Title says it all. Dell fucked up my PC last night (bit of an older model, 17R2) by pushing out an update for supportassist that made my pc freeze up and test the fans (left, then right) like it would in the real fan test. Basically, they fucked up something THEY made. Guess what was causing it? Dell Data Vault (part of supportassist) and when I deleted supportassist? It magically fixed.
