In this article, we’ll break down the top 5 signs your system needs expert attention — and how PC Doctor London can help.

⚠️ Sluggish Performance – A Sign Your Computer Needs Professional Repair

If your PC boots slowly, apps freeze, or web browsing feels like a chore, that’s more than just age — it could indicate a serious issue.

Failing hard drive or SSD
Malware infections
Corrupted system files
Overloaded RAM or driver conflicts

🔥 Overheating or Loud Fans? You Might Need Repairs

Is your computer too hot to touch or constantly sounding like a jet engine? It’s trying to tell you something.

Warning signs include:

Hot air from vents
System shutting down
Fan noise at 100% even when idle

Overheating can permanently damage your motherboard, CPU, or GPU. When internal cleaning doesn’t help, professional thermal re-pasting or fan replacement may be needed.

💥 Crashes, Freezes & Blue Screens (BSOD)

Bad RAM
Failing power supply
Virus infections
Driver conflicts

A professional repair service can run diagnostic tests to isolate the problem and resolve it without guesswork.
