Top 5 Computer Problems & How to Fix Them

Every day, our IT technicians visit homes across Ajman, Dubai, and Sharjah to fix computer problems. After hundreds of callouts, we've identified the problems that come up again and again. Here are the top 5 — and what you can do about them.

1. Computer Running Slow

A slow computer is the most common complaint we receive. The culprits are usually:

• Too many startup programs — Open Task Manager, go to the Startup tab, and disable programmes you don't need at startup.
• Full hard drive — Windows needs at least 15% free disk space to run smoothly. Delete unused files or move them to an external drive.
• Old or insufficient RAM — If your PC has less than 8GB RAM, upgrading can make a dramatic difference.
• Malware — Run a full scan with Windows Defender or Malwarebytes to rule this out.
• Overheating — Computers throttle their speed when hot. Clean the vents and ensure good airflow.

2. Blue Screen of Death (BSOD)

The dreaded blue screen usually indicates a serious hardware or software fault. Common causes include:

• Faulty RAM — Run the Windows Memory Diagnostic tool (search in Start menu)
• Corrupted system files — Run sfc /scannow in Command Prompt as Administrator
• Outdated or corrupt drivers — Update all drivers via Device Manager or your manufacturer's website
• Failing hard drive — Use CrystalDiskInfo to check your drive's health status

If the BSOD happens repeatedly, note the error code on screen and search it online. Each code points to a specific cause.

3. Laptop Won't Charge or Battery Dies Fast

Battery problems are very common in the UAE's hot climate. Here's how to troubleshoot:

• Check the charger and cable — Try a different charger or USB-C cable if possible
• Check the charging port — Look for dust, lint, or bent pins inside the port
• Recalibrate the battery — Drain it to 0%, then charge to 100% without interruption
• Update your BIOS and power drivers — Outdated firmware can cause charging issues

If the battery is more than 3 years old, it likely just needs replacing. This is a quick and affordable fix for most laptops.

4. No Internet or Very Slow Connection

Connectivity problems can stem from the computer or the network. To isolate the cause:

1. Check if other devices can connect to the same WiFi — if they can, the problem is your computer
2. Forget and reconnect to your WiFi network
3. Update your network adapter driver
4. Run the Windows Network Troubleshooter (right-click the network icon in the taskbar)
5. If using a cable, try a different Ethernet cable or port

5. Computer Overheating and Shutting Down

UAE summers push computers to their limits. Overheating causes slowdowns, crashes, and can permanently damage components. Here's what to do:

• Clean the vents and fans — Use compressed air to blow out dust from vents every 6 months
• Don't block airways — Never use a laptop on a bed or carpet; use a hard, flat surface
• Use a cooling pad — Especially important in summer months
• Replace thermal paste — If your laptop is 3–4 years old, the thermal paste on the CPU may have dried out
• Check running processes — A single misbehaving programme can peg your CPU at 100% and cause overheating

When Should You Call a Technician?

You should contact IT Geeks UAE if:

• You've tried the above steps and the problem persists
• Your computer is making unusual noises (clicking, grinding)
• You see error messages you don't understand
• Important files or data may be at risk
• The screen is cracked, the keyboard is unresponsive, or there's physical damage
