Won't boot past Alienware screen
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.
Do you mean the initial BIOS Posting screen? Can you access the BIOS settings? Can you press F12 on Boot and run ePSA Diags?
Only the monitor, USB keyboard, and mouse should be connected .
Most common instance of this is corrupt or DEAD hard drive.
Disconnect the hard drive and see if it post's with no hard drive error.
If it doesnt there is something worse wrong.
I had this happen on the same day. I've the initial diagnostic with no errors found. Currently, it's running memory test and has several hours left.
Follow up: I've now completed all diagnostic with no reported eerrors. When I hit f12 and select Windows boot menu it does nothing.
Be sure the Windows Boot Manager is still at the top or #1 Priority
Aurora-R6 : Hard-Lockup and crash while gaming (SOLVED)
one of the latest Windows 10 Updates does this to alot of Systems. some people report the same behavior. try to disable Secure Boot. but even if you are able to boot, you guys should not run your PCs with Secure Boot disabled. try to uninstall the latest Windows Updates or use the Backup and Restor Funktion.
It seems like Creators Update really wants SecureBoot and GPT disk on UEFI-capable systems.
