🚀 Top IT Support Problems & How to Solve Them Like a Pro

Working as a Senior IT Support Specialist, I’ve handled countless issues that disrupt business operations. Here are the most common problems and their solutions.

🔹 ❓ Why is my computer running slow?

• Check Task Manager (Ctrl + Shift + Esc) for high CPU/RAM usage
• Disable unnecessary startup apps (Task Manager > Startup tab)
• Clear temporary files (Win + R > type %temp% > Delete all files)
• Run SFC & DISM commands to check system integrity

  sfc /scannow
  dism /online /cleanup-image /restorehealth
  

🔹 ❓ Why can’t I connect to the company’s network?
– Restart the router/modem and your network adapter (Device Manager > Network Adapters > Disable & Re-enable)
– Run ipconfig /flushdns and netsh winsock reset in Command Prompt

ipconfig /flushdns
netsh winsock reset

– Check if the issue is VLAN or IP conflict-related

🔹 ❓ Why does my company’s email stop working suddenly?
– Verify Outlook settings (correct IMAP/POP3/Exchange configuration)
– Check if the issue is related to DNS, MX records, or SPF/DKIM settings
– Clear Outlook cache and restart

🔹 ❓ Why do users keep facing “Access Denied” errors on shared folders?
– Check NTFS permissions
