In this video, I grab a real “slow laptop” case—an i7 Dell with a 1TB SSD and 8GB RAM—and I walk you step-by-step through how I troubleshoot it. The big question I always answer first is: is this a hardware issue or a software issue? I start simple: I check if the mouse/cursor is lagging, then I go straight to Task Manager to see what’s eating resources in the background, even when you haven’t opened anything yet. From there, I look at CPU, Disk, Network, and especially Memory usage. The CPU is low and the SSD activity is basically nothing, so I focus on RAM. I end a few background apps (like Copilot, Cloudflare, Teams) just to test and watch the memory drop, then I open Edge and a few tabs (Google, YouTube) to simulate real use—and the RAM climbs fast into the 50%+ range. My takeaway is clear: this laptop isn’t “slow” because the CPU or SSD is failing; it’s slowing down because 8GB RAM gets loaded quickly with modern browsing and apps. Since the laptop has 2 RAM slots (1 used), my recommendation is simple: upgrade to 16GB for a big improvement in everyday speed and multitasking.
