Here are several methods to improve the speed and performance of Windows 10. Read More aren’t foreign experiences to most Windows users. But when these occur, are you quick to blame Windows itself for these problems?


The truth is that the Windows operating system (OS) isn’t really responsible for many of these issues. Oftentimes, a new piece of hardware, buggy software, or even user neglect are the cause — not Windows. If you want to up your Windows knowledge and learn basic troubleshooting, read on to see why these issues occur and what they signal.

1. Blue Screens of Death

Everyone knows what a blue screen of death (BSOD) is. It’s been popularized from years of jokes. But do you know what a blue screen actually signifies?

What we call the BSOD is an OS stop error. This means that Windows ran into a problem that it couldn’t handle Don't Panic! Everything You Need To Know About Kernel Panics If you’ve used a computer, you will have no doubt encountered the Blue Screen of Death, or a kernel panic, where the machine restarts without warning, costing you all your work. Read More and had to shut down to avoid damage to the system. Just from this, it’s clear that blue screens aren’t always Windows’ fault.

Sometimes this is the case, as it was with the core changes in Windows Vista that made it more susceptible to crashing thanks to hardware issues. But usually, you can trace the problem to a new piece of hardware or failing internal component.

Whenever you see a blue screen, don’t immediately restart your computer. Look for the error code: this will give you vital information about what caused the problem. In the below example of a Windows 8 and newer BSOD, we can see the HAL_INITIALIZATION_FAILED code. After a restart, Googling this will give more information about the specific problem. You can also use the BlueScreenView tool to analyze blue screens after the fact.

In this case, it seems that this particular error happens when Windows is having problems waking up from sleep or runs into an issue with virtual machines. This cuts your troubleshooting down immensely.

We will show you how to fix this stop code. Read More isn’t usually a big deal. Occasionally, Windows will run into a small error that never pops up again. You shouldn’t worry about troubleshooting these errors unless they occur regularly.

See how some thinking can turn a confusing error into actionable intel? That’s troubleshooting theory, and it applies to more than just BSODs. You can also apply these ideas when you encounter…


Common error codes and how to fix them:

2. Safe Mode

Have you ever seen Windows boot into Safe Mode How to Boot in Safe Mode on Windows 10 Facing Windows booting problems? Safe Mode is a built-in Windows 10 troubleshooting feature you should try first. Read More on its own, or wondered what the term means? Safe Mode allows Windows to boot into a stripped-down environment so you can better troubleshoot it.

During normal PC startup, Windows loads drivers for your graphics card, sound, and all the fancy effects of the OS. While these are certainly pleasant features to have, they aren’t vital for Windows functioning.

Thus, in Safe Mode, your display resolution reduces to 640 x 480, disables sound, does not run startup programs, and disconnects non-vital devices (your keyboard and mouse still work). This comes in handy for several troubleshooting functions:


When Windows is stable in Safe Mode but has issues when normally booting, something present is causing an issue. You should try uninstalling recently installed software and removing new hardware to see if they are the source of the crashing.

3. Internet Connection Problems

Everyone hates internet connection issues.

Read More to get an idea of how they act under pressure.

Like other items discussed so far, network problems are almost never the fault of Windows. Rather, they typically arise from your internet service provider’s (ISP) problems or a router hangup. We’ve covered the complete process for troubleshooting and diagnosing network problems, so we’ll offer a few thoughts on general troubleshooting here.

Troubleshooting theory applies quite well to network issues. Start with the element of the connection closest to what you know is working. It’s a waste of time to try diagnosing your router settings when you haven’t even confirmed that Windows is properly connecting to the router How to Fix Your Wireless Internet Connection in Windows Are you struggling to get a strong and stable wireless Internet connection? It could be the hardware or Windows itself causing the problem. Here are some troubleshooting tips. Read More . If you can’t connect to the internet with your smartphone either, it’s not just a problem on your PC.


In this case, you would proceed to check if your router is live. If you confirmed it was working properly, you could then place a call to your ISP to see if they’re experiencing outages in your area. As you can see, working your way up the chain lets you confirm what exactly is failing to connect. It’s not a requirement that you’re a network engineer to diagnose where a connection is getting stuck.

4. Hardware Failures

While you can’t see the components that make up your computer, with a bit of knowledge you can figure out which of them are going bad. Often, RAM failing 5 Signs and Symptoms That Your RAM Is About to Fail If you're having computer problems and you can't pinpoint the cause, faulty RAM may be the cause.

This is an extremely... Read More . Of course, hardware problems aren’t the fault of Windows — components in a machine can fail regardless of the OS.

You can apply some wisdom here when your computer won’t boot, too. For example, consider a situation where your computer turns on, but won’t boot into Windows. If your BIOS greets you with a message that no OS is detected, you can remember that the hard drive is where Windows and all of your files live. When the computer can’t access Windows, it’s likely because the hard drive is dead.

Other symptoms can indicate similar problems with components. If you suddenly can’t see anything on your laptop screen but hooking it up to an external monitor works fine, you may have a loose hinge or dying screen. But if you try to turn your computer on and get a blank screen that won’t recognize an external monitor, you could have a dead motherboard 3 Troubleshooting Tips Guaranteed to Boot Your PC's Motherboard This article covers basic motherboard troubleshooting methods, common faults and anti-consumer friendly return policies, if all goes wrong. Read More . Think about what you’re seeing and what that proves. If you see the BIOS, your motherboard isn’t dead because nothing would load if that was the case.

Another example: if Windows seems to forget the correct time Your Windows 10 Time Is Wrong? Here's How to Fix the Clock When your Windows 10 time is wrong or keeps changing, the fix could be easy. Don't let your computer clock go wrong again. Read More , this isn’t actually an issue with Windows.

5. Malware

While Windows is more susceptible to malware than other OSes, it shouldn’t get the blame for the effects of malware on your system. After all, Windows 10 is packed with more security features than ever before. Combined with some common sense, most users shouldn’t have to deal with malware again.

If you encounter rogue software, you should still know its behavior and how to remove it. Strange pop-ups, extremely slow performance, and toolbars and other garbage appearing in your browser are all signs of malware infection. Once you have a hunch your computer is infected, you should browse the Programs and Features list for anything you don’t trust and remove it The Complete Malware Removal Guide Malware is everywhere these days, and eradicating malware from your system is a lengthy process, requiring guidance.

    I recently tried to reset my HP laptop. I kept getting the stop error "System PTE Misuse". After chatting with MS a bit (and getting nowhere) I found that it was actually a bios update. Updated the bios and everything worked like a champ.
