### 12 Common Computer Problems and DIY Solutions
Computers can be tricky when they start acting up, but many issues can be resolved with a little troubleshooting. These problems can be related to both hardware and software, and often don’t require professional help. Before you rush to a repair shop, try these DIY solutions for common computer issues.
#### 1. **Computer Overheating**
**Problem:** Overheating is a frequent issue, especially with desktop PCs. If your computer feels hot to the touch or if you notice performance issues, it might be overheating.
**Solution:**
- **Check the Fans:** Open your PC case and ensure that the fans are working. Use a small brush to clean out dust from the fans and other components.
- **Reapply Thermal Paste:** If the CPU is getting too hot, reapply thermal paste between the CPU and the heat sink.
- **Improve Airflow:** Ensure your PC is not in an enclosed space. Place it on an elevated surface to allow proper air circulation and keep it clean.
#### 2. **Faulty USB Port**
**Problem:** If your USB ports aren’t working, the issue could be with the port itself or the connected device.
**Solution:**
- **Check the Cord:** Test the USB cord with another device to see if it’s the cord or the port that’s the problem.
- **Update Drivers:** Open Device Manager, right-click on your mouse or trackpad, select “Scan for hardware changes,” then uninstall and reinstall the USB controllers under “Universal Serial Bus controllers.”
- **Clean the Port:** Use a cotton bud to gently clean the USB port.
#### 3. **Slow PC**
**Problem:** A slow computer can be caused by too many apps running, lack of RAM, or a nearly full HDD.
**Solution:**
- **Close Unnecessary Apps:** Open Task Manager and close any apps that are using too much CPU.
- **Free Up Space:** Delete unused files and programs. For HDD users, consider deleting temporary files from the “Windows” folder.
- **Check for Malware:** Run a malware scan to ensure your system isn’t being slowed down by malicious software.
#### 4. **Blue Screen of Death (BSOD)**
**Problem:** The Blue Screen of Death can be alarming and is often caused by faulty hardware or drivers.
**Solution:**
- **Roll Back Updates:** If the issue started after a recent update, roll back the device driver or use System Restore.
- **Update Drivers:** Make sure your Windows OS and drivers are up to date.
- **Check for Malware:** Run a virus scan and free up hard drive space.
- **Event Viewer:** Check the system and application logs for clues about the cause of the BSOD.
#### 5. **Computer Won’t Turn On**
**Problem:** If your computer doesn’t power up, it could be due to external devices or power issues.
**Solution:**
- **Disconnect External Devices:** Unplug all external devices and try turning on your computer.
- **Check Power Source:** Plug your computer directly into a power outlet. If using a laptop, try removing the battery and running it on AC power.
- **Inspect Internal Components:** If the issue persists, you may need to check the motherboard and other internal components. Seek professional help if needed.
#### 6. **Desktop Keeps Restarting**
**Problem:** If your desktop keeps restarting, it could be due to overheating, low power supply, or system settings.
**Solution:**
- **Adjust Settings:** Go to Control Panel > System > Advanced System Settings. Under “Startup and Recovery,” uncheck “Automatically restart.”
- **Clean the Computer:** Regularly clean your computer components and ensure proper airflow.
#### 7. **Frozen Computer**
**Problem:** A frozen computer may be due to resource-heavy programs, insufficient disk space, or outdated drivers.
**Solution:**
- **Update Drivers:** Check for updates in Device Manager.
- **Check Power Supply:** Ensure your power supply is stable and well-regulated.
- **Update OS:** Consider updating or reinstalling your operating system if other solutions don’t work.
#### 8. **Keyboard Not Working**
**Problem:** If your keyboard stops working, it might be due to dust or a driver issue.
**Solution:**
- **Clean the Keyboard:** Remove dust and debris from the keyboard.
- **Update Drivers:** Go to Device Manager, select “Keyboard,” and update the driver.
- **Check Settings:** Go to Control Panel > Ease of Access and ensure “Filter Keys” is turned off.
#### 9. **Programs Not Responding**
**Problem:** Unresponsive programs may be due to software conflicts, resource shortages, or bugs.
**Solution:**
- **Install Updates:** Ensure all Windows updates are installed.
- **Defragment Disk:** Access disk properties and start defragmentation.
- **Increase Virtual Memory:** Go to Control Panel > System > Advanced System Settings, then increase virtual memory under the Performance section.
#### 10. **Browsers Not Working**
**Problem:** If your browser isn’t working properly, it might be due to outdated versions or corrupted cache.
**Solution:**
- **Clear Cache:** Clear the browser cache and cookies.
- **Update Browser:** Ensure your browser is up-to-date with the latest version.
#### 11. **Shutdown or Restart Issues**
**Problem:** Problems with shutdown or restart may be due to Windows features or BIOS settings.
**Solution:**
- **Use Command Prompt:** Type “shutdown /s /t /0” to force shutdown.
- **Check BIOS Settings:** Ensure CMOS and BIOS settings are correct. Use a recovery program if needed.
#### 12. **Internet Not Working**
**Problem:** If your internet isn’t working despite trying various fixes, it may be due to registry settings or network adapter issues.
**Solution:**
- **Edit Registry:** Open the registry editor and navigate to HKEY_LOCAL_MACHINE > SYSTEM > CURRENT_CONTROL_SET > SERVICES > NLASVC > PARAMETERS > INTERNET. Change “Enable Active Probing” from 0 to 1.
- **Update Network Adapter:** Uninstall and reinstall the network adapter driver from Device Manager.
