Method 1 – Safe Mode
To start your computer in Safe Mode:
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 press 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 option you want, and then press Enter. For more information about options, see Advanced startup options (including safe mode).
4. Log on to your computer with a user account that has administrator rights.
When your computer is in safe mode, you'll see the words Safe Mode in the corners of your monitor. To exit safe mode, restart your computer and let Windows start normally.

Method 2 – Clean boot
Note If the computer is connected to a network, network policy settings may prevent you from following these steps. We strongly recommend that you do not use the System Configuration utility to modify the advanced boot options on the computer unless a Microsoft support engineer directs you to do this. Doing this may make the computer unusable.
a. Log on to the computer by using an account that has administrator rights.
b. Click StartCollapse this imageExpand this image, type msconfig.exe in the Start Search box, and then press ENTER to start the System Configuration Utility.
If you are prompted for an administrator password or for confirmation, type your password, or click Continue.
c. On the General tab, click Selective Startup, and then click to clear the Load startup items check box. (The Use Original Boot.ini check box is unavailable.)
On the Services tab, click to select the Hide all Microsoft services check box, and then click Disable all.
Note Following this step lets Microsoft services continue to run. These services include Networking, Plug and Play, Event Logging, Error Reporting, and other services. If you disable these services, you may permanently delete all restore points. Do not do this if you want to use the System Restore utility together with existing restore points.
Click OK, and then click Restart.
Step 2: Enable half of the services
a. Follow steps 1a and 1b to start the System Configuration utility.
Click the Services tab, and then click to select the Hide all Microsoft services check box.
Click to select half of the check boxes in the Service list.
Click OK, and then click Restart.
Step 3: Determine whether the problem returns
If the problem still occurs, repeat step 1 and step 2. In step 2, click to clear half of the check boxes that you originally selected in the Service list.
If the problem does not occur, repeat step 1 and step 2. In step 2, select only half of the remaining check boxes that are cleared in the Service list. Repeat these steps until you have selected all the check boxes.
If only one service is selected in the Service list, and you still experience the problem, the selected service causes the problem. Go to step 6. If no service causes this problem, go to step 4.

If the problem does not occur, repeat step 1 and step 4. In step 4, select only half of the remaining check boxes that are cleared in the Startup Item list. Repeat these steps until you have selected all the check boxes.
If only one startup item is selected in the Startup Item list, and you still experience the problem, the startup item that is selected in the list is the service that is causing the problem. Go to step 6.
If no startup item causes this problem, a Microsoft service most likely causes the problem. To determine which Microsoft service may be causing the problem, repeat step 1 and step 2 without selecting the Hide all Microsoft services check box in either step.
Step 6: Resolve the problem
After you determine the startup item or the service that causes the problem, contact the program manufacturer to determine whether the problem can be resolved. Or, run the System Configuration Utility, and then click to clear the check box for the problem item.
