I was recently working on a client PC and had to restart it due to a new application install. Upon restart, however, the computer blue-screened and displayed the following error message:
STOP: 0Ã—00000050 (0xCD3DD628, 0Ã—00000001, 0x804EFC9A, 0Ã—00000000)
At first, I thought this was something to do with the application we just installed, so I decided to restart the computer in Safe Mode and uninstall the app. It seemed to have worked because the BSOD went away, but only for a short time.
After a few more restarts, the message came back again! After doing some research, I found out that this error message basically means that Windows is trying to find a piece of data in memory and it cannot be found.
According to Microsoft, this error can be caused by faulty hardware, anti-virus software, a corrupted NTFS volume or a bad system service.
One thing to quickly determine the issue is if you recently installed any new hardware on the computer, such as a video card, RAM chips, etc. If so, it means that there is something wrong with the hardware, most likely defective.
In my case, it was faulty RAM and I was able to figure that out because I removed one stick of RAM at a time and then restarted the computer. After the bad one was removed, the computer booted up fine.
If it’s a bad driver install, you can press F8 and choose the Last Known Good Configuration option, which will roll back any recent driver installs or registry changes.
If it’s a system service causing the error, you can login using Safe Mode and then go to Services under Administrative Tools in the Control Panel and disable the appropriate service.
