My Windows-based application stack has started throwing errors and I can’t pin down the root cause. I’m looking for an experienced Windows specialist who can jump in remotely, diagnose the software conflict or corruption, and guide me through a clean, permanent fix. You’ll need solid knowledge of recent Windows builds, common DLL and registry pitfalls, and standard debugging tools such as Event Viewer, PowerShell, and Sysinternals. If additional logs, crash dumps, or version checks are required, just let me know what to capture and I’ll supply them promptly. The aim is straightforward: identify the problem, resolve it without compromising existing data, and leave me with a brief set of steps so I can reproduce the fix if the issue reappears. If you can ...

I need a compact, production-ready PCB that brings together an ARM Cortex MCU with a temperature sensor, 3-axis accelerometer, optical heart-rate monitor, microphone, speaker and on-board flash.

I have a small quiz app built with plain JavaScript (HTML, CSS, and JS). There is no database; it runs entirely in the browser. I originally followed a YouTube tutorial and then replaced the questions with my own. It mostly works, but there are three problems: 1. At the end, my score is too high. The score increases even when I answer incorrectly. 2. The quiz sometimes skips a question, and the “Question 2 of 5” counter is incorrect. 3. When I click Restart / Play Again, the score does not reset to zero; it keeps the previous points. The files are only on my Windows 11 laptop. I don’t really use GitHub. The project is roughly 300–400 lines in total. I need this completed within 1–2 days. In your bid, please tell me what you think is causing problem number 1...
