Asus EeePC Tray Utility problem
Your video driver could have a problem with the installed one in your computer. It might be corrupted due to unexpected shut down or it could be virus related.
Solution 1: You can just reinstall the driver of your computer by running the CD which comes with the computer that says it is the Driver or you can download the video driver in the internet. Install the necessary driver for the video and then see if the problem still does exist.
Solution 2: Scan for viruses in your computer or if you don't have any anti virus software, purchase and install one first before you can scan your whole unit. If you want a free one download Microsoft Security Essentials and then install it. You need to have a genuine copy of your operating system though.
The file the system is telling about is the Display Switch utility which is bundled in your EeePC installation desk. With this file you are able to switch your display, from your EeePC to extended Display like Projectors. By pressing function plus the key, mostly Function+F2 you will be switch to the extended monitor or vice versa.
You can uninstall this utility. Look for the installation on the “Add and Remove Programs” of your operating system.
After removing, you can re-install the utility that comes in your bundled CD and I am sure that the message won’t show up again.
Actually, this utility is not necessary to have in your EeePC. Operating systems or even video drivers has these features.
You can switch your display even if without the said utility.
That error is from the EeePC Tray program. If you are not using it or it is not important, you can disable the tray program from running. Download the free version of CCleaner and install it. Once installed, start CCleaner then go to “Tools” on the left pane and select “Startup” on the right. In “Windows” tab, scroll down and locate the EeePC Tray application.
Select it then click “Disable”. Close CCleaner then restart the computer. See if this works. Also, try downloading EeePC ACPI Utilities. It offers targeted support for ASUS Eee PC. The project has been abandoned, though.
