Window can't log on?? when notebook on window logo display after few second computer is restart....any solution???

sounds like a virus!

1. Remove all floppy disks, CDs, and DVDs from your computer, and then restart your computer.Click the Start button , click the arrow next to the Shut Down button , and then click Restart.
2. Do one of the following:
   
   • If your computer has a single operating system installed, press and hold the F8 key as your computer restarts. You need to keep tapping on F8 before the Windows logo appears. If the Windows logo appears, you'll need to try again by waiting until the Windows logon prompt appears, and then shutting down and restarting your computer.
   • If your computer has more than one operating system, use the arrow keys to highlight the operating system you want to start in safe mode, and then press F8.
3. On the Advanced Boot Options screen, use the arrow keys to highlight the safe mode with networking
4. download malwarebytes http://www.majorgeeks.com/mg/getmirror/malwarebytes_anti_malware,1.html#.U2QUMfldU41 it a safe place to download it from
5. install and run

Hi,

First try to check if you can log to your computer via Safe Mode, if you can then there is a few possible things happened to your computer:
1. Corrupted software installation that is messing up with your startup services.
2. Hardware problem (memory or bad sector in the hard disk)
3. Or Operating system or malware.

Anyway for the step to test if you can log in via Safe mode try the steps below:
Reference: Safemode
Open Safe Mode with the F8 key

All Windows versions can be booted into Safe Mode by this method. Note that it is somewhat tricky to time this procedure and it may take several attempts.

1. Turn on or restart your computer.
2. Hold down the F8 key before the Windows logo appears. If the computer makes a complaining noise, tap the F8 key repeatedly instead of holding it down.
3. If a Windows logo or "Windows starting" appears, wait until Windows loads. Then restart the computer and try pressing F8 again.
4. Once you are successful, a menu will appear with a number of boot options. Use an arrow key to navigate to "Safe Mode" and press the Enter key.

Trying to get to Safe Mode by using the F8 key can be frustrating and there is another way that uses the System Configuration Utility (msconfig).

You may want to check your dispaly properties to make sure that your display is set to HDMI instead of laptop display in the control panel under display properties. On many laptops, this can be done by pressing the "fn" key and a key with a blue symbol of two screens on it. This toggles between your primary display and external ones.

Try a System Restore and select a restore date before your problems started.
To get to the System Restore - Click on Start - All Programs - Accessories - System Tools - System Restore

had a similar problem over the last couple of weeks which culminated in the Blue Screen of ***** and hard drive FAIL. Cost 120 euros to replace on a Hewlett Packard laptop. Sorry. :(

Power off the computer, then restart it. As soon as you see the eMachines logo appear on the monitor screen, press the "left-Alt" and "F10" keys simultaneously. Wait a few seconds for the Windows boot screen to appear, then press the "Enter" key.

Click the "Restore Operating System to Factory Defaults" option after the eRecovery Management window appears. In the Notice window, read the warning that states all information on the drive will be lost, then click the "Next" button.

Click "Next" in the Restore Destination window, then click "OK" in the final confirmation window. The eRecovery Management utility formats your main system drive and reinstalls the original software that shipped with your computer. A progress bar notifies of you of the current progress of the recovery. The recovery utility may prompt you to restart your computer several times during the recovery process. Restart the computer when prompted. The computer reboots automatically after the recovery finishes and launches the Windows First Time Setup. The recovery takes between 10 minutes and one hour depending on which model eMachines computer you own.

Follow the onscreen prompts to customize and personalize the Windows installation on your eMachines computer. Log in to Windows with the username and password you choose during Windows Setup.

Please restart the computer and go to safe mode by tapping F8 key once the system is restarting choose Enable VGA Mode (Windows XP)
choose Enable low resolution Video (Windows Vsita / 7).

Change the display settings to slightly lesser than what the monitor can handle and shut down and restart the computer in normal mode.

Very doubtful. Either you have a defective or corrupt display driver, or possibly a malware infection. Is that a laptop or notebook computer? If so, is there a VGA port for an external monitor? If do, try using a known good external monitor.

Try uninstalling the display driver from the Device Manager then restart the Computer. After restarting the Computer, reinstall the display driver.

Perform the steps given below to access the Device Manager:
(i) Please press the Windows logo on the Keyboard and then press the "R" key while holding down the Windows logo key to open the Run dialog box.

(ii) Then, please type "devmgmt.msc" in the Run dialog box and click OK to open the Device Manager window.

(iii) Click on the plus sign next to the "Display Adaptor" category to locate the display adaptor.

(iv) Right click on the display driver then click Uninstall.

You can download the display driver from the support site of the Computer manufacturer.

When starting the computer tap the F8 key repeatedly. The Windows Advanced Options Menu appears. If you begin tapping the F8 key too soon, some computers display a "keyboard error" message. To resolve this, restart the computer and try again. Ensure that the Safe mode option is selected. Press Enter. The computer then begins to start in Safe mode. When you are finished with all troubleshooting, close all programs and restart the computer as you normally would. Or you could do a system restore to a earlier date when your computer was working fine.
