I was attempting to download the recent Diablo III Beta. During the download process, an Interrupt_Exception_Not_Handled BSOD occured associated with ALCWDM64.SYS I attempted to download Diablo3 again only to have the launcher hang at 70%, apparently a common problem with the open beta. Less common is that during my attempts to resolve this problem, I generated a Windows Stop Error BSOD. This is the third batch of BSODs I have encountered when downloading programs. I have had similar problems in the past, both with a Starcraft II beta and with a Mechwarrior download service, each which would reproducible BSOD. Everytime I have tried to chase the problem down, I am advised to reinstall video drivers, which makes no sense because video is not involved, and I have had no success fixing the problem via video drivers. I got a history of BSODs resulting from downloads here. I can provide minidumps for the most recent BSODs if necessary. I could really use an explanation as to why downloads, particularly Blizzard beta downloads, are causing so many BSODs. Any help would be greatly appreciated. Thanks.
