Ok, so here is my situation. I like to run a certain MMORPG overnight, but my hard drive is very annoying, its kinda rattles and hums, and i would rather not listen to it while i sleep. I have a 128GB flash drive and it occurred to me that i might be able to install my OS (windows 8.1 64 bit) and the game on my flash drive and boot the PC up from there, that way my hard drive could turn off and i could use the silent USB drive. Is this possible? Im more of a hardware guy than a software guy, so i could really use some help. Thank you.
