My computer screen keeps flikering
my screen keeps flasing in every 2 secoonds, happens even on startups and when i turn off my computer!!! can someone pls help me and my resolution is 1440*900,and refresh rate is 60.. thats the only option.
OK that sound like the video card and in the case of an Macbook, that site on the mother board. This will possible mean you have to replace the whole mother board and that is pretty expensive if you don't have an Apple Care pack. back up and get to a service center asap. If it was just parts of a window the where breaking up when you drag a window around, then it could be the firmware and easily fixed.

Wht does my computer screen keeps going dark?
Why does my computer screen keep going dark?
Good. This means that, in your existing account, a setting is bad or .plist file is corrupt. As identifying the rascal may take time, my suggestion is to move data to the new account, must be with administrative privileges. As the contents of each account is unavailable to the other, there are two methods:
- if you have a backup on an external disk, as you should (if not, consider this seriously, do not count on good behavior of hard disks), make a last backup on the existing account, and restore in the other account; when ready, delete the old (buggy) account
- if not, save your settings unto a flash drive; this is a limited backup just to avoid putting back settings for Mail etc. I am satisfied with iBackup (grapefruit.ch), but there are other backup utilitites, Time Machine, for example; TM does not allow limited backup, it works if you have a large external disk. If backup disk is not available, move files to shared folder, which is visibile from both accounts, and from there to the new account.
May seem difficult, in fact it is not. You must just move data from one account to another. Now, take care to new apps you install or new functions you activate. When you notice something strange, that may be the cause of this behavior. -
Hello there:
Hoping someone can help. I have been having problems with a shaky computer screen. It doesn't do it all the time, but it could be when I'm working on a Word doc, Excel doc or even in Dreamweaver.
I've heard it could possibly be static electricity, so removed anything on my desk that could be causing this. But nothing has worked.
Does anyone have any ideas.
Thanks much,
SusanI'm not what OS you are running on your intel core duo???
However, please tell us what the computer is, an iMac, a laptop or what, so I can ask the Hosts to move your post to the proper forum. -
My computer (Macbook) was working fine this am. I left it for an hour and then came back and the screen was black (always does that as the screensaver hardly ever works). I moved the mouse to wake it up and everything was normal. I went to adjust the volume and the screen went blank and the main page with the box where I put my password in when I first start my comp appeared. I put my password in and everything was normal again. I opened a window in Safari and before it loaded completely the same thing happened, the screen went blank and went back to the password box. Does anyone know why this is happening? I don't have an external hard drive or any blank flash drives so I can't back anything up right now and am afraid I'm going to lose everything. Thank you
Sounds like hardware failure, called boot loop. Call Apple and or go on apple.com and make Genius Bar appointment to have your iphone reviewed by a Tech. Provided you iphone shows no physical or liquid damage they will take care of you, or if you have Apple Care Plus

My iMac screen keeps showing pixels of previously opened documents and Safari tabs and hour or two after closing them.
Even when I swipe to the dashboard the outlines are still there when I know they should not be.
The shadow of those opened documents are still there hours later after shutting down and restarting my computer.
What is happening and what shall I do? Thanks in advance.Not much to go on in your product info, but maybe this will help: iMac (27-inch): AMD Radeon 6970M Video Card Replacement Program. If not, then it's time to visit an Apple repair station.

My imac screen works fine but it keeps flikering and freezing whats wrong with it
my imac screen works fine but it keeps flikering and freezing whats wrong with it? theres no crack or problem with it it just freeze's ande flikers
It sounds as if your graphics chip (on the logic board) is failing. The other answer could be that your screen is not well, but I lean more towards the graphics chip. If you have Apple care or are still under warranty, call Apple.

I update the FF browser few days ago and since then whenever I use the FF browser my screen starts flikering. I am a web developer by profession and I relied heavily on FF for many of my works. Any good solution for this issue ?
Thanks in advance.

