Got a call today from a friend who I installed TP for on Toshiba L55-b5267, core i5, 6 gb RAM, saying it had crashed with blue screen "IRQL Not Less or Equal" while playing YouTube music.
We ran through the gamut of onboard and disk Repairs including Startup Repair, System Restore, Refresh and Reset and nothing would get it started.
I had made him a Macrium backup image but the PE disk wouldn't boot with an error that sounded like Secure Boot, which we turned off in BIOS, yet the disk then hung repeatedly at 2/3 loading.
Finally we reinstalled but this time I did not supply any drivers not provided by the installer or Windows Update which all I assume are vetted for TP. On the previous install I had imported a missing 8.1 chipset driver from Toshiba website.
Regrettably there was no way to rescue the Bugcheck file so would appreciate any suggestions on what to look for now in the fresh install. I also still have access to the Macrium backup image of the crashed install to restore to a partition if there is a reason to access it further for comparison.
Thanks for any feedback.
