15 R2, fans stop computer

Question

Soon after I turn on this 2016 15 R2, the fans seems to do a test? They come on for a short time which freezes the computer. When they go off all is OK again. This happens fairly often. Can I stop this from happening?  It has only done it since the last update. Thanks.

Hi @Morris63 welcome to this free user to user Alienware laptop discussion forum. This is not Dell Support.

POST (Power On Self Test) is the initial set of diagnostic tests performed by the PC right after it's powered on, to check for any hardware related issues (but not all hardware is tested). The Alienware 15 R2 (2016) fans are tested (briefly switched on) as part of POST. This is normal.

Dell provides a more comprehensive ePSA Diagnostic having entered the Boot Menu during Alienware splash screen by holding down the F12 key. ePSA Pre Boot System Assessment Dell Overview (Official Dell Tech Support) - YouTube

If this "freeze" only exists during POST, and not in the Windows 10 or 11 Operating System, not sure you want to invest more time by running Windows Reliability Monitor. How to use Windows Reliability Monitor to identify software issues | Dell UK

Try running an ePSA/Diagnostic test on the system, click here to view a Dell article that explains how to run this test. Let me know if you receive any errors.
