Odd Boot Problem following crashes

[EndTrophy]

The Problem:

Following crashes Crashes/problems (restarting during a windows update, bad overclock causing crash, GPU crash etc), my BIOS will sometimes switch the boot order of my drives. I suspect my bios, boot loader, or windows install is corrupted but I do not know what the course of action should be. I've seen that BIOS updates have bricked computers or caused other complications so I am wary of trying that. I have also never reset my CMOS before however. I'd rather not do a fresh install ifif possible because that would be a bigger headache.

Things to note:

• My motherboard bios (ASUS z170 ws) is not at the newest version
• Crashes/problems I've had in the past  would also cause the intel rapid storage RAID menu to show up even though I've never enabled it and do not have any RAIDs setup; i.e it has only shown up following some crash or complication.

Weird.

Clear CMOS and update the BIOS.

How likely do you think a BIOS update would cause problems?
