How to Troubleshoot Common Desktop Issues on a Budget Leave a comment
Introduction
When your desktop starts acting up, it’s tempting to panic or rush to a technician. But what if you could fix most problems yourself — without spending a fortune?
At Rollin Technologies, we know the average Nigerian desktop user faces issues like slow performance, freezing, power glitches, or poor internet connection. These problems can affect productivity, cost you money, or even make you feel like your device is useless.
The good news? Most of these desktop issues have quick, affordable fixes — and we’ll walk you through them.
In this guide, we’ll show you how to troubleshoot common desktop problems on a budget, so you can get back to work or school with confidence.
1. Slow Performance or Freezing? Try These First
Problem:
Your desktop is dragging, taking forever to open apps, or freezing mid-task.
Fix 1: Check and Close Background Apps
Open your Task Manager (Ctrl + Shift + Esc). Look under the “Processes” tab to see what’s consuming your memory and CPU. Applications like Chrome, Microsoft Teams, or large design software running in the background can slow things down. Right-click and select “End Task” for unnecessary apps.
Fix 2: Upgrade RAM or Switch to SSD
If your system has less than 4GB RAM or a mechanical hard drive (HDD), it’ll struggle with multitasking. RAM helps your system run smoothly, and SSDs significantly boost boot time and file access speed.
🛒 Shop budget-friendly RAM & SSDs at www.rollin.ng — we stock original parts that speed up any system.
Fix 3: Uninstall Unused Programs
Over time, you accumulate programs that take up storage and run in the background. Go to Control Panel > Programs and Features. Sort by size or installation date and remove anything you don’t need.
Fix 4: Clean Up Startup Programs
Some apps launch automatically and slow boot time. Press Ctrl + Shift + Esc > Startup tab, and disable non-essential items.
Fix 5: Run Disk Cleanup & Defragmentation
Go to File Explorer > Right-click your C: drive > Properties > Disk Cleanup. Delete temp files, recycle bin contents, and logs. Then go to Tools > Optimize and defragment your hard drive (if you’re not using SSD).
2. No Internet or Unstable Connection? Here’s What to Do
Problem:
You’re connected to Wi-Fi, but the internet isn’t working properly. Or your desktop doesn’t detect Wi-Fi at all.
Fix 1: Restart Your Router and Desktop
Start simple. Power off both devices and restart. This clears network congestion and resets the IP.
Fix 2: Use a USB Wi-Fi Adapter
Most desktops don’t come with built-in Wi-Fi. If yours doesn’t connect, it may need a USB Wi-Fi adapter — a plug-and-play fix.
🛒 Order an affordable adapter from Rollin Technologies and enjoy seamless wireless connection.
Fix 3: Check Network Driver Updates
Go to Device Manager > Network Adapters > Right-click your adapter > Update Driver. Also, reinstall the driver if needed.
Fix 4: Use Ethernet for Stability
Wi-Fi can be unreliable in shared spaces or during peak periods. If possible, connect via Ethernet for more stable performance.
Fix 5: Reset TCP/IP Stack
Open Command Prompt as Administrator and run these commands:
- netsh int ip reset
- ipconfig /release
- ipconfig /renew
- ipconfig /flushdns
This clears outdated settings and improves connectivity.
3. Display or Screen Not Showing Properly? Try This
Problem:
Your desktop turns on, but the screen is black. Or the display flickers, or resolution is off.
Fix 1: Check All Cable Connections
Ensure the VGA or HDMI cable is firmly connected to both the CPU and monitor. Make sure power is on and the monitor is set to the correct input source.
Fix 2: Replace the Display Cable
Loose, bent, or damaged cables often cause screen issues. Swapping to a new HDMI or VGA cable is an affordable fix.
🛒 Find quality display cables at unbeatable prices on www.rollin.ng.
Fix 3: Try a Different Monitor
Connect your CPU to another monitor. If it works, the old screen may need replacement.
Fix 4: Check Graphics Card Seating
If you have a dedicated graphics card, ensure it’s properly seated inside the CPU case. Over time, vibrations or dust can loosen it.
Fix 5: Update or Reinstall Graphics Drivers
Go to Device Manager > Display Adapters > Right-click > Update Driver. Use the manufacturer’s website for the latest driver.
4. No Power or Random Shutoffs? Let’s Fix That
Problem:
Your desktop won’t power on, or it randomly turns off during use.
Fix 1: Check Power Cable and Extension Box
Ensure your extension is working and the cable is tightly plugged in. Try plugging directly into a wall socket to rule out faulty extension.
Fix 2: Test With a UPS or Inverter
Nigeria’s power supply is unstable. Spikes can affect your power supply unit (PSU). Using a UPS protects your device and prevents sudden shutoffs.
🛒 Rollin Technologies offers affordable UPS and solar power backup kits — perfect for safe desktop usage.
Fix 3: Clean Dust From Vents and PSU Fan
Overheating due to blocked airflow can cause random shutdowns. Open the case (if you’re comfortable) and gently dust the components, especially the power supply fan.
Fix 4: Replace the Power Supply Unit (PSU)
If the PSU is faulty, your system may not turn on at all. You can buy a new PSU for less than buying a whole new desktop.
🛒 Affordable and reliable PSUs are available at Rollin.ng.
Fix 5: Run Hardware Diagnostics
If your system powers on briefly then goes off, use a bootable USB to run diagnostics. This helps check RAM, motherboard, and power issues.
5. USB Ports, Mouse or Keyboard Not Responding?
Problem:
You plug in your keyboard, mouse, or flash drive — but nothing works.
Fix 1: Restart the Computer
Temporary glitches happen. Restart your system and test again.
Fix 2: Try a Different Port
One USB port might be faulty. Try another. If none work, plug into a different system to verify it’s not the accessory that’s damaged.
Fix 3: Replace the Accessory
The issue may be with the keyboard, mouse, or cable — not your system. Low-quality accessories often fail early.
🛒 Rollin has budget-friendly replacement keyboards, wireless mice, and original cables in stock.
Fix 4: Update USB Drivers
Go to Device Manager > Universal Serial Bus Controllers > Right-click each and update driver. This may revive dead ports.
Fix 5: Disable USB Selective Suspend
This power-saving setting can deactivate USB ports. Go to Control Panel > Power Options > Change plan settings > Advanced > USB settings > Disable USB selective suspend.
