Wow. Arrogant much? Who said anything about crashes being commonplace? It's a legit question. The infamous Windows 98 BSOD during Bill Gates' presentation proves that crashes will happen at inopportune times, even at "professional" level events.
There's lots of stuff they *could* be doing at the professional gaming scene to reduce the occurrence of crashes that "normal" people generally don't do. Not saying that they actually do any of this, but a list of possible things:
- They don't buy budget components like everyday people do and pay premium prices for premium components (i.e., RAM, SSD, Mobo, etc.)
- They don't have nearly as many peripherals attached to the computer that could cause problems with faulty drivers/software (i.e., printers, phones, webcams, external storage etc.)
- They have minimal software running on the computer, probably just the OS and the game and nothing else, so no crashes from background processes that may exist on "consumer" PCs
- They exhaustively test the RAM, storage, CPU, GPU, etc. using MemTest, etc.
- They don't use bleeding edge components that were released yesterday and may have unknown defects
