Blue screen errors, or stop errors, on Windows-powered devices are resolved by setting the system to start up using the last known good configuration, using system restore or rolling back any newly installed device drivers to the previous version. Other ways to resolve a stop error are to check the hard disk for data corruption, scan the system for viruses, apply the most recent Windows updates and service packs and updating hardware drivers to the latest version.
An outdated BIOS is another common cause of stop errors, and updating the BIOS can resolve the issue. Test the integrity of hardware connections including internal data and power cables, memory modules and expansion cards by opening the case of the PC if possible and reseating each component. Inadequate amounts of hard disk space can cause data corruption and other serious issues that trigger a stop error. Viruses are capable of infecting the master boot record or boot sector of a hard disk, rendering the system unable to launch or operate properly. When the system is unable to boot into Windows, use a bootable antivirus utility to scan and cleanse the system of viruses.
Stop errors are generated by the Windows operating system when an error is encountered that prevents Windows from booting properly. Stop errors are caused by either software or hardware malfunctions and are commonly attributed to hard disk corruption or failing RAM.
