Computer Hardware Issues: Can I Fix My Computer?

It’s often best to leave the computer hardware repair to IT professionals who have the training and expertise to fix complex problems. However, some common hardware issues have simple fixes that could save your small or midsized business (SMB) time and money.

What Can Go Wrong If You Don’t Take on Basic Troubleshooting?

Before getting into the fixes, it’s worth taking a few minutes to understand what can go wrong if you ignore minor problems or less than peak performance.

Decreased Performance

• Slow boot times, laggy applications or freezes
• Temporary glitches

Data Loss

• Ignoring system crashes or disk errors could lead to file corruption or loss of data

System Instability

• Minor software conflicts or malware, if left unresolved, can cause frequent crashes

Security Risks

• Outdated software or strange system behavior could leave your system vulnerable to viruses, malware or unauthorized access from cybercriminals

Costly Repairs Later

• Minor, fixable issues might escalate into a costly repair
• Ignoring hardware warnings can result in permanent damage

Wasted Time

• A glitchy system causes delays, lost work and repeated crashes

Harder Diagnosis Later

• Ignoring small problems makes it harder to identify the root cause later

Increased Frustration & Stress

• A malfunctioning system can lead to frustration, lower productivity and burnout

Taking 10 to 15 minutes to do basic troubleshooting can often prevent hours of future hassle and protect your system’s health.

Q: How can I tell if my RAM is causing computer problems?

A: Common signs of faulty RAM include random crashes, blue screen errors (BSOD), programs freezing, or your system failing to boot properly. If you're experiencing these issues, you can test your RAM using built-in or third-party diagnostic tools.

What Are Basic Troubleshooting Tips I Can Try if I Want to Fix My Computer?

However, some common hardware issues have simple fixes that could save your small or midsized business (SMB) time and money:

• Computer Won’t Boot Up – This most basic hardware issue often results from a faulty power supply. First, check to see if the power cord is seated correctly at both the outlet on the back of the CPU and the wall outlet or power strip. If both ends appear to be plugged in properly, test the power outlet with another device to make sure it’s functioning
• Windows Doesn’t Start Up – If Windows repeatedly won’t boot up, you might have to reinstall Windows from a Windows recovery disk
• Blank Screen – If you have a blank screen after booting up, check the connection (wireless or wired) between the CPU and your monitor. If you determine that it is not a connection issue and you are confident your monitor is working, you might need to consult IT professionals
• Frozen Screen – A frozen computer usually needs a restart. Unfortunately, you’ll lose unsaved work in the process. There are several common causes of a frozen computer:
  • Spyware – Hidden spyware installed by hackers can cause a freeze
  • Insufficient RAM – Robust programs require high amounts of RAM to continue functioning smoothly
  • Corrupt or Missing Files – Corrupt or missing files often cause freezes by disrupting operations
  • Registry Conflicts – Registry errors usually arise from improperly uninstalled applications or too many unused files that come into conflict during boot-ups
• Overheating – Improper cooling or malfunctioning internal fans will cause overheating. Sleeping or shutting down for a time will fix the issue, but if overheating recurs frequently, consult IT experts to repair the problem and remove dust from the computer
• Operating System or Software Malfunctions – An unresponsive system or software application could indicate a virus. Address it by shutting down, then rebooting and running a virus scan
• Slow Computer – There are several causes of a slow computer.
  • Shortage of RAM – Shut down non-essential programs or add RAM
  • Viruses and other malware – Run regular anti-virus scans
• Unusual Noise – Unexpected noise from your computer could indicate a failing hard drive or fan. If your hard drive is causing the noise, that’s a serious computer hardware repair issue, and IT professionals should address the problem before your data is compromised. Regularly backing up data will likely eliminate the potential for permanent data loss (data can often be transferred from a failing machine, but not always from one that is non-functional)
• Slow Internet Connection – For slow browsing issues, try clearing cookies, internet history and temporary files from your computer. Removing these files will usually make your browser more efficient, thus speeding up your connection. Rebooting your router might also help correct speed issues. If you have a wired connection, check all cables and plugs for problems.

Q: What should I do if I want to fix my computer myself?

A: If your computer is acting up—slow, unresponsive, crashing or behaving strangely—there are several basic troubleshooting steps you can try: reboot, check connections, close unneeded applications, update to the latest version of your operating system, run a virus check and free up disk space.

Unfortunately, most small to midsized businesses have neither the time nor the expertise to analyze and repair computer hardware issues on their own. In addition, tasks such as installing a hard drive and other comprehensive computer hardware repair can be confusing and, to many, daunting. For such functions, contact a professional IT consulting services that specialize in SMBs. The IT experts can also ensure that you maintain compatibility, security protections and other protocols to safeguard your hard-earned data systemwide.

If your IT technician indicates it is time for a replacement computer, ask them for recommendations for your specific needs. They can provide suggestions for a new device that will be compatible with your existing system and meet productivity needs without overspending on features you may not use. (Some service providers have access to manufacturer discounts, too.) They can also quickly set it up and explain any new features. One final task when replacing old tech devices is to ensure all business data is securely removed before recycling, storing or donating old equipment.
