My computer will turn on - the windows bar shows and then the screen turns black. How can I fix this problem. I had early erased some programs from my computer but I didn't think that this should cause any problems.

    When the bar comes on the screen, this means the kernal for Windows Operating is loading. If it completes and than hangs the problem is in the Ini files and/or registry. This could be caused by anything from a bad registry entry to a bad or inproper driver load. If you just updated a driver such as a video or sound driver. If you just added new software the problem can happen. If you removed a device and it's driver the problem can occur. A trogan Virus can do this. So, as you see it's hard to resolve this issue without more info. Try to Boot in Safe Mode using the F8 or F5 key just before the bar starts, a screen will ask you how to boot. Select safe mode. If the machine does boot to the desktop, your problem is now usually a driver problem. A Trogan could still be loading into memory before Windows boots and cause the issue though. This is all the help I can offer at this time without more exact info and history.

If you leave the computer it will eventually boot up, but something is causing the delay. Why not try booting in safe mode by pressing F8 as it boots and restore it to an earlier time when you know everything was working okay. Sometimes when programs are uninstalled they can take files that other programs rely on. Try restoring by pressing F8 on boot entering safe mode, go to start>programs>accessories>system tool>system restore and choose a date when you know that the computer was working okay with no problems.

I hope this helps

You have to install another operating system
Restart your computer during the boot process you will see on the screen to press a certain key to enter setup usually the Delete or F2 key

Press and hold that key during the boot up process to enter BIOS then using the arrow keys scroll down to advanced bios features press enter change your first boot device to cd press escape then press f10 to save to cmos to restart

Note this will erase you operating system you will have to have an operating system disk to load it onto you hard drive or create a partition to load another operating system

Note after you have loaded the operating system you should go back and change the first boot device to failsafe or optimised defaults after windows has loaded

your computer will automatically restart it might restart 2 times one to finish the installation
the next will be because the operating system is loaded and will boot from your cd

or
Formatting a hard drive to erase its contents does not mean the files are necessarily gone forever. Using data-recovery software, someone still could retrieve sensitive data and files from your hard drive even after you've formatted it. Instead of simply formatting your hard drive, use disc-cleaning software to permanently erase its contents. Disc-cleaning programs work by repeatedly overwriting the contents of a hard drive with random data patterns, making it virtually impossible to recover the original files. Download and install the freeware program Active@ KillDisk (see Below). http://www.killdisk.com/downloadfree.htm Click the Windows "Start" button and select KillDisk from the "All Programs" list. Click the check box next to the hard drive you want to erase in the "System Local Disks" menu. Press the "Kill" button. Select the erasing method you want to use from the "Erase Method" drop-down menu. Active@ recommends using the "US DoD 5220.22-M" method. Click "Start" to begin erasing the hard drive. Download and install the freeware program Hard Drive Eraser (see Below). http://www.harddriveeraser.org/ Click the Windows "Start" button and select Hard Drive Eraser from the "All Programs" list. Check the radio button next to the hard drive you want to erase under "Select Drive to Erase." Select the erasing method you want to use from the "Shredding Scheme" drop-down menu. The developers of Hard Drive Eraser recommend "DoD 5220-22 M" Press the "Start" button to begin erasing the hard drive. Download and install Iolo DriverScrubber (see Below). Click the "Windows" Start button, "All http://www.iolo.com/ds/3/ Programs" and then the DriverScrubber program icon. Click "Wipe all contents of a drive," and then click "3.5-Inch Floppy Disk." Insert a blank floppy disk and click "Next." Restart your computer with the floppy disk still inserted. Your computer will boot directly to DriveScrubber. Press the down arrow on your keyboard to highlight the hard drive you want to format in the "Available Physical Drives" menu. Press the space bar to select the hard drive. Press "Enter" to continue. Press the down arrow to highlight "Seven Overwrites" in the "Available Data Wiping Methods" menu, and then press the space bar to select it. Press "Enter" to continue. Press "CTRL," "ALT," "Shift" and "W" at the same time to wipe the hard drive. Hope this helps.

E640 REBOOT


Hi John,

I see you mentioned you update IE9 then you now get a blank screen...

If I may ask the blank screen showed up after the update or did it show up after restarting the computer?

If your getting a Blank screen when you boot into windows after the IE9 update, try rebooting then boot into Safemode.

Restart you computer then as soon as you see the Boot screen of you computer keep on Tapping f8 to get a list select safemode, then once it boots into safemode windows will load up in safemode on the issue and you can navigate arround to fix things that went wrong.

click on the Start Button on the lower left of the task bar then, click on Programs, select accessories then select system tools, look for system restore then select the option select a different restore point, on the window you may see a list of restore points hoping your system restore was turned on in the very beginning, once you have selected a restore point keep on clicking next then a warning will show just click next again then it will restart your computer.

System restore allows you to restore to a date where you had windows working fine without any problems so if you can get a restore point before updating IE9 then it is possible that you may be able to fix you windows back the way it was.

I hope that this will help,

The computer has a black screen with just the mouse cursor. no buttons on keyboard work and it wont turn off


Generally when this happens it is because Explorer.exe has crashed, thats the program responsible for your start menu/task bar. You can press ctrl-alt-delete at the same time and click task manager and tell it to start a new program 'explorer.exe' sometimes this will fix the issue, but if its happening when the computer is first turned on it most likely will not. The other option is to press f-8 repeatedly as the system boots up and you will be shown a menu, one of the options of which is 'boot into safe mode' now if you boot into safe mode fine with a start menu and everything, then the next step is to click start, then in the search bar type "msconfig" one of the tabs will be called startup. This is a list of all the programs that are being run when you first turn your computer on , one of these programs is most likely causing the problem, you can simply remove all of them to start with just to see if it fixes the problem, then go back and add any that you would like to have running on windows boot.

I'm trying to change the screen resolution while running windows 7 because I have no desktop showing on my monitor


Firstly, there appears to be many causes of the black screen issue. The symptoms are very distinctive and troublesome. After starting your Windows 7, Vista, XP, NT, W2K, W2K3 or W2K8 PC or server the system appears normal. However, after logging on there is no desktop, task bar, system tray or side bar. Instead you are left with a totally black screen and a single My Computer Explorer window. Even this window might be minimized making it hard to see.
If you have these symptoms you can safely try our free Black Screen Fix. It will fix the most common cause we have seen of this issue. Running the fix program is easy under normal circumstances, simply download with your browser using the link above and run the program. However, if you are trying to do this from the PC which has the black screen it is a bit more tricky. In these circumstances follow the procedure below: 1) Restart your PC 2) Logon and wait for the black screen to appear 3) Make sure your PC should be able to connect to the internet (black screen does not appear to affect this) 4) Press the CTRL, ALT and DEL keys simultaneously 5) When prompted, Click Start Task Manager 6) In Task Manager Click on the Application Tab 7) Next Click New Task 8) Now enter the command: "C:\Program Files\Internet Explorer\iexplore.exe" "http://info.prevx.com/download.asp?GRAB=BLACKSCREENFIX" Note this command assumes that you are using internet explorer as your browser, if not substitute your browser path and file details for those of iexplore.exe or use the Browser option of Task manager to locate it. 9) Click OK and your browser should start up and begin the download process 10) When prompted for the download Click run, the black screen fix program will download and run to automatically fix the issue. 11) Now restart your PC and the black screen problem will hopefully be gone.
