We have all been there. You are busy with something important, you need your computer to work, and suddenly it decides not to.
Maybe your laptop freezes right before a meeting. Maybe your emails stop sending when you need to reply to a client. Or maybe the printer only gives problems when you are already running late.
Computer problems are frustrating, but many of them have simple first steps you can try before calling IT support.
Here are seven common computer problems and what to do when they happen.
- Your Computer Is Running Slowly
You know when you open your laptop, click on Outlook, then wait… and wait… and wait? Then you try opening another program and suddenly everything feels even slower.
A slow computer can be caused by too many programs running, low storage space, outdated software, malware, or old hardware.
Try this:
Restart the computer, close programs you are not using, delete unnecessary files, and install any pending updates.
Call IT support if:
Your computer is still slow after the basics. Complete IT can check whether the device needs a clean-up, security check, upgrade, or replacement.
- The Internet or Wi-Fi Keeps Dropping
Nothing tests your patience like a video call freezing right when it is your turn to speak. Or when your cloud files stop loading and everyone starts asking, “Is the internet down?”
Wi-Fi issues can be caused by weak signal, old equipment, router problems, cabling issues, or internet service provider faults.
Try this:
Restart your router or access point. Check if other people in the office are having the same issue. Move closer to the Wi-Fi access point to see if the signal improves.
Call IT support if:
The issue keeps happening or certain areas of the office always have poor signal. Complete IT can review your Wi-Fi, network, cabling, switches, routers, and internet setup.
- Emails Are Not Sending or Receiving
There is nothing worse than typing an urgent email, hitting send, and then seeing it sitting in your outbox. Or waiting for an important client email that just does not arrive.
Email problems can be caused by internet issues, password changes, mailbox limits, Microsoft 365 problems, spam filtering, or security settings.
Try this:
Check your internet connection. See if the problem is only affecting you or everyone. Try logging into webmail to check if the issue is with Outlook.
Call IT support if:
Emails are bouncing back, multiple users are affected, or you suspect a security issue. Complete IT can help with Microsoft 365, mailbox issues, spam protection, and email security.
- Your Computer Freezes or Crashes
You are halfway through a quote, report, or presentation, and suddenly your screen freezes. You click everywhere, nothing happens, and now you are just staring at the screen hoping it comes back to life.
Freezing or crashing can be caused by software problems, overheating, viruses, updates, or failing hardware.
Try this:
Restart the computer, check for updates, and take note of when it happens. Also make sure the device is not overheating.
Call IT support if:
It keeps happening. Regular crashes can lead to data loss and may be a sign of a bigger hardware or software issue.
- You Cannot Access Files or Shared Folders
You need one document. Just one. But suddenly the shared folder will not open, OneDrive is not syncing, or you are told you do not have permission.
This can happen because of network issues, permission changes, sync problems, server issues, or missing files.
Try this:
Check that you are connected to the internet or office network. If you are working remotely, make sure your VPN is connected. If you use SharePoint or OneDrive, try opening the file through your browser.
Call IT support if:
Files are missing, permissions have changed, or more than one person cannot access the same folder. Complete IT can assist with Microsoft 365, SharePoint, OneDrive, server access, backups, and permissions.
- Pop-Ups, Suspicious Emails or Security Warnings
We have all seen those emails that look almost real. A fake invoice. A “payment update.” A banking detail change. Or a pop-up telling you your computer is infected and you must click immediately.
This is where you need to slow down. Cybercriminals rely on panic and urgency.
Try this:
Do not click suspicious links or open unexpected attachments. If someone asks you to change banking details, confirm it by phone using a number you already trust.
Call IT support if:
You clicked something suspicious, entered your password, downloaded a strange file, or keep seeing security warnings. Complete IT can help with cybersecurity, email protection, endpoint protection, firewalls, monitoring, and backups.
- The Printer Is Not Working
Printers have a special talent for failing at the exact moment you need them. The document is urgent, the client is waiting, and the printer simply says “offline.”
Printer issues can be caused by connection problems, paper jams, low toner, stuck print jobs, driver issues, or network changes.
Try this:
Check that the printer is on, connected, and has paper and toner. Restart the printer and your computer. Cancel any stuck print jobs and try again.
Call IT support if:
The printer keeps going offline or only some users can print. Complete IT can assist with printer setup, network printing, and troubleshooting.
