loaded Firefox 4 this week.

I am very frustrated because I keep having my pages become covered completely in black and white lines. It has even happened on this page when I tried to use the drop down arrow by 'this happened'. I can sometimes read the page if I click over the area I want to read but this is not common. This has only been happening since I downloaded Firefox 4. I thought this would be a better version but now I am not so sure.

I do not want to download another virus program.. I do not believe it is a virus. I am running the full version of Norton 360 and it is doing a daily scan. I have Windows 7, 64 bit OS.
This is very irritating !! If I wanted Yahoo I would ask for it !

I've recently purchased an iMac and connected my HP Photosmart C4280 printer. The computer downloaded the driver software but the printer will only print in black and white.There doesn't seem to be anywhere to change this on the preferences menu. Any idea

I've recently purchased an iMac and connected up my HP Photosmart C4280printer. The computer downloaded the driver but the printer will only print in black and white. I've looked in preferences etc but cant see any way to change this. Any ideas??

Acrobat 9.31 / Browser Plugin - Printing Color PDF as Black and White?

I have an interesting issue for the masses. For a couple of our users (it encompasses both Windows XP x64 and Windows 7 x64), they are having an issue where when they attempt to print a PDF directly from Acrobat's browser plugin (in this case, IE8 is the browser), and attempt to print a color PDF to a color printer, the PDF comes out in black and white.
Here's some other consistents:
* Printing to a network printer, using the print driver Canon C5180-H1 Ver.2.0JM. The problem spans across two different print servers (we use a different one for XP clients and 7 clients, but the driver is the same)
* When the user clicks on "Print As Image", it does work (but doesn't look quite as good)
* When the user saves the PDF to a file and then opens it in the full Acrobat 9 Pro application, it does work (but this is a bit annoying)
Can anyone suggest some other things I should check and/or reasons that this might be happening? I'm at a total loss to explain it but will happily accept suggestions on ways to fix it.
Thanks!

Following up to see if anyone has some solid ideas on how this might be happening.
Thanks!

After I upgraded to Mavericks I was also having this message when I tried to update. There was a previous post about this problem which offered this simple solution which worked for me:

Got it! Thanx. What I did was go to my account, check that they had my new ID and Password which they did, then hit reset button. All fixed.

How can I prevent my screen getting covered with black and white lines while working on the internet which only happens with firefox and only go when I 'go back' or go down a page?

It happens as I surf - horizontal black and white lines particularly when I scroll down and only goes if I can go to a new page or go back a page. It is driving me crazy and only happens with firefox. I have disabled all plug ins but it still happens.

Black and white squares

Hello everyone,
I was on my mac browsing the internet and all of a sudden BIG black and white squares on my screen and this very loud noise so i had to force the computer to shutdown. can anyone please shed some light on this, is there something wrong with my mac its the first time its happened.

Yep. That's what they call "artifacts." In fact, it seems a textboox case of an overheating GPU:
"A common form of serious GPU artifact is a checkerboard pattern which covers the entire screen." (http://www.playtool.com/pages/artifacts/artifacts.html)
Do you hear the fan running? Try downloading an app like smcFanControl to speed up the fan. The noise you heard the first time could have been the fan going full speed OR the fan breaking --which in turn could have caused the logic board to overheat.
Placing the mini on a metal surface or on a laptop stand --preferably one with a fan-- may also help, at least for now.
Ideally, though, you should take the mini to the Genius Bar or an Apple certified technician.

Lightroom changes color photos to black and white error

When I import NEF files into LR, they initially display as Colour, then during the render process, LR changes them to black and white. It has never down this in the past, is there a reson why LR is doing this now? The photos are colour (as shown in Capture NX and Windows explorer), and during importing, I selected 'None' for the develop setting. Does anyone know what I am doing wrong? Thank You :-)
Particulars: Lightroom 2, Files: NEF (Nikon D300),OS: Windows XP Pro

Thanks Jao, much appreciated...I must of changed the develop setting...now that I recall, I did go into the Develop->Set Default Settings recently. The reset resolved the issue.
Thank You...CK

Video drivers issue (dual DVI monitors off bay :: one black and white and one color)

Hello,
I have tried everything to try to make these two monitors color. They are both relatively new Dell monitors. Both are DVI, both are connected to the latest Lenovo bay for my T430 laptop. Both worked fine after I initially installed both video drivers (Intel HD Graphics Driver for Windows 7 [64-bit]) and NVIDIA Optimus Display Driver for Windows 7 [64-bit]). Then out of nowhere one of them (Dell 1) decides it wants to be seen in black and white! I initially thought it was the monitor itself, but when swapping monitors (Dell 1, Dell 2) the other monitor (Dell 2) went black and white when plugged into the DVI formerly used by the Dell 1 monitor. Ok, so now it must be the DVI ports on the bay station (Lenovo) right? Nope. I had a tech bring me a second, brand new bay (identical). Same issue! So this leads me to the video drivers...
Does anyone have any idea. I disabled each driver and reenabled each to no avail. The drivers are the latest drivers downloaded directly from Lenovo's site. Checked the driver settings/monitor setting using both Windows 7 Professional and Nvidia to see if anything stood out. Nothing.
Any help would certainly be appreciated. Thank you in advance! :~)

I got a new laptop and when I plugged it into my docking station the external monitors were all in black & white. My old computer still worked fine without changing any settings on the monitors. I found that I needed to go into Control Panel \ NVidia Control Panel \ Display \ Adjust Desktop Color Settings, then select the monitor I wanted to adjust, then set the slider up for Digital Vibrance. For some reason on the new laptop the NVidia settings defaulted to 0 for this.

How can i make my officejet 6500a print in black and white only?

I just bought an officejet 6500a and I can't figure out how to make it print in black in white only. I print a lot of stuff that doesn't need color and want to save my ink. On some prints it gives me that option when I print. but for the most part it doesn't allow me to change to black and white on things i am printing off the web

Pages 30-34 of the user manual for the Officejet 6500A covers how to change print preferences for the printer with both Mac and Windows. It covers documents, brochures and photos and covers finding the gray scale option. Here is a link to that manual http://goo.gl/6J61R .
I hope that this helps.
