SignalLess is an AI-powered PC troubleshooting system built on the AMD Developer Cloud using ROCm and vLLM. The system combines a multi-agent CrewAI pipeline with a modern Next.js dashboard to diagnose and solve PC problems intelligently. The architecture consists of four specialized AI agents running sequentially on Qwen2.5-14B-Instruct served via vLLM on an AMD MI300X GPU. The first agent collects and analyzes system information from a custom Python diagnostic script that captures CPU usage, RAM, disk health, network stats, and running processes. The second agent classifies the problem as hardware, software, or network related with a confidence score. The third agent performs a deep diagnosis by cross-referencing user symptoms with real PC diagnostic data. The fourth agent generates clear, step-by-step fix instructions tailored to the user's specific system and OS. The frontend dashboard is inspired by NZXT CAM and displays real-time PC metrics including CPU load, RAM usage, storage partitions, network activity, and top processes alongside the AI diagnosis results. The backend is built with FastAPI, enabling seamless communication between the Next.js frontend and the CrewAI agent pipeline. Users download and run a lightweight Python script to collect their PC information, upload the resulting JSON file, describe their problem, and receive a comprehensive diagnosis in minutes. The entire LLM inference stack runs on AMD Developer Cloud with ROCm 7.0 and vLLM 0.17.1, demonstrating the power of open-source AI models on AMD hardware for real-world applications.
