Digital signage company NUVA publishes an article noting their experience with instability found in PC-based software systems:

NUVA ’s article named Software Stability

Content partially extracted from the article (emphasis in typeface taken from original article):

There is a false sense of security given to the end user when their display system seems to be working without a glitch when their display must retrieve content by pulling media from a central FTP / HTTP server [...] These multiple processes, under certain circumstances can destabilize a PC based display causing the entire screen to crash, show error messages, or just stop working.

[...] We can defiantly say, in our opinion, none of the software we have used is Crash-Proof, and no other company in the market today can Guarantee their software will NEVER CRASH.
