15 Common Computer Problems You Can Fix Yourself – Complete Troubleshooting Guide

15 Common Computer Problems You Can Fix Yourself – Complete Troubleshooting Guide


Computers are an essential part of our daily life, but technical problems can happen at any time. A slow PC, Wi-Fi connection problem, printer not responding, USB device not detected, or Windows/Ubuntu boot problem can interrupt your work.

The good news is that many common computer problems can be diagnosed and fixed without visiting a service center.

In this guide, CBR Drive explains 15 common computer problems and practical solutions that every Windows and Linux user should know.


1. Computer Is Running Very Slow

If your computer has become slow, first check which applications are consuming system resources.

Windows

Press:

Ctrl + Shift + Esc

to open Task Manager.

Check:

  • CPU usage

  • Memory usage

  • Disk usage

  • Startup applications

Disable unnecessary startup programs.

Ubuntu/Linux

Open Terminal and run:

top

or:

htop

If htop is not installed:

sudo apt install htop

Remove unnecessary applications and keep sufficient free disk space.


2. Wi-Fi Connected but Internet Is Not Working

First check whether the problem is with your computer or the network.

Try:

ping 8.8.8.8

If this works but websites don't open, the problem may be related to DNS.

You can also try:

ping google.com

If the first command works but the second fails, check your DNS configuration.

For Windows, restarting the network adapter and router can also resolve temporary connection problems.


3. Internet Is Very Slow

Check these things:

  1. Restart the router.

  2. Test another device.

  3. Move closer to the Wi-Fi access point.

  4. Check whether many devices are connected.

  5. Test using an Ethernet cable.

  6. Check your internet speed.

If only one computer is slow, the issue is probably local to that computer rather than the internet connection.


4. Printer Is Not Detected

If your printer is connected to the same LAN but cannot be detected:

Check the printer IP address

Print the printer's network configuration page.

Then test:

ping PRINTER-IP

Example:

ping 192.168.1.50

If there is no response, check:

  • Network cable/Wi-Fi

  • Printer network settings

  • Router connection

  • IP address

  • Firewall

For network printers, using a fixed/reserved IP address can make administration easier.


5. USB Pendrive Is Not Detected

Try the following:

  • Disconnect and reconnect the USB drive.

  • Try another USB port.

  • Test the drive on another computer.

  • Check Disk Management in Windows.

  • Check connected devices in Linux.

Ubuntu users can run:

lsusb

To check disks:

lsblk

If the device appears but has no mounted partition, the issue may be related to the filesystem or partition table.

Important: Do not format the drive before checking whether important data is stored on it.


6. Computer Does Not Boot

If the PC does not start:

Check the basics

  • Power cable

  • Monitor cable

  • Keyboard/mouse

  • RAM

  • Storage device

  • BIOS/UEFI settings

If you recently changed hardware, return the system to its previous configuration and test again.

For Windows systems, check whether the boot drive is visible in BIOS/UEFI.


7. Bootable USB Is Not Detected

If a Windows or Linux installation USB is not detected:

  1. Enter BIOS/UEFI.

  2. Check whether USB boot is enabled.

  3. Check Boot Order.

  4. Try another USB port.

  5. Recreate the bootable USB.

  6. Check UEFI/Legacy compatibility.

For modern systems, UEFI + GPT is generally the preferred configuration when supported by the operating system and hardware.


8. Windows Takes Too Long to Start

Open:

Task Manager → Startup Apps

Disable programs that don't need to start automatically.

Also check:

  • Available disk space

  • Windows updates

  • Background applications

  • Storage health

  • Malware/security scans

Avoid disabling Windows system components unless you know exactly what they do.


9. Ubuntu Is Running Out of Disk Space

Check available storage:

df -h

To find large directories:

du -h --max-depth=1 ~

You can also clean unused package files:

sudo apt autoremove

and:

sudo apt clean

Always check what will be removed before deleting important files manually.


10. Website Is Not Opening

If one website does not open, try:

  • Refreshing the page

  • Incognito/private mode

  • Another browser

  • Clearing browser cache

  • Restarting the network connection

  • Testing another device

If you see an error such as:

ERR_CONNECTION_TIMED_OUT

test another website first.

