My laptop screen is glitching and it becomes green with lines

THe screen when is moved flickers and the screen turns green with lines. And the laptop will freeze unable to do anything. Then when I shut it off and restart it makes these 3 beeping noises then stops and does these noises again.
it is a bad problem, but can anybody give me an estimate cost to repair this issue? Please and thank you!!!

Those three beeps indicate defective or bad RAM memory. If this is the only problem it is not very expensive (you can even install the RAM yourself), but as the screen is flickering too, I would recommend you to take your Mac to an Apple Store or reseller to see if the logic board is also affected.
The cost depends on the damaged parts. If it is only the RAM, it is not expensive, but if the logic board has to be replaced, it will be very expensive.

My G5 iMac has a screen color problem. The color is green with lines. What can I do to repar this? Sometimes the screen will freeze and I have to reboot the computer and the screen will be normal for up to 5-6 hours and then suddenly changes back to green

Try running in Safe mode. This leaves out some video drivers. Which results in machine not using advanced video hardware.

Blank (lighted, but black) screen with cursor at bootup

Iphone 5c screen flickering, pixelated and then becomes unresponsive

i got a replacement iphone 5c from apple about 4 months ago. my first 5c started flickering and eventually just gave up on me. apple had it for 2 weeks and sent back what i was told was a brand new 5c. Lucky for me as i was just passed my 1 yr warranty when i got it back. the first time i turned it on the screen flickered a few times but stopped. Now, the app icons jump around the screen and the screen gets so pixelated you can barely see the screen. After this, it will become completely unresponsive and wont even power off. Ive restored it three times now and nothing works. i feel really let down - i look after my phones and have always bought apple products. the 5c is the first apple product ive had so many issues with. To have a completely unusable phone after 4 months of getting it straight from Apple is a joke and to make things worse im out of my warranty. is there any way of fixing this or at least contacting apple to let them know whats
happened? the website just keeps redirecting me to various pages which are not helping at all.

Hello woothie,
It sounds like your screen is behaving unexpectedly and is not displaying your content correctly. If you had been restoring from a backup, I would next test it out after having backed up and restored as new with this article:
How to erase your iOS device and then set it up as a new device or restore it from backups
If you had restored as new, or the issue persits, here is the number to call AppleCare directly:
Contact Apple for support and service

Need help with Leopard: screen saver glitch and very slow internet

I performed an erase and install leopard 10.5.1 on my upgraded G4 AGP Sawtooth Computer several times. Has anyone had the following 2 problems with leopard and any suggestions to solve them? Apple telephone support has not helped thus far. The Issues include:
1-Internet surfing (Safari and Firefox) is extremely slow worse than dial-up. I have verizon fios. Upgrading leopard to 10.5.3 and upgrading Safari did not help and took about 10 hours to download when it should have been quick.
2- A screen saver glitch: When I click on screen saver such as beach I get this message. " Screen saver "beach" did not load properly. Error Can't load bundle" When I click on the screen savers folder, there is nothing in it. Desktop pictures work fine.
Computer upgrades include:
Processor-OWC Mercury Extreme [email protected] 2MB L3 Cache
2GB memory
Two 120GB hardrives.
Firmware is updated.
Thus far, all this was done:
Apple exchanged install disk. Same results with new disk.
I ran disk utility and everything is ok including permissions.
I performed a safe boot with apple support.
I Threw away cache folder and com.apple.safari.plist
Tried firefox with same very slow surfing results.
I even checked file system structure problem fsck -yf. Everything was ok
Thanks in advance for any suggestions.

Althought the behavior is the same in all three accounts, if all are working accounts I would suspect there is something all of them have installed that could be the source of the problem. Try creating a new admin account, and leave it just the way Apple creates it--don't add anything nor modify it in any way. Log into that account and see if it works correctly.
If that account is also misbehaving, try restarting, and when you hear the chime hold down the Shift key so that you boot into Safe Mode (you'll see a notice in the splash screen about being in Safe Mode). The boot will take longer (perhaps even considerably longer) as the system runs disk repair, empties some caches, disables all third party startup items, as well as all Apple startup items not strictly necessary for the machine to run. See the menus and Dock now behave correctly.
Since the problem is evidently somewhat intermittent in nature it may take some patience to discover what is wrong. You might also disconnect everything that didn't come with the Mac, reboot, and use only the Apple keyboard and Apple mouse and run for a bit to see how that works. If you are using a third party mouse that required installing something that would be my guess as a "prime suspect" for the cause of the problems.

