Hey my laptop starts and then a blue screen occurs and system restarts before showing the desktop what to do, I have tried everything said in different forums but nothing works, please help me!Does it sound familiar to you? If it does, then you know we are talking about the dreaded ‘Blue Screen of Death’ (BSOD) error. One of the common Windows OS errors, the BSOD casts a ‘STOP’ error screen with error details on it, shutting down the computer forcibly. In other way, the Windows shuts down itself in order to prevent additional damage, causing severe problems such as full, partial system crash and data loss.Understand the BSOD error:The BSOD error can befall due to numerous reasons such as incorrect Windows installation, incompatible.dll files, hardware or software, virus infection, faulty/corrupted device drivers, and Windows Update among others.Fix It Procedure:Before performing the procedure, ensure that you have no above mentioned problem. If there are damaged.dll files, remove and reinstall them. Use the Windows disc to repair and/or reinstall the complete OS. Before, you do remove and reinstall, back up your data to an external drive or CD. Update the device drivers, if these are faulty or corrupted then download and install new drivers from the Microsoft’s or the manufacturer’s website.If you suspect that your machine has caught virus (es), then run a full system scan from your anti-virus or anti-spyware and delete the infections if there are any. For corrupted hardware/software, replace them with the new one (only if they are faulty, if they are not then repairing them). Regularly run Windows Update for additional updates and smooth functioning of the computer.If everything is fine, then follow the instructions below:o Reboot computer in the ‘Safe Mode’. To access safe mode, you need to continuously tap the ‘F8’ key on the keyboard while the Windows is restarting. Start tapping the key before the Windows logo appears.o Go to the ‘Start’ menu, and click on ‘Search’o When the Window appears, on the left hand side you will see different options, choose all files and folders, type ‘ctfmon’ or ‘ctfmonb’ (without quotes) in the box, and click on the ‘Search’ button.o When the search is finished, delete all the ‘ctfmon’ fileso Now, in the search box, type in ‘blackster’ (without quotes) to look for the blackster files, and click on ‘Search’o Delete all the blackster files if there are anyo Now go to the ‘Start’ menu> click on ‘Run’o When the window appears, type ‘msconfig’ (without quotes) in the box, and click on ‘OK’o Click on the last tab that says ‘Startup’o Uncheck all the options in the Window and click on ‘OK’o It will prompt you to reboot the computer, do it to let the changes take effecto Restart computer in the normal modeo It is recommended that you restore your computer to factory defaults settings.Additional Tidbits:o Excessive heat can result into the BSOD error, so put a cooling fan close to the computer if you don’t want to change its location. Or you can shift the computer into a room/place where there is enough cooling available.o The error can also be caused due to dying hard drive or low/faulty RAM. Replace the dying hard drive or faulty RAM or use additional RAM if it is low.o Before you perform any step, back up your data or restore your computer to an earlier date/time so that you have access to your data if anything goes wrong.o Don’t think that Windows Updates is a useless stuff on your machine. Updates are necessary as they include latest patches, drivers, security definitions, and enhancements for your system. These help your computers perform optimally and without glitches.If nothing works, then I recommend that you don’t try to resolve the problem by yourself. It may not turn out as a very good experience besides consuming a lot of time. Consult a certified technician or expert to save you from frustration.