If every website fails, investigate the network connection rather than the individual website.


11. DNS Problems

DNS converts domain names such as:

google.com

into IP addresses.

Test DNS with:

nslookup google.com

or:

dig google.com

On Windows:

nslookup google.com

If DNS resolution fails while internet connectivity works by IP address, investigate the DNS configuration.


12. PC Cannot Connect to a Network Printer

A very common office problem is that one printer works while another printer on the same LAN cannot be added.

Check:

ping PRINTER-IP

If the printer responds, try adding it manually using its IP address.

Also check whether the printer and computer are actually on the same network/VLAN.

For offices with multiple access points, confirm that client isolation or wireless segmentation is not preventing communication.


13. System Becomes Slow After Installing Software

Recently installed software can sometimes introduce:

  • Background services

  • Startup programs

  • Browser extensions

  • High CPU usage

  • High memory usage

If the problem started immediately after an installation, uninstalling the recently added software can be a useful diagnostic step.


14. How to Quickly Check Your PC's IP Address

Windows

Open Command Prompt:

ipconfig

Look for:

IPv4 Address

Ubuntu/Linux

Run:

ip addr

or:

hostname -I

This is one of the most useful commands for troubleshooting LAN and printer problems.


15. The Most Important Troubleshooting Rule

When troubleshooting a computer problem, don't change many things at once.

Use this simple process:

Identify → Test → Isolate → Fix → Verify

For example:

Internet not working

→ Test another device
→ Test the router
→ Test the computer
→ Test IP connectivity
→ Test DNS
→ Identify the failing component
→ Apply the fix
→ Test again

This approach prevents unnecessary changes and makes technical problems much easier to solve.

Final Thoughts

You don't need to be an IT expert to solve many everyday computer problems.

Learning a few basic commands, understanding IP addresses, checking hardware connections, and following a systematic troubleshooting process can save significant time.

Whether you use Windows, Ubuntu, or another operating system, the most important skill is not memorizing hundreds of commands—it is learning how to identify the problem step by step.

मदन लाल ढींगरा

 

मदन लाल ढींगरा












मदन लाल ढींगरा (18 सितंबर 1883 - 17 अगस्त 1909) 

एक भारतीय क्रांतिकारी थे |

निधन: 17 अगस्त 1909 (आयु 25 वर्ष); लंदन

संगठन: इंडिया हाउस

जन्म: 18 सितंबर 1883; अमृतसर, पंजाब

आंदोलन: भारतीय स्वतंत्रता आंदोलन


भारतीय स्वतन्त्रता संग्राम के अप्रतिम क्रान्तिकारी थे। भारतीय स्वतंत्रता की चिनगारी को अग्नि में बदलने का श्रेय महान शहीद मदन लाल धींगरा को ही जाता है । भले ही मदन लाल ढींगरा के परिवार में राष्ट्रभक्ति की कोई ऐसी परंपरा नहीं थी किंतु वह खुद से ही देश भक्ति के रंग में रंगे गए थे । वे इंग्लैण्ड में अध्ययन कर रहे थे जहाँ उन्होने विलियम हट कर्जन वायली नामक एक ब्रिटिश अधिकारी की गोली मारकर हत्या कर दी। कर्जन वायली की हत्या के आरोप में उन पर 22 जुलाई, 1909 का अभियोग चलाया गया । मदन लाल ढींगरा ने अदालत में खुले शब्दों में कहा कि "मुझे गर्व है कि मैं अपना जीवन समर्पित कर रहा हूं।" यह घटना बीसवीं शताब्दी में भारतीय स्वतन्त्रता आन्दोलन की कुछेक प्रथम घटनाओं में से एक है।


