How to Fix Windows Error - Graphics card not detected

Graphics is an important part of the Windows PC experience, especially when it comes to gaming, so it can be frustrating when the graphics card you spend hundreds of $ on isn't being detected. There can be several issues that are causing this and we'll walk you through all of them.

1. Graphics card is not enabled. In most cases, the "graphics card not detected" error can be resolved by simply enabling it manually. It's possible that your computer has automatically set a default display adapter and that all you need to do is change it. To do this, open Device Manager by pressing the Windows key + X and clicking 'Device Manager'.
Windows 10 Key X
Once you've opened Device Manager, navigate to 'Display Adapters' and click it. Under Display Adapters you will likely find your graphics card. Make sure it is enabled by clicking it and checking the black arrow at the top of Device Manager. If the arrow is pointing downwards, your graphics card is already enabled. If it isn't, click the arrow now and enable it.
Windows 10 Device Manager
2. Outdated drivers. Another common issue which may cause your graphics card to be undetectable is an outdated driver. If the card is visible under 'Display Adapters' on Device Manager, you can check for updates by clicking the green arrow at the top. If it isn't, you may have to visit your graphics card vendor's website and manually install their most recent software or update.

3. Driver not detecting graphics card. After ensuring your drivers are updated, if your computer is still failing to detect your graphics card, you can run a command which forces it to be detected by its drivers. Start by opening Command Prompt (type cmd in Windows search, right-click 'Command Prompt' and select 'Run as administrator')
Windows 10 Search CMD (Command Prompt)
On Command Prompt, type 'bcdedit /set pciexpress forcedisable' and hit Enter.
Windows 10 Command Prompt BDCEdit
After this operation completes, you can re-install your drivers, reboot, and test for errors.

4. Discrete graphics are disabled. If the solutions above didn't work for you, it's possible that "discrete graphics" are disabled. This means that your computer is forcing integrated graphics instead of accepting your card. You will need to access BIOS in order to fix this. The process for accessing BIOS depends on your computer but it usually involves pressing the Del key or F10 while rebooting. Once you're in BIOS, look for a 'dGPU' settings. This should be set to 'Enabled'.

Joker Malware - The Google Playstore Virus (Prevention and Removal)

Although Android malware is generally losing its grip on the Google Play store, as security is improved, there are still some prevalent strains which continue to cause chaos on infected devices. One example of this would be the "Joker" malware (also known simply as "Bread"), an infamous virus which first appeared on the Play store back in 2017. Recently, an improved version has made a comeback by hiding its payload in over 10 apps.

Android Joker Malware Graphic
How it Works: Joker managed to hide from Google Play's malware protection by disguising its malicious code in the form of 11 innocent-looking apps. Once installed, Joker activates through attacking URLs and signs the victim up to several seemingly random subscription services. It can do this in the background of its payload app while remaining completely invisible to the user. Joker takes advantage of certain non-accessible features on Android apps. The newest version of this virus obfuscates malware execution via several layers of URL payloads. This is why, despite numerous efforts to "secure" the Google Play Store, malware developers are able to push their code through antivirus into innocent looking apps.

Affected Apps: The following apps are currently known to be infected by the Joker malware (we will update this list accordingly - subscribe above to be notified)
  • All Good PDF Scanner
  • Mint Leaf Message - "Your Private Message"
  • Unique Keyboard - "Fancy Fonts & Free Emoticons"
  • Hummingbird PDF Converter - "Photo to PDF"
  • Tangram App Lock
  • Direct Messenger/Private SMS
  • Care Message/Part Message
  • Paper Doc Scanner/Blue Scanner/Meticulous Scanner
  • Desire Translate
  • Once Sentence Translator - "Multi-functional Translator"
  • Talent Photo Editor - Blur Focus
  • Style Photo Collage
  • com.hmvoice.friendsms
  • com.relax.relaxation.androidsms
  • com.remindme.alram
  • com.file.recovefiles
  • com.LPlocker.lockapps
  • com.peason.lovinglovemessage
  • com.cheery.message.sendsms
Prevention and Removal: If you have one of the apps listed above installed on your Android device, be sure to remove it immediately. Also, check your credit card charges for any suspicious subscription services or spammed orders. The Joker malware will likely adapt to stricter protections on the Google Play store in the future so be wary when installing brand new apps. Always check the reviews and research an app if your planning on getting it.

A Guide to IP Hopping on Windows 10 - The Cybersecurity Tactic That Never Fails

When it comes to maintaining cyber security on public networks, most Windows users tend to forget the fact that they are usually vulnerable. There are almost always new exploits hackers can use to force their way into your system. Although this doesn't always happen often, it's better to be safe than sorry. Unfortunately, when it comes to staying safe, antivirus programs can have flaws, and there is not a single app that is 100% secure. That being said, there are ways you can take advantage of network topology to ensure a safer public network experience. One of these ways is by switching across different local IP locations in a practice we call "IP hopping."
IP Hopping Graphic
IP hopping uses the structure of a network to prevent hackers and malicious programs from infiltrating your computer. By constantly switching to a new IP address, you become a very annoying target and much more difficult to track. On top of that, if a script is being installed onto your computer through a backdoor and you switch to a new address, it will have to follow you to your new network location in order to complete its operation. All in all, IP hopping is a very effective anti-hacking method that won't expire because it's based on an unchanging network topology.

