Love this site BTW! On this Laptop had to update to be able to upgrade to Windows 10. However after I upgraded the BIOS from A03 to A09 I started have issues randomly of BSOD stating System Halt Contact Hardware Vendor. All drivers are up to date and still running Windows 7 Professional. I've pulled my hair out on this one including clean installs, changed memory modules, but I know everything was perfect until I flashed the BIOS. Any and all helpful comments will be appreciated.
