I think Microsoft removed System Information from Windows 8.1! I've been all over this fucking thing and can't find it! How am I supposed to see my bios version without rebooting and going into setup? What a stupid thing to do! At least on Windows 8 it was there, although hard a fuck to find! Shit!
They can't stop me! I have Clippy on my side! So it seems they have removed it from any and all GUI menus in 8.1 but they left msinfo32 there! So, Windows Key --> R --> msinfo32 --> Enter --> Give the finger to MS!
Try CPU-Z. That can usually show you most CPU/MB things.
