White screen when I power on the computer

I have Windows Vista. It began Monday, today is Thursday. I turn on computer tower as usual. Screen remains blank. tried turning off, would not turn off. (I know now from my neighbor to keep in touch during this problem) so I unplug a minute. all that happens is screen Black w/white letters saying: "windows has not start blah, blah, before we get to the end of reading, it comes down to, 'windows is loading file'. '. If I leave it alone for a while, only he's stuck in this mode. I turn off, then on. Finally, it loads windows. every day this same week thing. Today, it took almost an hour to power off before loading Windows. I only had a few months to this computer. I deleted the browser and when it was loading also did a system restore thing. Must I do and is it safe to make a PC Cleaner? AND what if I turn it off at night?

Turn on your pc and immediately start pressing F8 (before the windows logo)

Select Safe Mode and wait for it to load
Then logon as the administrator account, if you have assigned a password, type it in, otherwise leave blank.
Then click the Start Menu > then click run
Then type cmd and press OK.
Then type sfc/scannow , and then press enter
He'll then fix system files automatically
Then type chkdsk c: /f and press enter
When it asks if you want to run the check disk the next time it boots, type o and press on Enter.

The steps above will fix the missing or damaged files, and the disk check will scan the hard drive for problems in the partition automatically for you. That should do it.

  • White screen when I turn on the Satellite M50

    I have intermittently just get a white screen when I turn on the computer. Usually, the problem is solved by turning off the computer and try again - but sometimes I get a white screen again.

    It seems to be linked to the use of external devices - can someone give me clear instructions on which expected/doesn't have to be connected when I start and shut down the computer? Or other suggested solutions?

    Thank you

    Hi Rachel

    Believe me; It's not easy to provide an exact solution and that's why we need to study a little ;)

    Have you checked if the graphics card driver update could solve the white screen issue?
    If not, try to download and install the latest graphics driver

    You second question on the laptop stop problems is known to me. Sometimes it happens on my laptop too. The LTCC is a part of the Norton antivirus application, which is still running in the background of the operating system.
    This strange box "close the program" might appear because this context process couldn t be closed automatically and so the operating system can not stop.

    Especially the new application installation might help you. But why don't you use Norton Antivirus? What makes the laptop very slow. I have used this app for a long time but now I use the freeware program called Antivir. Its free and in my opinion much better than the Norton Antivirus.

    Hello

    Chances are the hard drive failed, but it could be wiring or other materials.

    Check with the system manufacturer's support, their documentation online and ask in their forums
    (if any). Most have instructions to replace the hard drive.

    You can usually buy a hard drive for alternatives for less than $100,00 and maybe much less. Or the other
    get the same one or the same size.  System manufacturers usually several models if you
    the same can buy cheaper. And there will be others who are of the same size and type which
    can be used. Your local computer store can help select an appropriate player.

    Here is an example of how to replace the hard drive on some HP computers for example. Most
    other manufacturers are similar, and there are many generic examples on the internet.

  • Alienware x 51 r3 crashed to the Alienware logo screen when I turn on my computer first time every day.

    My new r3 Alienware x 51 will not start windows when I turn the first time on the computer in daily life.
    When the Alienware logo is displayed on the screen, the computer will not load. (No loading cycle appears under the alienware logo). Then the screen becomes black. Keyboard and mouse lights are turned off. Some time, the screen becomes blue background of windows, then the loading cycle does not work any time more and some, the screen has crashed on the Welcome screen of win 10. However, when I turn off the computer and start again immediately. It works normally. If I switech it off and then start it about 2 hours later, the computer will crash again. Every day the first time to activate it, I have to run it twice.

    I used Dell diagnostic software to search the computer, everything is OK. But it's my second X R3 51 during this period of a month. The last graphics card problem, I switched to this one. But the other also has the same problem. Therefore, in my view, it is that my other hardware problem? I connect a keboard Corsair K95 RGB, G502 mouse, joystick Thrustmaster and a saitek rudder. I used a USB 1 4 adapter to connect some of them. The X 51 system is widows 10. I've also used these materials with a X 51 R2 two years previous. Never encounter this problem.

    Got my X R3 51 in December. All of us have had this problem of gel. I "think" what fixed my X 51 R3 rose dating drivers for Intel hardware. Download and run Iobit Drive Booster or snail Majorgeeks.com driver and see if it helps.

    ATTENTION:

    If you use Iobit Drive Booster, uncheck download AdvancedSystem care before installing the Booster Drive. AdvanceSystem Care blocks every time my hard drive.

    I use the first Elements 9 software.  When I add clips to the timeline and press play, the video does not play in the playback screen, instead I just get a white screen.  Once I hit the pause button, the image of the chassis on the playerhead is back on the screeen, but as soon as I hit the play button, the screen becomes white again.  I've updated my graphics card drivers and project settings are correct.  What is causeing the question?

    That's what I get when I hit the play button:

    Yes, this driver (I plugged it in Win7-32 bit OS), is the last one (296.10 WHQL) shown on the nVidia website.

    I open the console from nVidia and see if there is a parameter, which may interfere with its performance. Look for things like 3D, stereo-Vision acceleration, etc.
