A capacitor in a computer is like a tiny energy vault—storing and releasing electrical charge precisely when needed. You’ll find them scattered across the motherboard, graphics card, and other components, quietly keeping things stable.

🔌 What it does:

• Stores and releases charge: Helps smooth out voltage fluctuations so parts like CPUs and memory run reliably.
• Filters noise: Reduces electronic interference, especially in audio components.
• Supports timing: In circuits like clock generators, capacitors help keep signals crisp and accurate.
• Powers momentarily: Can keep settings alive (like in CMOS batteries) when the power goes off.

📦 Types you might see:

If one fails, it can cause random reboots, crashes, or even prevent the computer from turning on—like a backstage crew gone missing.
