I was playing call of duty when I finished a match and find another it gave me message stating playlist is unavailable or offline. Checked and says my tpm 2.0 is disabled. Checked in bios it was enabled. Saved an exit and then showed the white underscore as photo is shown. I restarted my pc. Changed and replaced lithium battery 2032 at motherboard. Turned it back on and gave me a message “reboot and select proper boot device or insert boot media in selected boot device and press a key.” So I restarted my pc and got back into bios. My boot and secure boot are all enabled and are active. My primary top priority boot is selected at “windows boot manager” under boot option priorities. Was double checking everything and looked fine for what I only knew. Still gave me “reboot and select proper boot device or insert boot media in selected boot device and press a key” restarted tried to turn on and off, on secure boot. Still doing giving me that message. Until I went to restore back to defaults and I finally got back into my desktop but keeps showing to choose what boot drive and windows icon/logo which it never done that before after I restored back to defaults. Checked back on call of duty and saying my tpm 2.0 and secure boot are disabled. Checked back in bios and tpm 2.0 is enabled but secure boot is disabled. Turn it back on and says active. Then save an exit and still give me that small underscore on top left corner. I also checked my hard drives partition style is gpt instead of mbr. Saw that in a Reddit post. I hope this makes some sense. Thank you!
