🛑 Why Does My Computer Freeze or Become Unresponsive?

There are several reasons why your computer might freeze, from hardware issues to software glitches. Let’s take a look at the most common culprits:

✅ Lack of available memory (RAM) – Running out of RAM means your computer has less space to handle tasks.
✅ Outdated or corrupt drivers – Old or broken drivers can cause system freezes.
✅ Overheating – If your computer gets too hot, it may freeze to protect itself.
✅ Software bugs or crashes – Some programs may have bugs that make them unresponsive.
✅ Viruses or malware – Malicious software can disrupt normal system processes.
