How to fix Screen Flickering (Intel Graphic Cards)

Sometimes screen flickering can be a cause of an outdated driver. It sometimes also starts when we enable Hyper-V. On occasion, some Windows updates might even revert back to an older driver, and that can cause the flickering as well. Before calling tech support for hardware diagnosis, let's try to update the driver manually to the latest version first and see if that resolves the issue.

If you are on a laptop or branded PC, the manufacturer's software might tell you that you have the latest driver already installed. But that driver might already be outdated and you may need to go to the graphics card manufacturer to get the latest one.

Even after recognizing the graphics card hardware you may have, and download the latest driver from Intel, the manufacturer's software on your laptop or PC might stop you from installing it and receive the error below. Which is why we need to take a different approach and install it manually:
The error: The driver being installed is not validated for this computer. Please obtain the appropriate driver from the computer manufacturer.
  1. Right-click on This PC and click on Manage from the context menu.
  2. From the left side click on Device Manager.
  3. Expand the Display Adaptors list and right-click on your graphics adapter. Click on Properties from the context menu.
  4. If you cannot see a model number (for example, Intel HD Graphics 620), then navigate to the Details tab. From the drop-down menu, click on Hardware IDs. Right-click on the first ID on the list, and click Copy from the context menu.
  5. Paste and Search on a web browser to find out the model number of the graphics card. Now make a new search with that model number. 
  6. Make sure you enter the manufacturer's website. If your graphics card is Intel HD Graphics 620 for instance, then you need to enter the website.
  7. Make sure you check the date to get the latest version, as well as the appropriate operating system. Download the .ZIP file, not the .EXE file. The .EXE file after extracting the files will give you the above error message if you are on a laptop or branded PC (HP, Lenovo, Asus etc).
  8. Extract the files from the .ZIP file by right-clicking on it and clicking Extract All.
  9. Right-click on your graphics adapter in Device Manager, and click on Update driver.
  10. Click on Browse my computer for driver software.
  11. Click on Let me pick from a list of available drivers on my computer.
  12. Click on Have Disk.
  13. Click on Browse. Navigate to the location of your extracted drivers, and open the folder Graphics. Select the .INF file. Click Open.
  14. Click OK and click Next. Wait until the driver finishes installing.
  15. Right click on your graphics adapter in the Device Manager and click on Properties. Verify on the Driver tab that you have the latest driver installed.
If the screen flickering persists, then it could be a hardware issue and you might need to consult a technician.

New Page template button with timestamp in the title - Notion

These days I'm all about discovering ways for people to use Notion  without  the use of databases, as databases slow things down. I'm also an advocate for minimalism while still having an efficient workflow. Today I'm giving a tip with an example of daily journal entries. Usually, a Notion template comes with a database for journal pages, with a "Date created" property which is mighty convenient. But you can also replicate that without a database.  This will make it super fast for you to start journaling on a new page with the current date and time already added to the title. Create a simple text page where all your journal entries will be stored (no databases/tables). Optional: You may create a subpage to serve as an Archive for past entries. Again this should be a simple text page, not a database. You may also have multiple archives, named after the 12 months or years to keep things more organized. Type / , then template , then select the Template button . Give
