I got a Dell Studio 1558 for nearly 1.5 years. Since 3 months ago I keep getting 'pre-boot system assessment build 4124' when I start up the PC. Almost once a week so I have to abort it every time.
My PC is running smoothly as normal.
So may i know can I disable it on the setting somewhere in the system?
Try running the full diagnostics and see if you get any error messages. How to Run the Dell™ Diagnostics Utility
The pre-boot system assessment may be trying to tell you that you have an issue that may be happening.
What is a Dell Service Tag and how do I locate it?
