Qosmio F10-124 - pixelated, flicks in white screen, then returns to normal

It seems that graphics hardware has failed on a pc bought in April 2005.

This took place in stages, starting from the time when I received
(1) an automatic download of windows updates and
(2) and upgrade Adobe.
In Sept 07. Don't know if it is at all related to dysfunction of screen.
The screen is best worked intermittently, with only access is possible using the external VGA port.

The latest display drivers Toshiba for the ADM operating system do not fix the problem.

In the last two days pixilation occurred in various parts of the screen to the external monitor, while the laptop was just empty, until that day that the external display display my work very well. Sometimes the laptop screen deflected in life and the pixilation has recently become more widespread. Occurrences of the task force for computer laptop screen were random.

I need to have the screen settings, such as the external monitor is a mirror of the laptop to do anything on the laptop screen.

Restart the PC has no effect.

Most recent symptoms are that the external display shows that the operating system has started, but there is an alignment problem causing a model to appear on the screen, and it's 'ghost '? with several iterations of all events of the screen on the entire width of the screen output. The laptop screen does not at all at the moment.

Someone has ideas, what could have caused it, or how to fix this?

The graphics card chip bad seems to work. Your question describes it really looks like a defect in the chip
But please note that this is only my personal hypothesis and if you want to be 100% sure what s wrong then you will need to contact the service provider in your country for a detailed audit.

In the worst cases, the motherboard needs to be replaced because the GPU chip is mounted on the motherboard and cannot be deleted.

  • White screen then freeze or Crash

    1 week ago, I launched my computer it took a while longer for the windows logo to go when he we finished it was a black screen for about 30 seconds then I logged and it was a white screen then after 10 minutes it froze, I left it for the rest of the day. The next day after the 10-minute froze then immediately crashed. I cannot get safe mode now.

    Take off the side cover and check that all connections (power cable to the fan cooling the CPU, motherboard, graphics card, etc.) are not loose and completely inserted, so that your him blow sheep from dust of the CPU fan and power supply. See if that helps.

    It runs from a floppy disk or CD and should eliminate or confirm if one or more of your memory

    sticks are bad or the values of the SPD in the BIOS are correct.

    Let it run for as long as you can: 2,4,6,8 or several hours (at least 3 full passes), if no errors at that time then your ram is OK.

    Hello;

    Let me welcome you on the HP forums!

    I read your post on startup problems and wanted to help.

    You should not have problems with a PC this new.

    My suggestion is that you contact the HP customer support to see about maintenance and options at your disposal under warranty replacement.  If HP is unable to repair it, then you should be able to insist on a replacement - no charge!

    If you live in the United States or the Canada, details are on this page: http://www8.hp.com/us/en/contact-hp/phone-assist.html#section1

    If you live elsewhere, contact details are on this page: http://www8.hp.com/us/en/contact-hp/ww-contact-us.html

    NOTE: once you get through, stay on the line until you are finally able to talk to someone ' one - it can take a while!

    Good luck

  • Cannot load games 'Titanic', 'Travel' - no message just a flicker on the screen, then the game stops. On "Death on the nile" error - latest version of directx. On 'Peril at End House' error - last need direct 3d.

    I have win7, Windows Home premium 64-bit on an HP Pavilion Elite I - 7 core intel and Gateway screen (fx2300). After the last update for windows and ATI, I had problems to read my games - some don't is not loading, some give me access violations, others do not go full-screen. Oh, now I can no longer adjust the resolution of my screen for anything other than the highest or lowest values acceptable (everthing in between is blocked).  I have supported the ATI update several times, but it takes to watch TV in hd. I worked with HP to install and reinstall the ATI update and update of the last window. Whenever errors are different on my games. Initially, they were access violations and some games would not work, I have the update and reinstall it and other games would get the access violation? Now I can't load games 'Titanic', 'Travel', 'Nancy Drew - lights camera curses'. -No message, just a flickering on the screen, then the game ends. On "Death on the nile" error - latest version of directx. On 'Peril at End House' error - last need direct 3d. I have directx 11. All my games worked at the beginning of April. .  I have directx 11.

    First thing to do would be to check the compatibility of the individual games that you are trying to play the Windows 7 Compatibility Center.

    Here is the link:

    https://www.Microsoft.com/Windows/compatibility/Windows-7/en-us/default.aspx

    Then, DO NOT ever update the drivers through Windows Update. Always install the drivers from the manufacturer's website.

    Is your Windows 7 install an upgrade of Windows Vista?

    Titanic, travel, etc. - are these games, bigfish, BTW?

    If so, contact them.

    I feel ultimately that your user account may have got corrupted somehow.

    Create a new user account and check if you can play the games there.

    If so, fix the damaged user account.

  • Flicker flashing white screen...

    My computor screen starts to flicker, flash, then the screen turns white and the computor freezes while remaining on. Does any program I am running, music, internet, word etc... Any ideas?

    This is a portable computer or a computer?

    If the computer screen is blank how do you know that the computer froze?

    If it's a computer you can try another screen see if you get the same problem. If it is a test of the laptop an external monitor and see what happens.

    If it's a computer. There may be value to unplug monitor and resecuring cables and also re-seats of the graphics card (if it has separated).

    If it's a laptop - when it is empty... If you look very carefully or shine a bright light on this subject from a perspective you see the picture?

  • Qosmio F30 doesn't work anymore - white screen

    Good evening.

