Black and white stripes? Help!

Hello!
I confess I'm a PC user (with plans to get a Mac in the near future, if that redeems me). Therefore I'm not especially familiar with Mac and its operating system, and when a problem arises I'm pretty helpless. I work in a technology lab at my school, and one of our Macs is encountering a problem.
The computer is perpetually displaying black and white horizontal stripes, with a spattering of multicolored pixels all over. I've tried turning the computer off and back on again (because that's about the depth of my knowledge of fixing a problem on Macs), but the computer doesn't even seem to try to boot; almost immediately after pressing the power button, I'm greeted with these hostile little black and white stripes.
I've searched these forums trying to find a solution, but have been unable to find anything. Any help or suggestions would be sincerely appreciated!
Thanks! =)

While using my Iphone 5, all of a sudden black and white stripes where on the screen. I have tryed to turn the phone off and on again, but there are only the stripes. I can't use it, and nothing happens when I push the buttons. Can someone help me?

Try resetting your phone, hold the home and sleep/wake button down until the apple symbol comes up, then release. If that doesnt work, you may have damaged your phone and need to take it to an apple genius bar.

[SOLVED] xfce+slim, suspend to RAM causes black and white strips

I recently installed a fresh copy of Arch. When I click the "suspend to RAM" xfce button the screen turns off as it should, but when I try to resume I see 5 columns of black and white stripes (like a flattened checkerboard ). Alternatively when I click the "suspend to disk" (hibernate) button the screen turns black but the backlight is still on, the only way to get out of this state is to do a force shutdown with the button.
I don't know if this is just an xfce problem, or if slim is also part of the problem, but it doesn't hurt to let you guys know about that as well.
Reading about this problem somewhere else as a probably graphics driver issue, here's my graphics card:
NVIDIA Corporation G72M [Quadro NVS 110M/GeForce Go 7300] (rev a1)
and I installed the Nvidia nouveau driver from here. I didn't see anything on that page about this kind of issue.
I also tried to add "ck-launch-session dbus-launch" to my .xinitrc file, I knew it probably wasn't the solution but I wanted to try anyways. didn't work.
I also have 2 gigs of RAM and 3 gigs in swap partition.
What do you guys think?

I have a slight newbie question that's related to my problem: after installing pm-utils am I supposed to have a file /etc/pm/config.d/modules? I reread the docs on suspend and standby here and the instructions are implying I should already have such a file, (since they say to modify it rather than create it), but I've installed and reinstalled the pm-utils and don't have any file there.
It's kind of important too, since i'm thinking I should put my graphics driver as one of those suspended modules...
Edit: one more interesting tid bit, when I use "pm-suspend" in the tty command line (by disabling the slim service and never going to xfce) I suspend fine. I need to have root privileges but I can just use sudo. (this is another reason why it could be a graphics card issue or I guess a privileges issue, hmm)
Edit2: I just tried to login as root from slim and hitting the suspend button, but got the same issue. So it's likely not a privileges issue. Strange.

Yeah it's dead. Take it to an Apple Genius Bar and have it checked out. Then buy a new one.

Iphone start up screen black and white stripes

My iPhone 4S powers up with a black and white striped screen then goes black. If I do a reset, it will eventually come back, work properly, and then go black again. When plugged into power, with screen set never to sleep, it works.

That's a sign of a hardware fault.
make an appointment at the genius bar and have it looked at.

Iphone 4 screen is black and white stripes-.

all the sudden the screen of my iphone 4 won't turn on any more. It plays music. When I plug it to my computer it looks fine, but the screen is only black with horizontal white stripes. Anything I could do to repair it ?

That's a hardware failure. make an appointment at the genius bar.

My ipod's screen went all fuzzy! Then it came on with black and white stripes/lines (vertical). Now it won't come on! What's wrong with my ipod? PLEASE HELP!

PLEASE HELP!!!!

Try:
- iOS: Not responding or does not turn on
- Also try DFU mode after try recovery mode
How to put iPod touch / iPhone into DFU mode « Karthik's scribblings
- If not successful and you can't fully turn the iOS device fully off, let the battery fully drain. After charging for an least an hour try the above again.
- Try another cable
- Try on another computer
- If still not successful that usually indicates a hardware problem and an appointment at the Genius Bar of an Apple store is in order.

Original picture turns black and white when adding layer masks.

