Need Help to figure out my BSOD problem.

The error indicated fileinfo.sys
I would suggest to try running Startup Repair from the installation DVD. Startup Repair will check the filesystem on the disk (FILEINFO.SYS errors). If it doesn't complete successfully, then you'll have to run chkdsk /r from the Command Prompt.
