COMPUTER IS IN MARKET, BUT MY SCREEN IS EMPTY AND CANNOT ACCESS ANYTHING WHATSOEVER

My laptop HP Pavillion dvr-1200 CTO has a huge problem. It will not display anything other than a model fixed rotation of blocks of colors - it goes from red to blue, to green for a sort of wih shadow grey verticle lines, each for about ten Secord, repeating again and again. You can hear the computer start-up, and you can get to the start page to know when to press enter and when to scan fingerprints; It comes as I can get without seeing. I had the problem for about two months; misfortune is after a week or so, I decided to plug in an external monitor to it and got a complete table, with everything except the display works fine. Unfortunately, hastily excited, I decided to be a graphics driver issue, which would mean simply an update or a new set of drivers. Large. But I accidentally deleted the drivers that I had until I downloaded the new, and the extrnal screen I used erased. Now, I have no idea what to do! Any suggestions...?

Hello, @postalbbouy

Welcome to the HP Forums.

I see you had a problem with the display of laptops, which had bypassed you it with an external. In trying to fix the laptop you removed the graphics driver and have now no poster.

I want to help you with this. However, with the description of the screen of the laptop looks like you will need to replace. Ways to get the graphics driver, all require a form any Visual to do.

I recommend you contact the HP support by phone to see what repair or replacement options are available.

Please contact our technical support at the 800-474-6836. If you do not live in the United States / Canada region, please click the link below to get help from your region number. http://WWW8.HP.com/us/en/contact-HP/WW-phone-assist.html

  • Re: TV TOSHIBA 26EL800A - TV is on, but the screen remains empty

    Hi all

    I have a Toshiba TV 26EL800A purchased in May of this year. Tried to turn on the TV using the remote control mode standby (red light) to on (green light) that has the remote control - the screen remains empty (as there is no power) and after a few seconds the light changes again red - standby again.

    Tried this using the keys on the TV as well and the same thing (have checked batteries for remote control, checked PowerPoint (my dvd player works the same record 2 and it works) but don't know what else is causing the screen lights?)

    Any suggestions?

    I put t really know if you can find the solution here on the computer systems forum.
    What you can try is to unplug TV, leave for a while and check again.

    If the same thing will happen again and again I recommend to contact your local dealer and ask for help or contact the provider of Toshiba directly.

  • SE error message: "nvlddmkm.sys not answer but recovered" and cannot access Starcraft II or LOTRO

    Original title: nvlddmkm.sys does not

    Just started having this couple weeks message. Killed or damaged at least one of my 9800 GT cards (SLI), which have been replaced under warranty. Who sets the part of the question of the display, but still cannot access to Starcraft II or LOTRO - connect and just get a black screen (have sound, no picture). Then the message "nvlddmkm.sys not answer but recovered" then nothing and having to use task Mgr to close the program. Here's the suspect: update the video driver (uninstalled old, clean install) which again helped a little but the screen remains black when entering the games. While they inspected the files, the file Nvidia\Displaydriver shows the new driver as the device Mgr when I check that. BUT then when I check the directory ofC:\windows\system32\drivers there is still an OLD version of nvlddmkm.sys. I'm sure that it is the culprit, but it won't let me delete it or rename it who were other corrections that I read about. I know that this is an endemic problem with Windows and has been for awhile now. ANY suggestions?

    Hi malomar,.

    1. This only happens when you play Starcraft II and LOTRO?

    You can try to uninstall and reinstall all the programs and features Nvidia drivers and Device Manager.

    Step 1:

    Uninstall the audio drivers from programs and features

    a. click on start

    b. type appwiz.cpl in the start search

    c. search for all driver packages, Nvidia, right click and uninstall.

    Step 2:

    Uninstall the drivers from Device Manager.

    a. click on start

    b. type devmgmt.msc in search, and then press enter

    c. in find Manager device for the device, right-click on it and select the option uninstall.

    After you remove the drivers of these two places, you can try to remove the NVIDIA folder and restart to see if that solves the problem after I installed the generic drivers.

    Step 3:

    To delete the folder:

    one. Click on start and Type C:\windows\system32\drivers folder in start search

    b. click on drivers and select nvlddmkm.sys

    c. right click and rename nvlddmkm.sys in nvlddmkm.sys.old. or delete.

    d. restart the computer and check.

    You can also check the manufacturer's website and download the latest drivers from Nvidia:

    http://www.nvidia.com/download/index.aspx?lang=en-us

    Also check the Nvidia support link:

  • Starsiege Tribes - screen is small and cannot click

    I have a game called Starsiege tribes which came out in 1996 that I tried to play on vista with all service packs and now the new Windows 7. Even the compatibility program could not operate on the old settings. I remember playing on XP and same 98 / me.  The problem is this: the loading of the game through the sequence from the beginning to the menu page when the mouse is ineffective. I can't click on anything, but the keyboard seems to be working. In addition, the display settings are all off. The screen is small and the Windows menu bar does not disappear as it normally does when loading a game.  That and the bar of the window at the top that doesn't go away also. Any help would be great!

    Try this place.  It is tribes with practically every necessary to play, including a Vista patch update.

    Hello

    Setup of full software functionality for Windows 7 is on the link below - download this and save it to your desktop.
