Post-Hardware Upgrade Diagnostic Assistant for PC Stability

Users often face unexpected system instability (stuttering, screen blackouts, random reboots) after upgrading PC components like GPU and PSU. Existing troubleshooting is complex, time-consuming, and often leads to repair shops. A SaaS product could offer specialized diagnostics for post-upgrade scenarios by analyzing system logs, detecting power delivery anomalies (if accessible), checking driver compatibility against new hardware, and performing targeted stress tests. It would provide plain-language explanations of the root cause and guided, actionable steps to restore system stability, reducing user frustration and the need for professional intervention.
