renamed authui.dll and get black screen

Hi, last night I tried to make a customization of my computer, browsing the internet I found a bootlogon authui.dll from a trusted site. After taking possession of the original file and rename it to authui.dll.backup I could not make any change or copy a new to the system 32 folder. Once I restarted my pc to try to fix it by going into safe mode but the back is going in any mode the vista loading bar appears but then I get a black screen with the cursor and I don't get logons or whatever it is, keep it just like that. so is it possible to fix this or get a window command prompt in the start menu so I can rename my file in normal.i will be really grateful for your response. Sorry for my English

Hello

Have you tried selecting mode safe mode with command prompt from the start menu? Otherwise, you could try to load the Recovery Console by starting with your Vista disc. (If you do not, see:http://neosmart.net/blog/2008/windows-vista-recovery-disc-download/). From there a system restore can also be a solution.

  • Repair installation fails on Windows 7 and get black screen

    I put in a repair disc and then I put in a disk to reboot and did he pulled upwards so that I had to do a reboot but got black screen saying something was not so tempted excessible to esc but used left me tried to restart again and it will not restart please help running windows7 64 bit

    This is usually caused by hardware or software that is not compatible with Windows 7. If you have this problem, follow these steps:

    Wait about 10 minutes to see if the installation continues. Look at the led on the hard drive (often a small light on your computer that blinks when your hard drive is running) to see if there is no activity. If your hard drive seems to be working, the installation must be current. If your hard disk doesn't seem to work, go to step 2.

    Uninstall all antivirus software, and then restart your computer. Don't forget to enable antivirus software after you install Windows.

    If the installation fails again, it may be a hardware incompatibility problem. Go to the Windows 7 Upgrade Advisor on the Microsoft website to see if your computer can run Windows 7.

    If you have compatible hardware and your computer still stops responding, disable any unnecessary material. Remove (USB) universal serial bus devices. Remove or disable network cards, sound cards and cards of the series; and then restart the installation.

  • HP t510 and t5565z black screen

    Hello

    I have several HP t510 and t5565z thin using HP Smart Client OS we use for VMware View customers. Thin clients for very well most of the time. However occasionally they will get black screens and no longer respond. I would say that this probably occurs during long periods of inactivity may be several hours or more. Has anyone already experienced this? It can occur during a session connected or simply sitting lit all night.

    These thin clients also seem to have a kind of construction in both screen saver. Because they will go in this black screen after 15 minutes of inactivity. They return generally, but I can't find anywhere in the settings options or BIOS to kill this screensaver.

    To anyone reading this, I found a solution. I found myself by opening a ticket with HP about the sleep function screen integrated with Smart Zero Client generation. I was information this feature was not available without the component of profile manager of the HP Server deployment, you can use this thin client.

    I finished the switch back on the ThinPro build because you can control the screen saver and display the power options in the generation of HP. I had a feature request to HP to allow the screen saver and power display options to be greeted with the Smart customer zero built in the future because they added an Admin mode in the last generation, they pulled out for us who do not have enough of them to justify the use of the server component.

  • Satellite L300-1AP and Win8 - black screen on startup

    Hello

    My computer starts as usual, the first screens come well and it will also in the journal of the user on the fine screen.

    However when he was usually in the Windows 8 home screen it goes just a black screen.

    The mouse icon is still there and the work, but the only thing that I can get up is the Task Manager.

    No idea what it is? Eventually a failure of a Windows 8 pilot as everything else seems to work?

    Thank you!

    I agree with Timox; It would be interesting to know if the laptop is working correctly by using another system; in the best case with the system pre-installed and pre-configured by Toshiba or Windows 7.

    I m interested also in the installation procedure you install Win8? Did move you from Win 7 to 8 Win or did you do a fresh install?

  • Upgrade and repair black screen CQ61

    Hello

    I have a laptop Presario CQ61-214TU.  Upgrading to Windows 7 from Vista.

    Push the power button, I get a black screen and the fans and leds of power.  No MESSAGE or BIOS.  The LED caps lock flashes very slowly 3 times and then the unit resets.  When she comes back, it's the same thing the fan on, black screen except the CAPS LOCK led flashes slowly and continuously.

    I tried to disconnect the battery and AC and hold the power button / stop and most other Councils (removal of material, etc.) on the websites and the service.  (except those overheating).

    I guess that the motherboard or processor are defective.

    The mobo is 578053-001.

    The processor is AM80577T4300.

    As I have these out, I thought I would upgrade one or both.   What is the combination of both that I can put in the CQ61-214TU on an empty stomach.

    Thank you

    Here is the Manual:

    Manual

    The motherboard list you does not appear in the manual, or is the processor, although the official HP specs also show that you have the Pentium Dual Core T4300 processor and this motherboard withdraws as a motherboard Intel CQ61. Fastest compatible processor is listed as a P8700 2.53 GHz.

    This is a replacement for your motherboard:

    Your laptop has nVidia graphics and is as good as it gets in this series of laptops, which is not a high end machine. So if you get the P8700 and a duplicate of your Board, you'll have the max hardware you can get. I have a question putting almost $200 in it, but it's your call.

  • monitor gets black screen

    My monitor guard rethink a black screen when I turn on my computer, basically when I turn it on I see start for half a second, then I get the black screen while my monitor is always on

    Now, I recently built a computer, put it a few days ago the same thing happens, I didn't install anything don't not even windows 7 yet, but when I turn on the computer I get the black screen again, I can not install windows

    My brother and his friend think it is the graphics card, but when I built my new computer black screen continued to occur. If I turn my screen I can see my screen for half a second, and then it just goes black again.

    Yes I checked the cables for the monitor, I have even plugged into my laptop, and the same thing happened to the monitor

    So I was wondering... What is the cause of the problem? my brother think that theres something wrong with the new parts, I think it's the monitor that is causing the black screen and I have to buy another... What is it?

    Hello

    Since the monitor displays the same black screen after connecting to a laptop, this might be a problem with the monitor. Contact the manufacturer of the monitor on this issue.

  • Just get black screen on Acer Aspire 7520

    I'm looking for a solution for this problem for almost 3 months now. My Aspire 7520 when tuned to just gives me a black screen. I took out the battery and held the power button down / stop and always the same. I also made sure that the fan has been free of dust and is runnig and I hear that it is trying to load, and now when I turn it off it is itself so I have to remove the battery all together.

    If you get either of the image on an external monitor, it could very well be a video card problem or a problem with the motherboard.  You should contact your local service centre Acer for assistance.

    No saving necessary data and re-installing Windows Vista might be the best option, but here
    are a few others.

    You can save your files by putting the drive in another computer as a 2nd disk (best) or external
    Drive USB enclosure and then backup to removable media such as CD, DVD or other USB drives.
    Of course a real store of the computer or the manufacturer of your system can help to recover the files.

    Or you can use a boot Ubuntu CD to back up data.

    Black screen problems are extremely difficult to repair and all hotfix is usually a hit or miss
    base. That there is no information on a black screen as there is just a blue screen
    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 of efforts.
