Samsung all in one pc doesn't shut down


pull the power plug. Reboot and do a repair on the software. You might have a virus or a bad spyware program that has corrupted your OS, if so then do a system restore.

Tip

Reboot and run in safe mode in windows 7,Vista,XP or 2000


Insert the CD then reboot. While the system is booting, hit the F12 key to access the boot menu (this could be a different key depending on your system.
1.) Click the "Start" button from the taskbar. Select the "Turn off computer" option if you are running a Windows OS Operating System before Windows Vista, or select the right arrow in Vista. Select the "Restart" option
2.) Press and hold the Ctrl+Alt+Del keys simultaneously. Do it again. This will reboot the computer
3.) Shut down the computer. Sometimes the computer will not respond to a reboot. Maybe the keys are temporarily disabled or the system has chosen to completely ignore you. In these rare cases, it may be better to shut the computer off using the power button. If you do shut off the computer, press and hold the power button for 3 to 5 seconds. Then be sure to wait a minimum of 45 seconds before turning it back on. This allows the capacitors in the computer time to discharge, which allows the memory (not the hard drive) to do a full dump of data. This allows a cleaner restart when you turn the computer back on.
4.)Disconnect the power cord. Do this as a last resort. Unsaved data may not be retrievable with this option, but sometimes it is the only option. Reconnect the power cord. Turn the computer on. else Insert the CD then reboot. While the system is booting, hit the F12 key to access the boot menu (this could be a different key depending on your system. If you have a problem with your hardware configuration or your computer's display drivers that prevents Windows from loading normally, you may be able to resolve the problem by booting into Safe Mode and changing the relevant settings. To enter Safe Mode in Windows 7, Vista, XP, or 2000:

Note: If you have more than one partition installed, you may need to select an operating system and press Enter before entering Safe Mode.
Turn on or restart your computer.
After the memory test, the words "Starting Windows" will appear on a black background. When this happens, press and hold the F8 key. This will present a screen with the following options to choose from. The exact moment that F8 is pressed will determine the contents of the list, and the list may vary from computer to computer. For example, your computer may not do a memory test or it may have a SCSI BIOS to load in addition to the motherboard's BIOS. If you have trouble getting the list below to appear, restart the computer and then press F8 repeatedly while the computer is starting.
Safe Mode: Boots Windows with only the basic drivers needed to load the operating system. Uses basic drivers for mouse, keyboard, display (VGA), mass storage, and default system services and drivers, with no network components. In Windows 2000, a log file will be created to track the progress of the system boot, which is located in the Windows 2000 folder.
Safe Mode with Networking: Loads the Safe Mode configuration, but also enables network devices and services. In Windows 2000, a log file will be created to track the progress of the system boot, which is located in the Windows 2000 folder.
Safe Mode with Command Prompt: Loads Windows in Safe Mode, and, after logging in, opens a command prompt instead of the normal desktop. In Windows 2000, a log file will be created to track the progress of the system boot, which is located in the Windows 2000 folder.Note: You should try booting to the command prompt only if you feel comfortable operating within the DOS environment.
Enable Boot Logging: Boots Windows with all of the normal files and drivers, but writes their status to a log file at each step. In Windows 2000, this log file is located in the Windows 2000 folder and is named ntbtlog.txt.
Enable VGA Mode: Boots Windows using a plain VGA 16-color 640x480 display driver for the highest level of compatibility with video cards. In Windows 7 and Vista, this mode is called Enable Low-Resolution Video. It is otherwise identical.
Last Known Good Configuration: Boots Windows using the last registry configuration that is known to work. This is a way of undoing problems created by installing incorrect drivers or possibly by registry corruption. It will not, however, fix problems caused by corrupted or missing files.
Use the arrow keys to move up or down this menu to make your selection, and then press Enter. If you need to update software or access the Internet while in Safe Mode, select "Safe Mode with Networking".

My el 1300g 02 starts up, gets to show icons and then restarts automatically. what could this be? how do i reset hard drive?


There is no way to reset a hard drive. There are many reasons that this could be happening. It could possibly be a bad hard drive or partition on the hard drive and could also be a corrupt operating system. A more detailed description would help further diagnosing the problem.

Windows start up screen keeps replaying on screen and never loads


This is a very short description without much detail, but you have a corrupted driver that loads, fails and causes the system to reboot.

Try tapping F8 while booting up and starting until you get to a menu list.

Try "restoring" if you can get to "Safe Mode" to last known good configuration

I have a desk top computer that shuts down when I try to sign on in 1 minute then it starts back up and shuts down again


that can be caused by a few things.
1. bad motherboard: Could be failures on the board, such as a popped capacitor, or a weakened power supply. If your video card is integrated into your board, you would replace them both.

2. bad memory: You could be losing ram integrity, and the computer could be rebooting itself. Try starting in safe mode, and also try starting in "disable reboot on failure" mode to get the error code from the blue screens.

3. corrupted windows: Your OS could be corrupt: a bad sector on the drive or a corrupted registry entry, or even a virus.

4. bad video card: The memory area of the video card could be affected just like the memory of the system board. Also, if your video is integrated onto your board, you will need to replace them both.

5. Thermal event (overheating): The cooling fans on your machine could be failing, causing the cpu to get hot and reboot.

Since you did not share any details about the crash, I cannot be specific about what is happening, but those are the 'usual suspects'

Blue Screen with various STOP error messages appearing.


This is a tough one to troubleshoot since there are several issues which can result in this error. Let me start by listing known causes.

Corrupt pagefile.sys file
Corrupt or wrong drivers for system devices. printer, camera, ect.
Corrupt program drivers, adobe elements, capture card software.
Bad System Ram Modules.

You didn't specify if you installed anything new, hardware or software but to trouble shoot this issue begin by download Memtest86. This will test your system boards memory for errors.
If your ram passes the test you might try removing other devices such as printers and its software. Testing the issue after each uninstall.

Last you can try replacing system files or performing a system repair using your operating system cd. If you need to run the repair option and need help just post back here.

Hope this helps.

Dell Dimesion 9200


it could be the corrupted OPERATING SYSTEM
to be sure
turn off the system
when you power it on start tapping F2 key
it will go in syatem setup
leave the system and monitor if it turns off or restarts
if it doesn't get your operating system reinstalled
and if it does restarts of shuts down we have to troubleshoot further
provide me your system's service tag located at the bottom pannel of your system, turn it upside down you will find a bar coded sticker which has a 7 digit alphanumeric number
