Debugging Windows Desktop Application

i need to fix my program issue , The problem began a month after the project's completion by the previous developer, who is no longer available.

Key Aspects to Consider:
- The application experiences a Blue Screen of Death (BSOD) which previously occurred and seemed to correlate with a date/time issue.
- Potential causes include: time-stamped DLL files, the source code, or patched files.
- The issue is likely minor and can be fixed with a bit of investigation.

Ideal Skills and Experience:
- Extensive knowledge of Windows desktop application development.-kernel level
- windows drivers
- Proficiency in debugging DLL files.
- Experience with identifying time-related issues in software.
- Previous work with resolving BSOD occurrences in applications.
