When installing a new Windows operating system, selecting the Safe Mode boot option helps identify driver problems. Then the first step is to identify the device or driver that is causing the problem during startup (use Boot Logging to create a log file to identify the device or driver). Next, uninstall the driver by locating the driver file in the registry. Then attempt to determine if the device or driver can be disabled (by checking Device Manager). If the device or driver cannot be disabled, disable it by checking the corresponding box in Device Manager (or the corresponding box in the add/remove programs list). If all else fails, try booting into an older version of Windows to see if the problem persists.
If the system is a laptop, disconnect the battery or power cable. The battery can cause problems by having a low charge. This will cause the system to start normally (but will not be able to continue running the system). The power cable could be bad. This causes the system to perform some basic initialization, but will not continue running the operating system. Once you have located the device or driver causing the system to crash, you can work on getting it installed properly. If the issue is with the operating system, you can apply a new version of the operating system and the problem will likely be fixed. If the device or driver cannot be removed, you can reinstall the operating system by using the CD that you downloaded the operating system from.
Pcouffin.sys is a Windows driver. A driver is a small software program that allows your computer to communicate with hardware or connected devices. This means that a driver has direct access to the internals of the operating system, hardware etc.The free file information forum can help you determine if pcouffin.sys is a Windows system file or if it belongs to an application that you can trust. If the problem does not cause Windows to crash, and after startup has completed, you can review the ntbootlog.txt file. Look for any signs of problems loading device drivers. If you find problems, go into Device Manager and disable the device or uninstall the program, then reboot again. If the problem does not occur then you know it was that device and you should check the vendor website for new drivers or known issues. 827ec27edc
