The Blue Screen of Death in Windows
Over the years we all have experienced the Blue Screen of Death if you are using a Windows Based operating system. Most of the time this start up error is based upon an error that is not that serious which has occurred in a program running on your system, to a very serious problem like a hard drive failure. So make sure you have backups!
The best practice when this Blue screen of death occurs is to have your windows installation media, like the CD, DVD or USB Thumb-drive to boot the system with. ( A lot of Computer professionals will start off with trouble shooting the system by pressing the F8 key on startup and using the advanced windows startup to different startups like safe mode and safe mode with command prompt and so on. This wastes time in the long run, because 60% of the time it will not work, period. ) Here is my simple way that works everytime unless the hard drive is hosed. I will use Windows XP for this example.
Insert the Windows media, boot from the media, when the windows installation starts, let it get to the options of what you want to do, install a fresh copy, or repair an existing installation. We select repair an existing installation by typing in R. The system will then go to the Repair system which is a lot like DOS. At the C:\ prompt type in CHKDSK / R which looks like this: C:\chkdsk /r
Click enter, the system will ask you are you sure you want to run this. Type in Y, and let it run. It will take anywhere from 1 hour to 10 minutes based upon your system. When it has completed 90% of the time you system will be fixed. The other 9% means that the Master Boot section was hosed. This is not a problem. What we do next is boot from your installation media again, select R for the repair an existing installation, and at the command prompt type in FIXBOOT, should look like this C:\fixboot The system will ask you are your sure, type in Y and click enter. After it finishes, type in EXIT and reboot. Your system will be back to normal. For the other 1% which this did not fix, you will need to install a fresh copy of your Operating System, and most of ther time this will not work because your hard drive has failed, or is failing. When I have a system that none of this works, 100% of the time the Hard Drive has failed. So I replace the drive with a new one, install my OS, and applications and I am good to go.