My 2007 MacBook Pro keeps receiving "you must restart you computer" screen upon start up
It all started when i was watching videos online and the screen froze. It did this a couple more times and in between these freezes the computer would occasionally freeze during start up while the gray wheel was spinning.
I was running lion. i decided to reinstall snow leopard (dont ask why) and upon doing so ran into a few troubles such as the compter saying my log in password was incorrect. after sorting all this the computer was fine for a day or so til it froze again, this time while watching a video from a usb flash drive.
from that moment on, i have not been able to get past the "you must restart your computer" screen. I have tried everything i have found in this forum that relates to my problem to no avail.
i have booted in safe mode, booted in terminal mode and checked the hd which is said to be ok, i have resest the ram, and i have tried to boot from install disk (both dvd and usb flash drive)
after i check the hd in terminal, i typed "exit" to reboot and received this message:
cannot get audit control port
Warning: audit space low <5% free
systemShutdown false
along with others

Satellite A300 screen keeps jumping up and down
Hi,
What is on my screen keeps jumping up and down, any thoughts, is this a problem with video card in Satellite A300?I have tried to install the display driver from the European website. During uninstallation I got a messgae to say failures occurred during uninstallation, and then during installation I got the message of Install package failure!
I have my external monitor now connected to laptop, but in personalising display settings, I cannot get my computer to recognise that I have two monitors now, as both keep coming up with number 1 (Multiple Monitors) on ATI Mobility Radeon HD 3650, and they both have that degraded view, a bit like in safe mode.
So in checking of device manager under display adapters I have:
ATI Mobility Radeon HD3650
and under Sound, video and game controllers I have:
High Definition Audio Device
Realtek High Definition Audio
In this whole process I deleted a file that was previously here called
ATI HMD...
should I resinstall this?
So I'm not sure if the new display driver has been installed? help. -
MacBook Computer Name Keeps Changing
Recently my Mac computer name keeps changing. It's the normal name, but with a number at the end that keeps incrementing. How can I stop this?
I'm not sure if it's something to do with the fact I had a partition for the public OS X Yosemite, which I have now deleted.
Any ideas? Thanks.I was having the same problem for awhile, even contacted support so they could screen share and see what I meant.
What I ended up doing was correcting the name and then unchecking all the boxes in Sharing. Open up Airport Utility and reset the router (basically I changed my password only because that's the easiest way to make it update). Go back into Sharing and recheck the sharing options that you had previously. Viola!
So far it's been a week now and my computer name has not changed. Hope this helps -
Screen Keeps Freezing & Sleep Wake issues
I have a 17" Macbook Pro and the screen keeps freezing. The computer doesnt freeze because when i depress the volume buttons i can still hear the beeps or when i hit F8 music from my itunes starts to play.
Also, 60% of the time when my computer goes to sleep I get a blank screen when i try to wake it. When this happens i have to close the screen for about 2 mins until the computer re-falls asleep. Once this happens I can then wake it up.
any ideas on the causes of these two issues?Hello
> he told me that the laptop is pretty warm.
Probably this happens due a higher internal temperature

I am recording my computer screen with an elgato game capture card. When I play the unedited footage on my own computer, it is clear and crisp. When I import the footage into premiere elements, it becomes blurry. It becomes even blurrier when I save the edited video. How do I keep the video clear? How do I fix it?
Betharoo
Thanks for the reply.
Please check out John T. Smith's information.
At this point, if you could tell us the file extension of the file involved, that would give us a start while you are
gathering the rest of the details.
You can easily get some information for us from Properties for your imported video that is blurry in the Editor.
1. Click on Expert to get into the Expert workspace of Premiere Elements 13
2. If you have not already, import your file into the program using Add Media/Files & Folder/Project Assets.
3. Open Project Assets to see a thumbnail for the video that you just imported. Right click that thumbnail,
and select and click on Properties from the menu that opens.
4. Tell us what is listed there is Properties - it should look something like this one which is specific for one of my wmv files.
Your information will be specific to the file that you right clicked in your Project Assets.
From what you have written so far, yours should show
Image Size 1920 x 1080
Frame Rate either 59.94 or 60
Also, please go to Edit Menu/Project Settings/General, and tell us what you see for
Editing Mode
Timebase
Frame Size
Pixel Aspect Ratio
even if the fields look grayed out.
Your project settings may be contributing your Edit area previewing problems.
All of the above will keep us moving forward in the troubleshooting.
Thanks.
