Disclaimer: I am a hardware/operating systems idiot, I'd love to learn but don't even know where to start.
I do all my software development on windows but like Ubuntu for browsing, chat, desktop management, etc. So I run Windows 7 in a virtualbox on Ubuntu 11.10 (originally installed via wubi).
I recently started on a brownfield java project, I am a total noob at java too so in the interest of minimizing new stuff to learn I created a new windows 7 vm and installed java, glassfish, and intellij IDE on there.
Within a few weeks I started having occasional blue screen of death crashes in the vm. When I reboot, the event log shows nothing that strikes me as odd. This got more and more frequent (during a deadline week too!) until I eventually rolled back to a very early snapshot (basically just the windows install) and reinstalled everything.
And guess what, I just had my first blue screen again.
Honestly, I don't even know where to go for help with this. Does anyone have any suggestions?
