When Windows 7 fails to boot then start with the steps given here: Troubleshooting Windows 7 Failure to Boot - Windows 7 Forums

To find a location (e.g. Event Viewer, msconfig) type it in Start Search box.

1. Check for infection by installing Malwarebytes, update, run a Full Scan - in Safe Mode with Networking if necessary.

2. Many issues can be solved by running a free lightweight AV like Microsoft Security Essentials with the Windows 7 Firewall for best performance.

3. Establish a Clean Boot by unchecking everything in msconfig>Startup except AV: Startup Programs - Change. After reboot enter msconfig>Services, check the box to "Hide All MS Services," repeat above steps. Check back periodically that nothing has written itself in to either list, turn it off in its Program Preferences or Uninstall it. A program can wait to start until you click on it. Freeloaders slow startup, can be a drag on CPU/RAM, cause issues and spy on you. If you have a question about an item google to find out what it does.

4. Study the Event Viewer>Custom>Admin view for repeat errors to google text and ID# to find out how others have resolved them. Event Viewer - Open and Use in Windows 7

Look for issues cued in Action Center in bottom-right System Tray.

6. Type "Solutions" in Start Search box to see if any have been cued for Problems reported or not. Always report problems when asked as Windows 7 is interactive this way.

7. Use Process Monitor for Application Failures, File System issues, Registry issues, Boot logging, Memory Stack issues, and misleading Error messages which is demonstrated in this Process Monitor Demo - YouTube. Type Resource Monitor in Start Search box to narrow down resource hogs.

8. Test your hardware by running memtest86 CD for 5-6 passes or overnight: RAM - Test with Memtest86+. The tutorial will show you how to test individual RAM sticks and slots. Check the slots for debris.

10. Check all cabling is securely connected and in good condition, try reinstalling suspect hardware, swap RAM sticks, unplug extra HD's, peripherals, CD/DVD drive to see if problems disappear. Unplug or remove any floppy drive.

11. Check temps for overheating by installing Speedfan. If running hot blow dust out of the case using canned air or clean out laptop dust, check all connections carefully avoiding static discharge to components by touching case first, upgrade or reseat RAM checking for debris in slot.

12. Check for any errors in Device Manager after Showing Hidden Drivers on View tab.

17. As a last resort before reinstall try a Repair Install which can fix most problems as it reinstalls the OS while keeping all programs, files and settings in place.

18. Consider a Clean Reinstall which is actually better than getting a new computer with today's bloated factory pre-installs. The steps given are Best Practices based on countless thousands of reinstalls helped with here and the same for both OEM and retail.