Windows 10 Netstat View

So how can you perform this method on your own? Doing random IP jumps on your own is quite difficult without the use of third-party software, since you will have to rely on either Microsoft's automatic IP assigning algorithm or your own network scans to account for static locations that are taken or won't connect to the internet. Neither of these strategies are random and they won't be perfect when tested in the field. Fortunately, we have designed our own solution and implemented it in our cybersecurity toolkit Opticole. This software will allow you to make completely random hops on almost any network with a high success rate. Using its IP hopping feature is as easy as clicking a few buttons. Here is a video on making local IP jumps using Opticole:

Whether you decide to use this method or not, it will always be a much cheaper option than running antivirus which is also far more intrusive. Although antivirus is very important on its own, in the networking world, there are some rules every computer must follow. IP hopping takes advantage of these rules and allows you to avoid malicious encounters at a very low cost.

How To Fix The Windows 10 Start Menu Critical Error

Are you experiencing a Windows "Critical Error" which warns you that your Start Menu isn't working? This error often occurs after certain security updates and can be very bothersome. Luckily, there is an easy fix for this:

Updating. Have you updated your computer recently? This problem mainly occurs after an update, but it can also be a sign that you're missing one.

1. Start by pressing the Windows key + R to open the Run dialog. Then type 'cmd' and click Ok.
Windows 10 Run Command Prompt
2. Once you've opened Command Prompt, type 'wuauclt /detectnow /updatenow' and press Enter.
Windows 10 Update from Command Prompt

Creating a new Admin Account. If the problem persists after an update, you can try making an admin account on your computer. When you create a new user profile with an admin account, your Start Menu will typically begin working normally. This can be easily done through Task Manager:

1. Open Task Manager using the Ctrl + Shift + Esc shortcut or Ctrl + Alt + Delete -> Task Manager.

2. On Task Manager click File -> Run new task. Type 'net user [username] [password] /add'. Before clicking Ok, check the 'Create this task with administrative privileges' box.
Windows 10 NetUser Task Manager
3. Log out of the current account and log into the brand new net user. The Start Menu should now be operating correctly.

Restarting Application Identity Service. Since the Start Menu Critical Error could be connected to your Windows account, you can also try disconnecting it entirely from your computer's start-up process.

1. Open the run dialog by pressing the Windows key + R. Type 'services.msc' and click Ok.
Windows 10 Services
2. Double click on 'Application Identity'.
Windows 10 Services Application Identity
3. Set the Startup type to 'Automatic' and click 'Start'. Reboot.
Windows 10 Application Identity
4. If you're still getting a "Critical Error" open your Settings -> Accounts -> Sign-in Options -> Privacy and set 'Use my sign-in info to automatically finish setting up my device and reopen my apps after an update or restart' to Off.
Windows 10 Account Settings

Start Menu Troubleshooter. If nothing else works, you can always give the Windows 10 Start Menu Troubleshooter a try. Microsoft made this service available so that these errors can be fixed automatically.

Opticole - The Ultimate Privacy/Cybersecurity Toolkit for Windows - Overview

Opticole LogoOpticole is our brand new privacy/cybersecurity toolkit for Windows. Originally designed to protect users against Microsoft's privacy issues, it now includes a wide array of general-use cybersecurity features. Opticole can help defend against malicious payloads, remote access tools, and public network hackers. On top of that, it's lightweight and runs entirely off a single executable file.
Riserbo Opticole Screenshot

How it Works:
Opticole's privacy-protecting aspect can be demonstrated through its "Stealth-Mode" function. Stealth-Mode can be activated with the click of a single button. While enabled, Stealth-Mode allows Opticole to search through Windows privacy preferences and automatically set registry keys to increase your privacy. It also temporarily disables Cortana and other privacy-encroaching applications. Extra privacy can be attained with our file encryption tool which will encrypt any file or directory (Note: this feature shouldn't be used for critical files).

The port scanner available through Opticole is another great feature which will help you stay protected against malicious payloads or remote access tools. When clicked it will cross-reference active ports on your computer with ports known to forward dangerous processes. This "danger" port list is regularly updated. As soon as anything suspicious is found, Opticole will notify you by opening an HTML file displaying what it has discovered. Kill processes using suspicious ports by entering their port number in a textbox and pressing "Close Port".

Need a faster computer? Don't buy a new one, try Opticole's simple performance booster first. It's quick and edits graphics settings to enhance performance in the long-term. Along with all of these powerful tools, Opticole also implements a new exploit-evading technology known as IP hopping. This tactic allows a user to "hop" between local IP locations on most networks. In short, any hacker or threat on the network will have difficulty tracking your computer while it switches its IP address.

Opticole was released in May, and there are certainly more updates on the way. There is both a free version and a pro version currently available on our website here: Opticole
