SMG4 buys (or steals) a new PC from an old man who threw his old computer away in a dumpster after it was dying. The new computer, however, detected a virus , in which SMG4 decided to keep the virus because he doesn't know what a virus is. The result came out when the computer opened up another dimension where it is all glitchy...
The video starts with Mario watching "Hotel Mario" scenes. SMG4 pesters the clerk for a new PC, but the clerk keeps replying that he has none. Eventually, the clerk tricks the crew into leaving.
At the castle Starman offers SMG4 a Mac, much to SMG4's refusal. He goes up to his PC, which the PC is, considered broken. So he tries to see if it is working. As it loads, the infamous Windows crash screen shows up. A text box comes up on the screen that says "SMG4 is gay". Turning the computer off, he finds an old man about to throw away a "washing machine", which is actually a PC. SMG4 gets it from the old man.
Starman checks on SMG4, and sees him joyfully dancing with his new PC. While loading it up, he encounters a virus. Unfamiliar with computer viruses, SM64 decides to release the virus instead of destroying it. The next day, the computer room has a glitchy texture. Toad got sent in, but doesn't come back.
The virus eventually spreads to the outside of the castle.