My 15" laptop screen is dark, but computer works fine with plug in large screen

I am not sure if I hit a key combo or something, but laptop screen is off. Laptop is on and works fine and I can see everything on large plugged in 27" screen, nothing on laptop. It is as if I accidentally hit a toggle switch combo to turn off laptop screen while leaving on a plugged-in screen, like you can on a PC when going between laptop and, for example, a projector. any ideas? I recently switched to mac after 20 years on a PC. New MacBook pro.

Hi, nope, tried that again just to be sure. Thanks though. The screen is completely black. Worked fine yesterday and last night.

Hi, I accidentally spilled water on my Mac Air on the very right side of the keyboard. After a few minutes, the screen turned white and a gray folder with a question mark came up and kept flashing. THEN IT DIED HELP.

After the screen turned white and the folder popped up, it just kept flashing. After a few minutes the screen just turned white completely and I could hear the noise of the drive. It just sat there still with the noise for a good few hours until the battery died and then my mac just shut down completely. I tried to see if the computer could charge, and it does charge. I just can not turn the computer on no matter what. It is dead. It might be the logic board or the drive...I'm hoping it won't cost me a new computer because I just got this 5 months ago....

Do not attempt to charge as that will only make the damage worse. You need to take the MacBook Air to an Apple store genius bar and have the technicians check and see what repair work is necessary. It only takes a very small amount of liquid to cause short circuits and damage.

Glitches and Load Speed Issues with Edge Animate Site

I recently created a website at www.goshowpro.com and am having some glitches and load issues occur and would appreciate any help or insight into the matter. The site loads relatively quickly on my computer and my hosting servers technical support system but when I show it to my client it takes anywhere from 15-20 seconds, even after I have cleared the cache and cookies. All my image files are 'gifs' as to alleviate memory usage and I don't know what else to do that I haven't tried yet. Additionally, when you go to the services page from the about page, the light beams don't connect to the lighting fixtures and the text is placed differently than what I initially had in Adobe Edge Animate before I published the files. And the facebook link doesn't go to facebook but to www.goshowpro.com/facebook.... (ie I get a 404 error) even though in the program I have the link set as www.facebook.com.... I don't know what else to do besides what I have been doing and would very much appreciate any insight into these issues.
I should also mention that I used more html files than I initially planned due to lack of support on creating complete animation functionality with Edge Animate. I would like to have everything on one page but I don't know if that would be possible with the current version of Adobe Edge Animate (1.0.1.204.22434). Thank you again for your help.

Hi, Mike-
Have you tried profiling? You can use Firefox's Firebug or Google Chrome Inspector to see what's taking so long to download.

My MacBook won't start up. After turn it on I get a grey screen with an apple in center and a circle below with lines around it and a blank bar below that. How can I get it to get beyond this screen?

MacBook won't start. After I power up, I get a light grey screen with an apple in the middle, a circle with lines moving around it and a blank grey bar below that. It won,t get beyond this. Please offer suggestions.

I have the exact same problem and waited it out and got to my homescreen. Whateve the problem is fried my bluetooth and my trackpad. I tried starting it again and couldn't even get to homescreen, it stayed on the bluescreen with the wheel of death. So, I took it to genius bar today. I was informed that my logic board is fried and it needs to be replaced. $300 repair that I'm looking at...

Restarted my Mac and a white screen appeared, remained, and a yellow triangle with an explanation point stating Start up disk full- Help!!!!

