Let's ignore the "how" and focus on the consequences.
Remember that the Apollo spacecraft sent men to the moon with less computational power than you have in your pocket scientific calculator. With 64Kb of total memory and running at a whopping 43KHz ("Kilo-Hertz" ... you should be thinking "AM Radio") and at a time when "threads" was a word that described the shirt on your back they were nevertheless capable of getting them there and back.
But, how would I and/or We react to the sudden loss of our 10-core, 20-thread, 4.5GHz, 128Gb memory Intel i9-7900s?
(1) An entire generation of children would instantly become zombies as their streaming video, streaming audio, and cloud-based games would suddenly stop. The ensuing bloodbath would puzzle archeologists for millenia.
(2) All traffic control for airports and large cities would stop. Insurance companies would be inundated with claims for everything from fender-benders to the obviously-it's-the-airline's-fault death of some 500,000 people. Which will only be staved off by...
(3) The sudden end to all communication. Many homes today don't have POTS telephone connections, which may not matter since all the analog switches were replaced with computer-driven digital services decades ago. No telephones.
(4) Banking would be thrust back into the 1800s. You may not see the mortgage collector for years, but he/she'd show up in an effort to claim your home as an asset for a suddenly defunct bank.
(5) Our educational system would hicup, but catch up fairly quickly. Teachers who have been forced to use old, outdated textbooks would suddenly find themselves the center of attention as those books would be the only books to be had for a while. Once dead newspapers would come back to life as antiquated printing machines were dusted off and reporters would be considered important again.
(6) Not to mention fuel distribution, electrical distribution... the lights might come on (maybe, sucks to be driven by a nuclear power plant... or to live near one...) but the whole world would be sucking wind for a while. The resulting panic would drain every shelf in every store you can imagine. The chaos for the first week would be... impressive...
Except for government. True, the Snowdens and Wikileaks of the world would dry up very quickly, but the clowns would still be in control since their most frequently used technology is their pie holes. You just won't hear about the latest sex scandal that quickly.
How long would this last? Not as long as you think. There are a lot of scientists and engineers in the world, and it wouldn't take long to figure out alternatives that would move us from the 1960s space-race to at least the 80's hay-day of personal computing. (Intel 4040 processors, anyone?)
