Troubleshooting PC Display and USB Power Issues: Understanding the Problem
Are you experiencing frustrating moments when your PC powers on, but the display remains blank and your USB devices fail to respond? If so, you’re not alone. Many users have encountered a perplexing issue where their systems seem to power up—fans spinning and lights flickering—but the display refuses to show anything, and peripherals like wired mice remain unlit. Here, we’ll dive into this common problem and explore potential solutions.
Identifying the Symptoms
