I attempted to log into my workstation this morning only to discover, when the monitors woke up, that I had bluescreened. My Workstation is Windows 7 x64.
The error message was:
PAGE_FAULT_IN_NONPAGED_AREA
Boy, that sounds bad. But then blue screens are always ominous. I rebooted and attempted to access the advanced options. I was taken to the windows error recovery menu, and my only options were to attempt "Startup Repair" or Start Windows Normally.
Startup Repair starts. Eventually I get a second prompt asking me if I wanted to restore to the last known good configuration. Clicking Yes or Cancel didn't produce much difference. Both lead to blue screens, and I've seen both SYSTEM SERVICE EXCEPTION and MEMORY MANAGEMENT.
So I Tried to start Windows normally, and here I got a bluescreen stating:
Windows did not find any installed, licensed language packs for the system default UI language.
Yesterday I installed our in-house created signature control software (our software manages consent forms, so there's an option to attach third party devices to digitally sign documents). The other devs are on Win7 x64 and have it installed with no problems. I'm skeptical that it caused this; I installed it and worked for several hours before logging out for the day. But it is the last significant change I made (and the only one I can think of in weeks).
Lastly, we just tried booting from a CD to do a repair that way. I've been sitting at the "Microsoft Corporation" + progress bar prompt for 20 minutes, and Windows (or whatever Windows loads to do a repair/recovery) still hasn't loaded.
I'm unclear what the next step should be. I have no way to run any further diagnostics, it seems.
addendum finally got the machine to boot from CD and tried to initiate a repair. There is no Windows 7 on c: listed in the System Recovery Options dialogue. It is showing one on D, though (I find this puzzling; D: was just dataz and stuff). Thinking about it more, I'm pretty sure there's a RAID array (RAID 5? I'm not 100% certain) with C and D being partitions on that array. C was windows/apps, D was pretty much data. This dialogue has a load drivers option. I'm wondering if I need to load RAID drivers or something.
