• Monitor functionality: Test the monitor with another computer or use another monitor with your computer to rule out display issues.

Update graphics drivers

Outdated or corrupted drivers can lead to several graphics-related issues. It's important to ensure that your graphics card drivers are up to date. There are two (2) ways of updating your graphics drivers: Download from the manufacturer's website or use Device Manager. To obtain the latest drivers, refer to the manufacturer's website first, and then use Device Manager as a secondary source.

Via the manufacturer’s website

You can download the latest drivers directly from the manufacturer’s website for more control over installation options. Keep in mind that manufacturers may release updated drivers after Microsoft releases its monthly updates.

Via Device Manager

1. Right-click on the Start button to bring up the Power User menu.
2. From the context menu that appears, left-click on Device Manager.
3. Left-click on Display adapters to expand it.
4. Right-click on your graphics card and select Properties.
5. Select the Driver tab and click Update Driver.

Roll back drivers

If problems started after a recent driver update, rolling back to a previous version might resolve the issue. To roll back a driver inside of Device Manager:

1. Right-click on the Start button to bring up the Power User menu.
2. From the context menu that appears, left-click on Device Manager.
3. Left-click on Display adapters to expand it.
4. Right-click on your graphics card and select Properties.
5. Select the Driver tab and click Roll Back Driver if the option is available.

Adjust graphics settings

Misconfigured graphics settings in your applications or Windows can sometimes lead to performance issues. To adjust settings:

• Apps: Open your game or application and access its graphics settings.
• Windows: Right-click on the Desktop and select Display settings.

Reduce the resolution and lower the graphics quality to see if performance improves.

Check for Windows Updates

Missing or pending Windows Updates can cause performance issues. Ensure you are running the latest version:

1. Left-click on the Start button to bring up the Start menu.
2. In the list of pinned apps on the Start menu, left-click on Settings (gear icon).
3. In the left-hand column, left-click on Windows Update.

Install any available updates, as they may contain critical fixes.

Test your GPU

Using a graphics card stress testing tool, you can test your graphics card and identify potential issues. This will help you determine whether the problem lies with the card or another component of your computer.

The Ultimate Boot CD (UBCD) is an excellent diagnostic tool that includes a video memory stress test. All you have to do is download the latest ISO file and burn it to a CD/DVD or use Rufus to create a bootable USB drive.

You may need to adjust some settings in your motherboard's BIOS to ensure the UBCD boots correctly. The UBCD is built on a Linux platform, so you may need to disable secure boot and UEFI boot features temporarily..

By methodically addressing potential issues, you can restore the functionality of your graphics card and enjoy all the graphics-intensive applications and games your system has to offer.

Every computer repair technician has a handful of software they regularly use to diagnose computer hardware issues. They are usually bootable drives and have their operating system included (FreeDOS or Linux). But carrying around all of these drives can be a nightmare. But luckily, there is a solution to this problem called the Ultimate Boot CD (UBCD).

The Ultimate Boot CD main menu

UBCD is a bootable disk image (ISO) containing the most complete computer hardware diagnostic tools I have ever seen. It includes diagnostic tools for testing BIOS, memory, and everything in between. It includes programs like Memteset86 and Windows Memory Diagnostics for testing memory and Data Lifeguard (Western Digital) and SeaTools (Seagate) for testing drives. In fact, it has an extensive collection of drive utilities.

All of the software inside the UBCD is non-commercial (freeware) and free to download. It comes as an ISO image from which you can create a bootable USB drive (see Rufus below) or burn it to a CD. You can even add more programs to it if you like. The UBCD is like the Swiss Army knife for computer hardware diagnostics.

Note: Some of the programs inside of the UBCD can render your drive unreadable or completely erase the data from it. The following is a list of the program categories inside of the UBCD. Please visit their website for a complete list of utilities included in the UBCD (see link below).

• BIOS (Basic Input Output System)
• CPU (Central Processing Unit)
• HDD (Hard Disk Drive)
• Boot Management
• Data Recovery
• Device Info and Management
• Diagnosis
• Disk Cloning
• Disk Editing
• Disk Wiping
• Installation
• Partition Management
• Memory
• Others
• Peripherals
• System

Now, for all of the Geeks out there, here's the technical information on the UBCD. The UBCD is formatted using the FAT (File Allocation Table) file system and operates one of two Linux boot loaders: SYSLINUX (default) or GRUB4DOS. From there, you can start either a Linux-based or DOS-based utility. UBCD is also customizable, so you can add any floppy or ISO image or FreeDOS-based application to it (see link below).

To boot your computer using the UBCD, you may have to change some settings in the BIOS. Turning off secure boot and enabling legacy boot options in the BIOS will ensure you can boot your computer on the UBCD.

The UBCD is a privately funded project, and donations are encouraged. Please donate if you find the UBCD as helpful as I do (see link below). For more information on the UBCD, follow the links below.