Creating a collage. Just placed a new object with a layer mask. Now I need to create a hue/saturation, levels adjustment layer and color balance adjustment layer all with masks. Ok, no problem, but when I do this, my original picture turns black and white. HELP!!! School project and has to be completed by Monday morning.
Thanks. Dawn

You haven't added a Hue/Saturation layer that's got Saturation turned all the way down, by chance?
It might be helpful if you'd capture a screen grab and post it here, showing your layers and channels panels. With a look at how things are organized knowledgeable folks here should be able to help or at least ask more direct questions.

URGENT HELP REQUIRED: HP PRINTER ONLY WORKING IN BLACK AND WHITE

Hi - really hoping somone can help..! Just updated all three Macs to new OSX Mavericks and now both HP printers 940c and 5510c both only print in black and white. Need to get them working in colour for my daughters school homework!!
Have seen all the forums saying look at printer settings, but none of the settings have the old OSX options turning black and white and colour on and off. It appears the drivers that were on the previous Mac software have been deleted or turned off by Apple..? WHY!! I wish I had not updated any of the Macs if I'd known I'd lose printing functionality!!!
Seems HP no longer provide drivers for these printers that are over 5 years old. Trouble is I've got hundreds of pounds worth of colour cartirdges already bought for them that I thought I'd use!!!!!!!!! Maybe I need to go back to a PC as at least you can print things!!! ;-)
Look forward to any helpful comments....
Thank all...

My new iPhone 5 has black and white lines on the screen. It's not been damaged. I've tried turning it off but this does not solve the problem? Please help. I can't find my answer on the Internet.

By far the most common problem hardware-wise seems to be scuffs on the aluminium. Yours is the first report of a faulty screen I've seen.
If you use the same Apple ID on both devices it'll sync whatever you want it to - music/apps/photos/messages/etc.
I've just switched from a Galaxy S3 to iPhone 5 (having already owned an iPad for a while) so I'm in a similar position!

Help! I need to know how to make photos black and white from color and leave one thing colored.

I am a new user. I have elements 6. I really want to take pic of flower that i shot in front
yard and change it to black and white and then erase the b/w flower to reveal the true
color of the flower underneath. I have had mixed ways advised to me but not successful
any way i try. Help please!

Hi,
You can use Smart brush. From tools panel on the left, select Smart brush tool and select Black & White category and select any effect which you wish and start painting over the area to be changed to B/W.To edit your adjustments, you can select Detailed smart brush if you feel more comfortable in using brush than Quick selection tool.

Watching Movies: iPod to TV- black and white and split screen. Help?

I have this cable: http://www.radioshack.com/product/index.jsp?productId=2994604
As you can see, the chord colors on that cable are red, green, and white. The places where the chords go in on my DVD player are yellow, red, and white. As you can tell, they don't go up. I connected them so the audio works fine, but the movie shows up ONLY in black and white, and the screen is split right down the middle. On my iPod, the 'Video Setting' do not fix this. I also have the iPod Classic 80 GB, for reference.
Help?

Help! Photoshop is in RGB mode but I can only paint in black and white

It seems like Photoshop is stuck in B&W. As soon as I open my document, it shows at the top that it is in RGB/8 mode. I've tried clicking Image>mode>RGB again just to be sure but it's already set to RGB. The document is one layer so there's no way another layer is affecting it. Does anyone have an idea what may be going on? I'd appreciate any help I can get!

If it says rgb/8 then it is in rgb 8 bit mode.
If your opening a file, it could be 1 or more of the channels are missing or a single channel is selected. Take a look at the channels panel and see if the RGB channels are there and RGB is selected.
{odds are this is not it as the name of the channel would replace RGB/8 ex. selecting the B channel would display Blue/8 instead of RGB/8}
Make sure your document is not in quickmask mode (hitting the q key switches between quickmask and normal mode)
{odds are this is not it as quickmask/8 would be displayed instead of rgb/8}
Make sure you don't have a mask selected
{Odds are this is not it as layer mask/8 would be displayed instead of RGB/8}
Take a look at your swatches and verify there are colors there and not shades of gray
{Odds are this is not true because RGB/8 is displayed}
And finally verify what adjustment layers are applied to the layers panel - Several adjustments are capable of changing the display to black and white while retaining the RGB/8 mode.
If none of this helps then post a screen shot of photoshop with the layers panel and the channels panel open. You can drag a panel away from the docked position to keep it open.
