Thank you for helping, but this still didn't fix the problem

IAN_FA,

Run the diagnostics on the lcd by following the information below. If there are no issues update the video card drivers from the link below.

Testing Devices using ePSA

• The ePSA starts running the quick test without waiting for user input.
• To select a specific device to test, users can tap the Esc key.

NOTE: The Touchpad/Mouse will be non–functional when the test is in progress. This is as per design.

The test reported that my monitor isn't working and that my CD drive isn't working.

Also, the screen flicker has gotten worse.
