Buildapc

Hi. I finally decided to install Linux on my old PC (not booted in years). But when I plugged in my live USB and booted up, my PC is stuck here.

I tried booting up without a USB. Now a windows xp screen is asking me to start normally or boot with safe mode (3 safe mode options to be exact). Normal start does not work (the PC automatically reboots without warning). I choose safe mode with command prompt and bunch text shows up and ends with .../mup.sys

Any idea what should I do here? I have no use for my windows so I don't mind removing it. Also time resets every time I boot up the PC.
