I have been running Cygwin (1.7.7) under Windows Vista 64-bit, SP2 for at least a year, and had no problems with my installation at all until today.

When I tried to install apt-cyg, I realized that I needed to get the svn client. During the installation of the package dependencies, Vista threw a blue screen of death.

I hoped this was a one-time occurrence, so I rebooted into Vista and tried to install svn again; same result.

Next I completely removed Cygwin's directory, and all Cygwin registry entries; at this point, I tried reinstalling the base Cygwin system again. During the installation of bash, I got another BSOD:

Apologies for the fuzzy pic, I had to shoot with my phone camera.

I googled for BSOD and Cygwin and found a post by Dave Korn mentioning that the only reasons Cygwin should cause a BSOD is because of either ioperm.sys or some USB utilities. I have neither on my system.

Every time I have tried reinstalling, Vista BSODs; I have not had problems installing any other software packages on this Vista machine. How can I get Cygwin installed again (without reinstalling Vista)?
