Hello. When i updated BIOS im having alot of issues. when i remove cord from outlet while pc is turned off, it wont boot untill i change RAM sticks, pc after update is turning off slow and when i'm restarting PC it takes about 10 minutes while it restarts itself. Can i somehow roll back my BIOS?

Hi:

You cannot roll back the BIOS as it indicated on the release notes.

Fix and enhancements:

- Provides latest Intel Microcode versions 0x2F for Sandy Bridge processors.

NOTE: Due to security changes, after loading this BIOS, older versions cannot be installed.

You have two options:

1. Install W10 in EFI mode by booting the W10 installation flash drive from the EFI USB boot source, not the legacy one.

2. Go into the BIOS and change the embedded security device (TPM 1.2) from 'Available" to 'Hidden.'

Below is the link to the service manual.  See chapter 2, page 10 for the location of this setting: (Device Security).

Thank you, i choose to try second method you told me by changing embedded security device to hidden in BIOS. It worked and im not having any issues now. Thanks again.
