Start the computer in safe mode and run System Restore

1. Click the Start button , click the arrow next to Shut Down, 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 must press F8 before the Windows logo appears. If the Windows logo appears, 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 Safe Mode, and then press Enter.
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.
5. Click the Start button , type "system restore" in the search box, click System Restore, and then click Next. If you're prompted for an administrator password or confirmation, type the password or provide confirmation.
6. Choose a restore point when your PC worked as expected, click Next, and then click Finish.
7. Restart your computer normally.

If these steps solve the problem, you're done. If not, try repeating the steps and selecting an older restore point (if one is available). If that still doesn't solve the problem, contact your computer manufacturer or technical support for further assistance.

Try in the safe mode. If the system freezes up in the safe mode, run a Diags on the hard drive. Most Laptops have inbuilt Diags for the hardware available in the boot options screen. If the Diags pass, do an OS re-installation. You can also try system restore, but the issue can come up again. If you have data, you can try safe mode. If it works, back up your data, and then reinstall the OS.
If the system does not freeze up in the safe mode, go to msconfig, disable all Startup items and non-microsoft services. Startup in the normal mode. Enable the Startup programs one after the other, and you will be able to identify the problem creating application. This can also be a problem of virus infection. So when in the safe mode, after disabling all Startup programs, and un-hiding file extensions and system files, run a virus scan. MalwareBytes is a free and very effective program that can be installed and run in the safe mode.

Please Be aware that when using this option you will permanently lose access to any e‑mail messages that were stored on the hard drive (ie. like through Outlook) or encrypted files that are on that account.
