Why does my powerbook screen go negative, then rain pixels

So this has been happening for a bit now. My room mate turns on his computer and the screen is fine. After about 15 miuntes the screen image basically goes negative for a minute or so. After that little pixels begin to rain down until the entire screen is pixelated.
When it is pixelated I can use an external monitor to view my desktop perfectly, which eliminates the graphics card as the issue in my opinion. 
Has anyone ran into this issue before, or know someone who has? 
I feel as though he may have himself a very portable desktop now.

Boot in safe mode and try to recreate the issue and report here.

  • Why does my powerbook screen look inverted(256 colors)

    when I powered off my PB after it locked up
    and re started it goes to the mac OS blue screen and starts
    loading normally,then all of a sudden it goes goes grey and inverts
    all images loading on the desktop. When I check the displays
    screen under system pref. it had my colors listed at 256. So
    I switch it to millions and it still did not return to full color.
    I suspect I'm in some type of safe mode.
    Can someone tell me how to return to my full color resolution
    screen. thanks in advance

    Open the Universal Access pane of System Preferences, and then on the Seeing tab. Push the button by Black on White to return to full color. You can also toggle this setting by pushing the Option, Control, Command, and 8 keys simultaneously.

  • Why does the apple icon come on then off then a white screen appears?

    Why does the apple icon come on then off then a white screen appears? 

    Try:
    - iOS: Not responding or does not turn on
    - If not successful and you can't fully turn the iPod fully off, let the battery fully drain. After charging for an least an hour try the above again.
    - If still not successful that indicates a hardware problem and an appointment at the Genius Bar of an Apple store is in order.

  • Why does my Imac screen slide and I lose my screen?  It goes back to my desktop.  Then sometimes my screen goes to full screen and I don't know how to get out of it.

    Why does my Imac screen slide and I lose my screen ~ It goes back to my desktop.
    Then sometimes my screen goes to full screen without me doing any commands, and I don't know how to get out of it without going to force quit and starting all over. 

    Hi,
    When it goes full screen try moving the mouse up to top right of scren & see if there a double diagonal Arrow to click on.
    On the other see if it's the silly implentation of Spaces/Mission Control/Expose in ML...

  • Why does my lock screen glow green?

    Why does my lock screen glow green? It does it quite often, no affects on  the phone.

    Basic troubleshooting from the User's Guide is reset, restart, restore (first from backup then as new).  Try each of these in order until the issue is resolved.

    I've tried contacting Adobe, but they're ways of contacting them are a pain in the ***. The chat doesn't work and I'm on hold forever when I call.

    Why does Adobe promise return calls and then not do so?   To avoid talking with customers?

    Thanks for your reply - unfortunately I have talked with an Adobe
    representative in India and their action is to put one on hold
    indefinitely.  I am annoyed  because I paid an additional $60 to them 
    for no reason.  Appreciate your comment.

  • Why does the video window keep minimising then opening again?

    I'm slowly working through all the problems I am having with my laptop, and this one is just a bit weird - nothing more than an inconvenience, but it sorts itself out.
    If i am watching a video / TV show in iTunes (opened in new window, not in iTunes window) and am doing something else (eg using safari), then i try to move the movie (as it is now not the active window), sometimes it moves, sometimes it pauses for no reason (I am clicking the bar with the videos name in) and sometimes it freezes, the video window minimises then instantly comes back up from the dock...
    Does anyone know why it may be doing this?

    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.
    *https://support.mozilla.com/kb/Safe+Mode
    This can be a problem with session restore.<br />
    Firefox stores session data every 10 seconds to make it possible to restore a crashed session.<br />
    If you have (security) software that interferes with that or have many tabs open then that cause cause a delay.<br />
    You can try to increase the session store saving interval to see if that has any effect on the freezes.

  • Why does new 5s screen look like the old 4?

    We just bought and backed up two new 5s replacing iphone 4. Why does one new 5s screen look like the old 4 iphone. One phone shows new version, one is still old. I have downloaded and backed up twice, same thing happens. Used icloud to backup.

    Sure, here's two photos, LP5 is the old screen style, NP5 is the correct screen. Note the differences?
