I upgraded a Latitude e5420 to BIOS a02, After the upgrade, the laptop will get to the Dell splash screen, then reboot...and just keep rebooting to the splash screen. The hard drive light blinks before each reboot.
I Reinstalled Windows 7, then upgraded the BIOS to A14 and it is doing the same thing. Cannot get past the splash screen, then rebooting.
I ran all the onboard diagnostics and the hardware passed all tests.
Any help would be greatly appreciated
