Plenty of times. Usually, its a BIOS setting or bad RAM stick, both easy to diagnose and fix.Have you ever dealt with non-techie Windows users whose system is broken?
Not really. Sure, you can make Windows run like crap by installing every piece of malware under the sun, but hey, thats true for any OS. And I've yet to see a piece of malware actually cause a BSOD in the NT 6.1 (Vista/7/8) Kernel.The only reason you can say that is because OEMs ship systems with Windows pre-installed. If they shipped systems with Linux pre-installed, they'd be no different. And it only takes a few clicks for a non-techie Windows user to trash their system installing random crap from the Internet... yes, you must have Happy Fluffy Kitty Screen Saver right now!
