I recently upgraded from Windows 8 Enterprise x64 (US English) to Windows 8.1 Pro x64 (RTM, US English) on my lab workstation. It worked mostly fine for the last few days (since the upgrade), but this morning, after plugging in a USB-to-ATAPI/SATA bridge, it started to show BSOD errors periodically with the error message "Critical Structure Corruption". I've already removed the bridge from the USB port, but the PC has crashed twice since I did that.
I've never really dealt with Blue Screen errors. I know they're often caused by drivers or hardware problems. However, I've never really worked on debugging one. To fix it, I would normally just do a fresh install, but this is not a desirable option at the moment.
I know I'm probably handing you a dearth of information with this post, but that's because I'm not sure exactly what's needed to troubleshoot this problem. Let me know what's needed and I'll do my best to provide it to you through edits to this post.
