A critical error has occurred - what to do?
If a critical error has occurred on your PC, this can have many causes. We'll show you how to fix the problem.
Critical bug caused by virus
A virus on your PC can lead to a critical error on both Windows 7 and Windows 8.
- You can use the AVG Anti-Virus tool to check your computer for viruses. You can find detailed instructions under this link.
- Most viruses can be removed directly with the program.
- However, if your PC is so heavily infected that the anti-virus tool cannot solve the problem, only formatting your computer will help. In our practical tips, we explain how to format your Windows 7 or Windows 8 hard drive.
Error messages have many causes
Virus infestation is the most common cause of a critical error on Windows. However, if your PC is virus-free, the following problems could also be the cause.
- A faulty Windows update can lead to a critical error. In this case, Microsoft would fix the problem with a hotfix.
- Your hardware does not match or is faulty and causes the error message.
- Your windows installation has partially failed. In this case, you should restore Windows.
- System recovery is also possible under Windows 7.
