Constant rebooting of a computer can be cause by alot of reason the most common for this is due to oevrheating, to check if this is a overheating problem try to open the case of the tower and put a electric fan in front of the tower to coll it down then power ON thecomputer and if it booted up fine with a electric fan blowing on the tower we're sure that you need to add some colling device on the computer tower, But if still do the same thing the problem here is the power supply unit it needs a replacement already....

There are a variety of reasons you may need to reboot a Lenovo laptop.
These can include the installation of a new program, the dreaded blue screen of death or to free up memory that has been hijacked by a program that is now closed.
There are three ways to reboot and all are simple to accomplish.
Click on your start menu button on your screen.
Click on "Shut Down" or "Turn Off Computer."
Click on the drop down box if you are running a version of Windows before XP (such as 2000 or 98). Select the "Restart" option and then click "OK." On XP or later versions, click on "Restart."
The laptop will then reboot.
Press and hold down the "Alt," "Ctrl" and "Shift" keys simultaneously.
This will bring up the Task Manager.
Pressing and holding the same keys again will force the computer to shut down.
Press the power button to reboot the computer.
This feature should be used when the mouse has stopped working and you cannot access the start button.
Hold the power button in the "Off" position for approximately 5 seconds.
This will force the machine to shut down.
Press or slide the button again to reboot the laptop.
Use this process when you get the "blue screen of death" or the computer is not responding to either the mouse or the keyboard.
also
Bluescreen can be caused by a number of things
Check all power and data leads from motherboard to hard drive and all of your cd/dvd drives make sure connections are secure dust free and not faulty
computers need all power and data to travel through every working device and to finish its cycle
so any faulty lead will end in computer error or shutdown / fail to boot or to reboot on a cylce
Make sure your computers RAM modules are securely seated with no dust in the sockets also the Cmos battery has charge and seated with no dust in the sockets
some motherboards cmos batteries are soldered in
might be getting hot check your CPU make sure it has a thermal paste and a dust free and secure seating
Could be a memory dump you might be running to many programs at the one time placing to much strain on the CPU you might not have enough RAM random access memory
If you get your computer running to get a screen or even do it in safe mode
Restart your computer repeatedly tapping the f8 key to enter safe mode while the screen is black once in safe mode where the only things working will be your keyboard and mouse allowing you to attempt to repair your computer
If done properly the user should get to a screen similar to the below screen.
Select the option for Safe mode command prompt only
Windows Advanced Options Menu
Please select an option:
Safe Mode
Safe Mode with Networking
Safe Mode with Command Prompt
Enable Boot Logging
Enable VGA mode
Last Known Good Configuration (your most recent settings that worked)
Directory Services Restore Mode (Windows domain controllers only)
Debugging Mode
Start Windows Normally
Reboot
Return to OS Choices Menu
Use the up and down arrow keys to move the highlight to your choice.
select the safe mode option
You might have to many programs trying to or accessing the internet at the same time
scroll to bottom toolbar (bottom of screen) right click select task manager
applications you will see whats running
if you see anything you dont need running select end now and you might uninstall that specific
program if you or computer does not require it to run and
some unnecessary programs that could be jamming up your computer
also under processes see what is ticking over in the background again if you see something you
dont need to be running select end now and users you will see who is using your computer
you might need to add more computer ram
if you're not sure if a module is right for your system use the
Crucial Memory Advisor tool for a list of guaranteed compatible modules.
when purchasing any ram you should always ask if they can guarantee compatibility first you will need to select the manufacturer from a drop down list then select your product line
from a drop down list then select the model then click find it will take you directly to compatible ram also you will have an option to scan your system
might be getting hot
check you CPU make sure its securely seated and has thermal grease
http://www.hardwaresecrets.com/article/Thermal-Compound-Roundup-February-2012/1490
or it might be a virus right click in bottom toolbar select task manager applications to see what is running and processes to see what is ticking over

My lenovo keeps rebooting..when I select ''last known'' it shuts down and restarts the process again


Try to see if you can boot up the computer into safe mode. Keep pressing the F8 key as you turn on the computer and when it gets to the boot menu choose "Safe Mode".

If you can get into safe mode then go into the start menu and go into the system tools folder and then choose system restore. Choose a date on the calendar when the computer was last working properly and let the system reboot and hopefully that will take care of the issue.

If you can't get into safe mode or windows normally then that means windows is corrupted and you'll need to wipe out the drive completely and reinstall the OS and device drivers.

Laptop keeps restarting


  1. See if you can start in Safe Mode (hit F8 before Windows loads - best way is to keep tapping F8 after you power it on. You should get a menu with "start in Safe Mode" as an option.
  2. Once booted in safe mode go to Control Panel, System, Advanced, ;Startup and recovery'.
  3. Click the Settings button and remove the tick from the "Automatically Restart" box.
  4. Click all the OK's to get back to Control Panel.
  5. Reboot as normal and the system should display an error code. Post that error code here and we can have a look at it.

Restarting


Try going into safe mode and see if the machine will keep running. If it does then start disabling start up programs until you find the culprit. If it won't keep running in safe mode then suspect hardware fault and take it in for repair.

Have you made any hardware/software changes lately? If answer is no, reboot the pc and hit F8 a couple times. This will give you a list of options. Use your arrows and highlight last known good configuration and hit enter. See if your pc boots ok. If you don't have that option or it doesn't boot ok, Repeat the process to get the list. Use the arrow keys to higlight Safe Mode and hit enter. Your pc should boot to safe mode. Click on Start>progams>accessories>system tools>system restore. Choose a safe date about 3 days ago and do a restore. Wait until it's done completely! and see if it's working ok. If this fixed your problem please rate as fixed. If you need more help with this just add a comment and I'll be glad to help out. Thanks.