I updated a couple days ago to OS x Maverick, everything on my Mac was working fine after update. But, Than today When I went to do stuff on my Mac it was frozen. So, I turned it off. When i turned it back on, the apple icon was on the screen and you can see that it was loading, but after several seconds it went to a white/grayish screen and a yellow triangle with an explanation mark popped up with a warning saying that "startup disk is full" i clicked okay and the warning went away but the white screen remained. I did do a Command R and pulled up the utility disk where I did repair disk, and than permission to repair, but it did not work. I think i need to erase some files and so forth, but I cant get past the white screen and into the desktop in order to do get to files to delete. Please help!
Thank you

You should never, EVER let a conputer hard drive get completely full, EVER!
With Macs and OS X, you shouldn't let the hard drive get below 15 GBs or less of free data space.
If it does, it's time for some hard drive housecleaning.
Follow some of my tips for cleaning out, deleting and archiving data from your Mac's internal hard drive.
Have you emptied your iMac's Trash icon in the Dock?
If you use iPhoto, iPhoto has its own trash that needs to be emptied, also.
If you store images in other locations other than iPhoto, then you will have to weed through these to determine what to archive and what to delete.
If you use Apple Mail app, Apple Mail also has its own trash area that needs to be emptied, too!
Delete any old or no longer needed emails and/or archive to disc, flash drives or external hard drive, older emails you want to save.
Look through your other Mailboxes and other Mail categories to see If there is other mail you can archive and/or delete.
Other things you can do to gain space.
Once you have around 15 GBs regained, do a search, download and install OmniDisk Sweeper.
This app will help you locate files that you can move/archive and/or delete from your system.
STAY AWAY FROM DELETING ANY FILES FROM OS X SYSTEM FOLDER!
Look through your Documents folder and delete any type of old useless type files like "Read Me" type files.
Again, archive to disc, flash drives, ext. hard drives or delete any old documents you no longer use or immediately need.
Look in your Applications folder, if you have applications you haven't used in a long time, if the app doesn't have a dedicated uninstaller, then you can simply drag it into the OS X Trash icon. IF the application has an uninstaller app, then use it to completely delete the app from your Mac.
Download an app called OnyX for your version of OS X.
When you install and launch it, let it do its initial automatic tests, then go to the cleaning and maintenance tabs and run the maintenance tabs that let OnyX clean out all web browser cache files, web browser histories, system cache files, delete old error log files.
Typically, iTunes and iPhoto libraries are the biggest users of HD space.
move these files/data off of your internal drive to the external hard drive and deleted off of the internal hard drive.
If you have any other large folders of personal data or projects, these should be archived or moved, also, to the optical discs, flash drives or external hard drive and then either archived to disc and/or deleted off your internal hard drive.
Good Luck!

Over the past few days my adobe programs have been failing on me.

I have Mavericks, now when I am in dreamweaver certain buttons are glitches out and rainbow colours?? super confused...

Pavilion g7 laptop screen flashes colors and will not boot

When I power up my laptop, the screen flashes different colors and will not boot up

The service manual is for the G7 series notebook and is not exclusive to the g7-1368dx model. Different models within the G7 family uses different hardware and supports different hardware upgrade paths. This means that an item listed in the service manual is not necessarily supported for every model in the G7 family.
Is the notebook's product number A7A46UA?
If so, the motherboard this unit came with is the 649948-001 as listed in the service guide. All the parts for this unit can be found here.
I searched HP PartSurfer for the part number 669690-001, the A8 processor, and expanded the note at the bottom of the result page to see what units came with this processors. I reviewed three different models and each had the motherboard 649950-001.
The units that shipped with the A8 processor had a different motherboard than what the units that shipped with the A6 processor.
Due to A8 units having a different motherboard than the A6 units, I suspect that the motherboard your unit has does not actually support the A8 processor. Sorry.

Project screen when exported and burned becomes tiny

Hello,
I am working on a project in Adobe Encore CS4. The project appears to be fine when we preview in the program, though there is a thin black border around it. When we export it and burn it to a dvd something changes. We play it on regular dvd player and tv and the picture becomes tiny and there is a huge black border around it. My boss and I cannot for the life of us figure out what setting is causing this. My boss has done projects before and not had this problem. We have compared previous projects to this one and can't find any settings that are different. Any help you can offer would be appreciated.

This is aimed at Premiere Pro, but may help

Hi
This may be a disply issue try to connect a external monitor to your notebook and see if you get the display there.
You can connect to an external monitor via a VGA or HDMI connection. The usual process to transfer the video output to an external source is to hold down the fn key and press f4. Use the arrow keys to select 'Projector Only' and hit enter.
