Yeah, it has the flash bios button where you just need the motherboard and psu to flash the bios but, that didn't work I let it sit for 2 hours when it said it should only take 5-7 minutes and then when I tried booting it wouldn't work at all. So, I tried to flash the bios with the button again but, still wouldn't work. That's when I sent it back.
I haven't tried to enable secure boot but, from some quick google searches it looks like I have to use the bios to do that. Is there a way to do that just through windows? Also, forgive my idiocy but what is CSM?
Thanks.
