Hi there peeps! I'm writing this lines in hopes for finding a solution to this unusual problem, I have been looking on Google, but none of the solutions have helped me... The Story: This is an Acer E5-553-1786 Laptop, and I decided to upgrade to Bios 1.31 in hopes of getting rid of my spontaneous reboots (WHEA 20 Error with Hyper Transport), and also, because I felt Spectre (Or Meltdown) patch was included in it. Sadly, I found that the damn thing just made the sudden reboots worse than before, getting a reboot once every 2 days, instead of once every month... So, my only solution was to downgrade the BIOS to see if I regain "system stability" (Man, this laptop sucks, I even have to hax the BIOS to enable virtualization... don't ever buy an Acer...) Now, after downgrading, TPM 2.0 now shows a yellow sign,a nd a code 10, saying the resource is already in use. What I tried so far: - Restoring to a previous image of windows 10: Nothing changes - Trying to update the driver: Says has the most suitable version - Ran troubleshooter: Did nothing. - Restoring factory defaults on BIOS: Nada... - Downgrading to another version, and then re-flasing the version that works (In my case 1.19): Nothing - Using a previous dump of settings I had with an utility called H2OUVE, and hopping for the best: Nothing - Clearing CMOS completely: Nothing I'm using Windows 10 Build 1703, as I'm waiting for 1803 to become stable enough to be usable. Latest drivers available for everything. I don't know if I did something incorrectly that might caused this, or I'm doing it wrong that I can't be able to restore this thing. Upgrading again is not an option for this BIOS since has tons of problems (Unless they release a new version... *sigh*) I attach pictures of device manager and the pin I used to clear CMOS in this particular model. Any suggestions? Thanks in advance Cya!
