HP Envy laptop black screen after BIO update

I have a habit of keeping my computer system as up-to-date as possible, including Windows updates and hardware drivers, so when I noticed there is a new version of BIOS for my HP Envy laptop the other day, I started the update process right away without giving much thought about the potential danger of updating the BIOS. The download of the BIOS update utility was smooth and the update process completed without interruption. Supposedly, the computer should reboot to finalize the BIOS update, but unfortunately my computer stuck with a black screen. The power button was lit but the computer did not respond […]


Selected boot image did not authenticate error after rolling back Windows Insider update

If you are in the Windows Insider Program and later on decided to opt out, you can choose to roll back to the last stable release you installed. However, the rollback may cause a very annoying error as show in the screenshot above: Selected boot image did not Authenticate. Press <Enter> to Continue. When you press <Enter>, you computer will shut down and the error repeats when you restart your computer. Based on my investigation, this seems to happen especially to HP computers, since my laptop is HP Envy, I got the exact error message after I tried to opt out […]


[Fixed] Computer slows down after Windows 10 Creators Update

[Note]: I have fixed my computer and now it is running fast. See the end of the post for the update and the possible fix(es) of the issue. I have a habit of keeping my computer up-to-date as much as I can, so whenever there is an update of either OS or software I will get on it and install it. This habit, however, is a double-edge sword, while most of the time it will protect me from getting hacked, it can cause trouble sometimes, which just happened to me recently: my computer became sluggish after I installed Windows 10 […]


GPS Spoofing is a big issue in Pokémon GO

GPS spoofing refers to changing a mobile device’s GPS location by using special GPS app without having to physically go to the new location. It has been widely used by Pokémon GO players yet Niantic has not done enough to prevent GPS spoofing. Besides the ability to fake device’s GPS location, some GPS spoofing apps also provide a “joystick” feature that enables Pokémon GO players to “walk” to virtually any location on earth without having to move their lazy butt, so they can “go” to any PokéStop to collect items, or “go” to a PokéGym to battle while sitting in a […]


Linux Mint running in software rendering mode on VirtualBox 2

In my previous posts, I introduced two Linux distros for new users: Zorin OS and elementary OS. Zorin OS provides a Windows-like interface and elementary OS provides a macOS-like interface, with the hope of making both Windows users and macOS users feel less intimidated when switching to Linux. According to the Linux distro watch, both Zorin OS and elementary OS are getting popular. In 2016, Zorin was ranked No. 7 while elementary was ranked No. 8, and in last 3 months (at the time of writing this post) both them are still in the top 10 ranking. However, if you […]

Players were excited about the new addition of the Pokémon family and were trying to catch the new Pokémon as soon as the […]


Zorin OS helps users to switch from Windows to Linux 2

I am not going to waste on explaining what Linux is, why/how to use it. You can Google it and you will find so much information online. Because Linux is open source and everyone can modify and contribute to it, there are many versions of Linux, and each version is called a Linux distribution, or distro in short. If you are not happy with Microsoft Windows OS but don’t want to switch to an expensive Apple computer, you can definitely give Linux a try. This being said, however, there are so many different Linux distros with different desktop environments (desktop […]

Regedit in Windows 10: error writing the value’s new contents

The Windows Registry is a critical and essential part of the Windows operating system and stores low-level settings for both the OS and the applications, such as device drivers, services, security settings, and so on. It is intended for advanced and experienced users to modify the system especially when there is no other way to do it,  because modifying Windows Registry may cause your Windows system not to operate and even crash. Therefore, normal users are not encouraged to touch the Windows Registry, and if they must, then it is highly recommended to backup the whole Windows Registry before any modification. […]
