Area 51 ALX video goes black once the machine is warming up

My second question concerns the reason why this computer was good for me.

When I first start the computer, it seems to work, but once video cards warm up (and they get really hot) video signal to cancel completely.  There is nothing to come to one of the DVI (there are 4 of them on the back of this machine, 3 active).  It will start working again after a hard reboot, but the signal is not always go to the port that I had been attached to.  In other words, I had to run after the video signal around the ports.  I also changed the power settings to prevent it from "sleep" for a long time, but this does not seem to have made all the difference.

I updated the bios to A10 and run several diagnostics show that the system works perfectly.  The system does not respond to the keyboard, but I don't know if it is really "locked" because I networked hard drive of ALX and was able to access a computer on my network even though the screen was black.  I copied things from him and him very well and if he is really blocked, he would not have answered at all, no?

If this sounds like something you treated, please let me know.  I have a few ideas to try this holiday weekend, but I'm open to other suggestions.  Thank you!

I suggest that you clean and check all fans (including those on video cards) and the radiator. Yes, video cards running more hot than the CPU, but they shouldn't be hot right on the Windows desktop.

Reposition the graphics cards, ram DIMM, all connectors power supply.

Test until do you fail, then troubleshoot

    I tried restoring the system that works and that gets our screen back to normal but every day that this Auto setting is coming and we can't seem to stop it.

    Try this:

    Go to the Web site of the manufacturer of your laptop computer-graphics/computer card > drivers and downloads Section > key in your model number > look for the latest Vista drivers > download/install them.

    Then:

    http://Windows.Microsoft.com/en-AU/Windows-Vista/change-screen-resolution

    Change the screen resolution

    Screen resolution refers to the clarity of the text and images on your screen. At higher resolutions, items appear sharper. They appear also smaller, so more items adapted to the screen. At lower resolutions, fewer items adapted to the screen, but they are larger and easier to see. At very low resolutions, however, images may have serrated edges.

    Hello

    You can access Mode safe? Repeatedly press F8 as you start? If yes you can try Control Panel - device
    Manager - graphics card - Double click on - driver tab - click on UPDATE driver - then right click
    on devices and UNINSTALL - REBOOT.

    Another method to try to get to the desktop (try in normal Windows Mode without failure)
    CTRL + ALT + DELETE and on the tab process EXPLORER.exe and COMPLETE the PROCESS on this subject - then
    on the Applications tab - lower right - new task - type in EXPLORER.exe. Safe mode is reached
    by tapping F8 as you start several times.

    Black screen problems are extremely difficult to repair and all patch is usually on a base hit or miss.
    That there is no information on a black screen as it is on a blue screen just adds to the
    Difficulty. Often using a restore point or Startup Repair will have no effect. You can try a
    Google to see the proposed repairs, whom some have worked however these cover a wide
    field efforts.

    Here's a video of one of them.

  • Screen goes black when the unit reaches a point in 3d space.

    Hello

    I've simplified a more complicated model to try to understand what is happening, but I can't for the life of understand me. My camera starts to zoom in to a way of 3d layer in the distance. Everything's fine until it reaches a certain point, then the screen goes black. The camera did not run in the layer, I don't think that the lights have something to do with it. It just goes black. Any ideas?

    The first image is when the camera starts panning. The second is when the screen goes black. Note that the camera is still quite a distance between the 3d layer.

    Screen Shot 2011-12-01 at 12.46.04 AM.pngScreen Shot 2011-12-01 at 12.46.28 AM.png

    Thank you!

    If you turn on diagrams, you'll see that your camera is not pointed at the level of the layers. I don't know why you have animation camera rotation. You have the camera facing the path, is the point of interest to market? You may experience gimball lock.

    The best way to animate a camera must do 3D null parent. Now you have a camera on a cart. Gimbal lock is not a problem, point of interest is not a problem, and it's easy.

    If your hard drive has failed, so that your files may have already disappeared.

    You can put the drive in an external drive enclosure hard usb or a USB to sata connector allows you to connect the drive hard tro another PC to try to copy the files from the hard drive.

    You can order a usb at HP recovery disk. I can't identify your laptop with the b6b49av that you posted.

    ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

     

    If restore work not and you do not have a Vista DVD from Microsoft, do a repair disc to do a Startup Repair:

    Download the ISO on the link provided and make a record of repair time it starts.

    Go to your Bios/Setup, or the Boot Menu at startup and change the Boot order to make the DVD/CD drive 1st in the boot order, then reboot with the disk in the drive.

    At the startup/power on you should see at the bottom of the screen either F2 or DELETE, go to Setup/Bios or F12 for the Boot Menu.

    When you have changed that, insert the Bootable disk you did in the drive and reboot.
