Question 1

Why is my internet connection so slow?

Accepted Answer

Slow internet can be caused by bandwidth congestion, poor router placement, outdated equipment, background updates, or wireless interference. Restart your modem and router, run a speed test, scan for malware, update network drivers, and check if the issue affects multiple devices. Use a wired Ethernet connection for critical tasks when possible.

Question 2

How do I fix "No Internet Access" error?

Accepted Answer

Run the Network Troubleshooter, release and renew your IP with ipconfig /release and ipconfig /renew, flush DNS with ipconfig /flushdns, and reset the network stack with netsh winsock reset and netsh int ip reset. Also update adapter drivers, check MAC filtering on the router, and temporarily disable firewall or antivirus to test.

Question 3

Why does Wi-Fi keep disconnecting?

Accepted Answer

Intermittent disconnections usually come from signal interference, driver issues, power management settings, or router overload. Move the router away from cordless phones and microwaves, update wireless drivers, disable power-saving on the adapter, change Wi-Fi channel, update router firmware, and enable band steering if available.

Question 4

Computer won't turn on — what to do?

Accepted Answer

Check the power cable and outlet, listen for PSU fan noise or burnt smells, and listen for motherboard beep codes or LED indicators. Reseat RAM and the graphics card, or clear CMOS by removing the battery for five minutes. Always unplug the computer and ground yourself before touching internal components.

Question 5

How to fix Blue Screen of Death (BSOD)?

Accepted Answer

Note the error code, boot in Safe Mode, run Windows Memory Diagnostic, check the disk with chkdsk /f, update graphics and network drivers, and use System Restore to a previous working state. Common causes include driver issues, hardware failure, software conflicts, and corrupted system files.

Question 6

Computer overheating — how to fix?

Accepted Answer

Shut down and let the system cool, confirm fans are spinning, improve ventilation, clean dust from fans and heatsinks, reapply thermal paste every two to three years, and improve airflow. Healthy temperature ranges are roughly CPU idle 30–40°C, CPU load 60–80°C, and GPU load 65–85°C.

Question 7

Application keeps crashing — how to fix?

Accepted Answer

Update the app, reinstall it, run as administrator, or use compatibility mode. Check Event Viewer logs, update DirectX and Visual C++ Redistributables, temporarily disable antivirus, run sfc /scannow, or perform a clean boot to isolate software conflicts.

Question 8

Windows update stuck or failing?

Accepted Answer

If an update is stuck for more than two hours, run the Windows Update Troubleshooter and clear the update cache by stopping wuauserv, cryptSvc, bits, and msiserver, renaming SoftwareDistribution and catroot2 folders, then restarting the services. Download and install the update manually from the Microsoft Update Catalog if needed.

Question 9

How to remove a virus/malware?

Accepted Answer

Disconnect from the internet, boot in Safe Mode with Networking, run a full antivirus scan, use specialized tools such as AdwCleaner or HitmanPro, remove suspicious browser extensions, clear temp files, and reset browsers to default. If ransomware hits, restore from backups instead of paying the ransom.

Question 10

How to prevent ransomware attacks?

Accepted Answer

Follow the 3-2-1 backup rule, use email filtering and prompt patch management, apply least-privilege access, disable risky Office macros, block RDP from the internet, segment your network, and train staff to recognize phishing emails and report suspicious activity.

Question 11

Server not responding — how to troubleshoot?

Accepted Answer

Check physical power and cabling, ping the server IP, verify firewall rules and DNS, inspect CPU memory disk and I/O usage, confirm required services are running, review event logs, and use out-of-band management such as iDRAC or iLO if remote access is unavailable.

Question 12

Database connection errors — how to fix?

Accepted Answer

Confirm the database service is running, verify the connection string and credentials, check DNS and firewall port access, increase timeout values if needed, and investigate account lockouts or authentication mode mismatches.

Question 13

Can't send or receive emails — what to do?

Accepted Answer

Verify internet access, confirm incoming POP3 or IMAP and outgoing SMTP settings, check port numbers and SSL or TLS configuration, ensure outgoing authentication is enabled, confirm mailbox storage is not full, and review spam filters and mailbox rules.

Question 14

Emails going to spam — how to fix?

Accepted Answer

Configure SPF, DKIM, and DMARC records correctly, avoid spam trigger words and all-caps subject lines, include a plain-text version, check IP reputation, warm up new IPs gradually, monitor bounce rates, and process unsubscribes promptly.