आरम्भिक जीवन

    मदनलाल धींगड़ा का जन्म १८ सितम्बर सन् १८८३ को पंजाब प्रान्त के एक सम्पन्न हिन्दू परिवार में हुआ था। उनके पिता दित्तामल जी सिविल सर्जन थे और अंग्रेजी रंग में पूरी तरह रंगे हुए थे किन्तु माताजी अत्यन्त धार्मिक एवं भारतीय संस्कारों से परिपूर्ण महिला थीं। उनका परिवार अंग्रेजों का विश्वासपात्र था और जब मदनलाल को भारतीय स्वतन्त्रता सम्बन्धी क्रान्ति के आरोप में लाहौर के एक कालेज से निकाल दिया गया तो परिवार ने मदनलाल से नाता तोड़ लिया। मदनलाल को जीवन यापन के लिये पहले एक क्लर्क के रूप में, फिर एक तांगा-चालक के रूप में और अन्त में एक कारखाने में श्रमिक के रूप में काम करना पड़ा। कारखाने में श्रमिकों की दशा सुधारने हेतु उन्होने यूनियन (संघ) बनाने की कोशिश की किन्तु वहाँ से भी उन्हें निकाल दिया गया। कुछ दिन उन्होंने मुम्बई में काम किया फिर अपनी बड़े भाई की सलाह पर सन् १९०६ में उच्च शिक्षा प्राप्त करने इंग्लैण्ड चले गये जहाँ उन्होंने यूनिवर्सिटी कालेज लन्दन में यांत्रिकी अभियांत्रिकी में प्रवेश ले लिया। विदेश में रहकर अध्ययन करने के लिये उन्हें उनके बड़े भाई ने तो सहायता दी ही, इंग्लैण्ड में रह रहे कुछ राष्ट्रवादी कार्यकर्ताओं से भी आर्थिक मदद मिली थी।


सावरकर के सान्निध्य में

    लन्दन में धींगड़ा भारत के प्रख्यात राष्ट्रवादी विनायक दामोदर सावरकर एवं श्यामजी कृष्ण वर्मा के सम्पर्क में आये। वे लोग धींगड़ा की प्रचण्ड देशभक्ति से बहुत प्रभावित हुए। ऐसा विश्वास किया जाता है कि सावरकर ने ही मदनलाल को अभिनव भारत नामक क्रान्तिकारी संस्था का सदस्य बनाया और हथियार चलाने का प्रशिक्षण दिया। मदनलाल धींगड़ा इण्डिया हाउस में रहते थे जो उन दिनों भारतीय विद्यार्थियों के राजनैतिक क्रियाकलापों का केन्द्र हुआ करता था। ये लोग उस समय खुदीराम बोस, कन्हाई लाल दत्त, सतिन्दर पाल और काशी राम जैसे क्रान्तिकारियों को मृत्युदण्ड दिये जाने से बहुत क्रोधित थे। कई इतिहासकार मानते हैं कि इन्ही घटनाओं ने सावरकर और धींगड़ा को सीधे बदला लेने के लिये विवश किया।


कर्जन वायली का वध

    १ जुलाई सन् १९०९ की शाम को इण्डियन नेशनल ऐसोसिएशन के वार्षिकोत्सव में भाग लेने के लिये भारी संख्या में भारतीय और अंग्रेज इकठे हुए। जैसे ही भारत सचिव के राजनीतिक सलाहकार सर विलियम हट कर्जन वायली अपनी पत्नी के साथ हाल में घुसे, ढींगरा ने उनके चेहरे पर पाँच गोलियाँ दागी; इसमें से चार सही निशाने पर लगीं। उसके बाद धींगड़ा ने अपने पिस्तौल से स्वयं को भी गोली मारनी चाही किन्तु उन्हें पकड़ लिया गया।


अभियोग

    २३ जुलाई १९०९ को धींगड़ा मामले की सुनवाई पुराने बेली कोर्ट में हुई। अदालत ने उन्हें मृत्युदण्ड का आदेश दिया और १७ अगस्त सन् १९०९ को लन्दन की पेंटविले जेल में फाँसी पर लटका कर उनकी जीवन लीला समाप्त कर दी। मदनलाल मर कर भी अमर हो गये।


स्मारक

इनका स्मारक अजमेर में रेलवे स्टेशन के ठीक सामने है।
