I believe it will be a very frustrated experience to come across Windows system crashes when using the computer. But don’t worry! Here, six methods will be discussed on how to solve such problem.

1) Start the computer by using the Last Known Good Configuration feature
Boot your computer and hold your “F8 Key” which should bring up the “Windows Advanced Options Menu”, then use the ARROW keys to select Last Known Good Configuration (your most recent settings that worked), and then press ENTER. Hence, the system will automatically use the registry backups in normal mode to restore the entire system, solving the Windows system crashes problem easily.

2) Repair system files
When trying to solve Windows system crashes problem, the Last Known Good Configuration will only repair the registry data. But if there is something wrong with the system files, it will result in system instability or failure to log in the system. So a scan with the system command “SFC” is needed. Once a file is found to be missing or damaged, you will be prompted to insert the installing CD to restore the original file. You can go to Start -> run -> type “sfc /scannow” and then “Enter” to begin the scanning. By the way, please remember to use a patched CD to restore the system if the operating system in the installing CD is an older one, avoiding a restore to an older version.

3) Replace user
We know that Windows registry always contains system branch and user branch. Sometimes, some users themselves configure the current system environments, which cause kinds of malfunctions when logging in the system. At this time, please do not rush to reinstall the entire system. A simple replacement of user account will solve the problem. You can go to Start -> Control Panel -> User Account to create a new account and then log in the system. But you must know that the “My Documents” folder and some private data with the previous users account are stored under the directory with the previous account. You can first back them up or open “C:\Windows\Documents and Settings\Username” after logging in with your new account.

4) Restore DLL registration status
There are two categories of DLL files existing in the system: one is not-required-to-register standard DLL file, and the other is required-to-register ActiveX DLL file. The latter will leave some related data in the Windows registry. Once corrupted or missing, errors will happen when requesting these files. And it will be a little annoying to re-register these DLL files, but you can easily solve it with the below method: open Notepad ->edit the below codes ->save as “regdll.bat” ->executive it ->reboot your computer to restore the crashed computer.

5) Completely restore original Windows Registry
You can restore the Windows registry to the original status (a status that has just installed the system). Considering that the files in the registry database are always locked after starting up the computer, it is recommended to take this action in DOS mode. If dual systems, you can directly operate in other good operating system; and users with NTFS partition can use the Recovery Console. With the prompt of command lines, use the CD commands to transfer the current directory to “%windir%Repair” and then perform the following commands one by one:
copy sam %windir%system32config
copy system %windir%system32config
copy software %windir%system32config
copy default %windir%system32config
copy security %windir%system32config

6) Use the System Restore feature
Go to Start -> All Programs -> Accessories -> System Tools -> System Restore -> select “Restore my computer to an earlier time” and then click “Next” to restore the crashed computer. If it is impossible to even get into Windows safe mode, please contiguously press “F8”and type “C:\windows\system32\restore\strui.exe” when coming to “Safe Mode with Command-line”, last press “Enter” to run a system restore process.

With the six methods above, you can easily solve Windows system crashes problem. But in my opinion, it is necessary to know how to avoid a crashed computer rather than how to fix it: timely delete the unwanted programs / unnecessary startup items / useless system junk files. Moreover, please do remember to defragment your computer to make sure that all files on the hard disk always stay close together and then easier to get access to.

In conclusion, there are many ways to solve Windows system crashes problems before reinstalling it. But it is much better for you to know how to easily avoid a crashed computer with some simple measures like defragment your computer regularly.
