Introduction
Computers rarely slow down for no reason.
Most performance problems come from a small number of issues:
• Too many startup programs
• Malware or unwanted software
• Full storage drives
• Failing updates
• Background processes consuming resources
This 10-minute PC Health Check helps you quickly identify the most common causes of computer problems.
If you discover issues you cannot resolve, Fortify Remote Tech Support can perform a secure remote diagnostic session.
Step 1 — Check Startup Programs
Too many startup applications are one of the most common causes of slow computers.
How to Check
Press:
CTRL + SHIFT + ESC
Open the Startup tab.
Look for programs marked High Impact.
Examples:
• Game launchers
• Adobe updaters
• Messaging apps
• Old printer software
Disable anything unnecessary.
Restart your computer afterward.
Step 2 — Check Storage Space
Computers perform poorly when the drive is almost full.
Check Drive Usage
Open:
This PC
Look at the C: drive.
If storage is above 85% full, performance problems often appear.
Common fixes:
• Delete large files
• Remove unused programs
• Empty recycle bin
Step 3 — Scan for Malware
Malware is one of the most frequent causes of:
• slow computers
• browser popups
• random system errors
Run a quick scan using:
Windows Security
Virus & Threat Protection
Quick Scan
If threats appear, follow removal instructions.
Step 4 — Check System Updates
Broken updates can cause instability.
Open:
Settings
Windows Update
Check for:
• updates stuck installing
• repeated failed updates
Restart the computer if updates are pending.
Step 5 — Check Background CPU Usage
High CPU usage indicates software problems.
Open Task Manager again.
Look at the Processes tab.
If CPU usage remains above 50% while idle, something may be misbehaving.
Examples include:
• browser extensions
• software updaters
• malware
Step 6 — Check WiFi Performance
Slow internet often feels like a slow computer.
Run a speed test:
speedtest.net
Compare results with your expected internet speed.
If speeds are far lower, the issue may be:
• router configuration
• WiFi interference
• network congestion
Step 7 — Check System Temperature
Overheating computers slow themselves down to prevent damage.
Signs include:
• loud fans
• hot laptop chassis
• sudden performance drops
Dust buildup inside laptops and desktops is a common cause.
When DIY Fixes Are Not Enough
Some problems require deeper diagnostics.
These include:
• hidden malware
• driver conflicts
• system corruption
• network configuration issues
Fortify Remote Tech Support can perform a secure remote diagnostic session to investigate these problems.
Request a Remote Diagnostic
If your computer still feels slow or unstable, Fortify can analyze your system live and identify the root cause.
Remote diagnostics can help resolve:
• slow computers
• malware infections
• network issues
• Windows errors
