NOTE: Antivirus software can help protect your computer against viruses and other security threats. In most cases, you should not disable your
antivirus software. If you do have to temporarily disable it to install other software, you should re-enable it as soon as you're done. If you are
connected to the Internet or a network during the time your antivirus software is disabled, your computer is vulnerable to attacks.
**Step 2:**You may update your graphics card drivers and check if it helps.
Follow these steps to update the drivers:
- Open Device Manager by clicking the Start button, clicking Control Panel, clicking System and Security, and then, under System, clicking Device Manager.
If you're prompted for an administrator password or confirmation, type the password or provide confirmation.
- In the list of hardware categories, find display adapter, and then double-click the device name.
- Click the Driver tab, click Update Driver, and then follow the instructions. If you're prompted for an administrator password or confirmation, type the
password or provide confirmation.