    I seriously need help with a problem with my qosmio F30.
    For some unforeseen reason, he decided to stop working and I am struggling to think of any reason why.

    He is able to enter the laptop itself and when you press the power button the surrounding blue light also, however, that's all, that's all that happens. The cooling fan comes after 30 seconds as planned, but the lights on the front do not indicate the hard drive, kicking in, or actually the any lights on the front, other than the power.

    All I get is a blank black screen. I use my neighbors pc right now which is annoying and I could seriously do with a Board of experts on ho to fix this problem because it is now out of its warranty

    Kind regards

    Hello!

    Just a simple question: you see an image on the monitor of extenral? I ask this question because theoretically the internal monitor may be defective.

    If the outside monitor doesn t work too I think that it s that a hardware malfunction and you should go to an authorized service provider. Technicians can check the laptop's motherboard or the CPU may be defective.
    Here, you can search an ASP:

    Hello

    As far as I know, Toshiba does not support and does not all drivers vista for Qosmio G, G, F10, F20.
    The Vista drivers are available for G Qosmio F30 laptop
    Therefore, you will not be able to find common modules and others on the download site Tosh.

    The needs of Vista and wastes many resources of the laptop! File, the picture transparency and the Aero feature needs min on 256 MB graphic card, fast CPU and min 1024 MB of memory.
    Here are the requirements material min!

    But you should also check if the transparency of Vista (Eye Candy, magnifying glass effect) has been activated!
    To enable or disable this effect do this:

    1. right click on an empty area of the desktop
    2. Select Customize from the context menu
    3. click on window color and appearance Option
    4. check if you want to enable transparency or not.

  • Qosmio F10-124: can I upgrade my CPU a faster chip?

    Can someone tell me if I can improve my CPU to a faster chip, I have the 1.6Ghz CPU in the moment, but I don't know if this is a plug in type or if it is soldered on the motherboard.

    I called Toshiba and they were asked, but until I'm practically the question out, he said no, can anyone help?.

    Thank you very much, Pete.

    Hello

    Generally it is not possible to upgrade the CPU because of several reasons.
    But as far as I know that different Qosmio F20 models were shipped with these processors:
    Intel Pentium - M 1.60/1.73/1.86/2.00/2.13GHz
    Intel Celeron - M 1.40/1.50GHz

    My laptop is dead! If anyone had the same experience or knows what could be the problem please help!

    Thank you!

    Hello

    It looks like a hardware problem!
    I think it s a GPU (graphics card) malfunction.

    What to say that the replacement is not easy and I'm sure just a portable computer user cannot solve this problem without any other help from the technician.

    I really recommend to contact the service provider authorized in your country.
    Explain all the details guys and I hope that the ASP finds a quick fix

  • Qosmio F10-124 - Question on WIN XP / Recovery of product

    Hello world!

    I tried to use my product recovery DVD-ROM. The display at the outset that it is for 'Win 98'. I predicted, he should have read Win XP. Needless to say that I do not go any further. I guess that Windows Media Center is contained in a product recovery disc. ?
    Where is the center of the media to the folders/files in my notebook?

    Thank you
    Hill82.

    Hello

    Please don t look at what is stated there, just use it. The recovery DVDs has been tested and it will work. Be careful about installing, you'll do. There are standard and expert modes.

    Standard mode will remove all HARD drive and install the OS. Using the expert mode, you can create a partition or install OS on already created one and the entire contents of the HARD drive will not be deleted.

  • Start-up and white screen issue after updating to v10.11.5?

    I can't say 100% that my problems are related to the last update, but I thought I'd ask.

    I've updated about 4 or 5 days ago, and although the questions did not begin immediately, they start after the update. It should be noted that I have never had issues like this before.

    Here are some of my questions on my MacBook Pro (17 inch, early 2011), 2.2 GHz Intel Core i7, 8 GB at 1333 MHz DDR3, Intel HD 3000 512 MB graphics card

    1. the monitor will sometimes go haywire and a strange split, screen where the mouse can go to the left side of the screen and reappear on the right side of the screen, because the office is now split into two

    2. computer crashes and the monitor starts flashing to show a blue zigzag striped background

    3 freeze during startup and never restart computer. Occasionally, it will start very well, but the computer locks upwards at some point while using

    4 computer at boot flashing out to a white screen then restart never

    Thanks for any help.

    Now I'm starting to think my problems are related to a single user, sign in. Only 2 people use the computer and my connection seems to be fine. No crashes or anything like that.

    The problems start when my wife logs in to his user account.

    Thought I would mention it.

    Any help/response would be appreciated.

  • White screen after the upgrade, thoughts?

    Hello

    I have a mid-2011, 21.5 "iMac. When I upgraded from Yosemite to El Capitan, I got the white screen of death on restart. I saved time machine, reinstalled, and everything was fine. When I did the update niveau.1, the same has happened (white screen, then backup, and then reinstall) and now, last night, after le.2 upgraded the same story happened.

    When I run on the armored white mac disk utility, it shows all the hard drive as being full of the 'other', which is certainly not, but the drive is labeled as OK.

    Before I try reinstall, I want to know: what am I doing wrong? I'm upgrading via the App Store, I don't have a hackintosh, no illegal absurdity, etc.. But this problem is boring and repetitive, so I figure there must be something I do. Any thoughts?

    I got a grey screen for a few minutes, I came back a little later and I was looking at a login screen.

    The whole process has been about half an hour.
