Advice 2: How to remove system error
The operating system is very complex, and errorsthat may occur are many and varied. To remove the error, when known, the cause is usually not very difficult. It is difficult to find the cause itself.
Log in to the system with administrator rights. Select Start = > Run. Type "msconfig". You will see the window "configure system". On the General tab, select "Selective startup" and uncheck the two options: Process the file System.ini", "Process Win file.ini" "Load startup items". Boot.ini don't do anything. "Load system services" do not disconnect. Click "Apply" and "OK". Then restart the computer. Check for errors.
If the error disappeared, again run the "configure system". Consistently include the option is disabled, and after each turning on one option, restart your computer and see if there are any error again. If there is, then, obviously, it is the last option enabled. If the error persists, that reason is not any of these options, and item 3 can be skipped.
For each option there is a corresponding tab. Open it. There you will see a lot of items are marked. Disable half of them and reboot. Determining which group of items causes an error, split it in half, half off, reboot and so on until until the exact cause of the problem will not be revealed.
