My laptop emachine g720 screen flickering


Laptop computers have LCD displays that are sensitive to many things. LCD displays have faults that sometimes produce a flickering screen, lines, dots or a faint display. These screens are sensitive to magnetic fields or electronic items near the computer. Speakers, cell phones, lights and other electrical items are examples. Your display also could be flickering due to software issues such as the video drivers or hardware issues relating to the inverter going bad or the LCD screen itself needing to be replaced. Trace the cause of your problem to come to a resolution.

1.Turn off the computer. Disconnect all external devices. Turn the computer over (bottom facing up). Take out the battery and reseat it. Turn the computer on.
2.Reset your resolution and refresh rate.
Windows XP:
Right click an open area on your desktop. Click "Properties" in the drop-down menu.
Click the "Advanced" button at the bottom of settings tab. Another dialog box appears. Click the "Monitor" tab. Change the Refresh rate to your default, or 60 hertz. Click "OK."
Windows Vista:
Click "Start, Control Panel." Find and click "Appearance and Personalization." Click "Adjust Screen Resolution." Change resolution to the default, or 800 x 600. Click "Advanced Settings." Click the "Monitor" tab. Change the refresh rate to the default, or 60 hertz. Click "OK."
Windows 7:
Click "Start, Control Panel." Find and click "Display" Click "Change display settings" on the left side. Change screen resolution to 800 x 600. Click "Advanced Settings" in the lower right. Click the "Monitor" tab. Change the refresh rate to 60 hertz. Click "OK."
3.Check the computer's surroundings. Move away any speakers, fluorescent lights, fans, cell phones, radios and any other electrical device that can cause flickering. Temporarily move electrical items away from the computer to see if they are producing this issue.
If the flicker stops, put back one item at a time to determine what is causing the problem.
4.Connect an external monitor to your laptop computer to see if that screen is also flickering. If there is no flicker, then the problem is strictly with the laptop, indicating a possible hardware failure. Contact the manufacturer for a replacement LCD.
If the flicker continues, go to next step.
5.Reset/Update your video driver. Click "Start" and right-click "My Computer." Click "Properties." The "System Properties" dialog box will appear.
6.Click "Device Manager." A list of items will appear. Click the (+) sign next to "Display Adapters."
7.Right-click the video adapter and click "Uninstall." Confirm removal. Restart the computer. The video driver will automatically reinstall itself.
8.Check to see if the flicker still exists. If so, go to the manufacturer's website. Download and install the newest video driver and BIOS for the computer.
9.Restart computer once drivers are installed. Continue to the next step if there is still flickering.
10.Open up your display screen all the way. If the flicker stops by opening it a certain distance, it is the display inverter. If the flicker still exists, the LCD screen should be replaced.
11.Contact the manufacturer of the computer for more information and a possible replacement inverter and LCD display. This will depend on the manufacturer and the computer itself.

I hope you find it very helpful. Thank you for using fixya.com

My laptop has trouble turning on straight away and sometimes it stops working when I am using it - the screen gets a funny looking design (?) on it.


try to do a disk check and scan your computer for viruses. Your system might have corrupted files in which it displays funny characters.

You have adware on your computer. It's very annoying and sometimes hard to get rid of. I recommend Malwarbytes for quick removals, www.malwarbytes.org.
Download it, update it, and run it. Also, while you're at it, remove any programs that aren't necessary or may have been one-time-use items in the past. Go to your Start button and then Control Panel. Once there go into add/remove programs and clear it out. Typically, removing any kind of browser addons can boost your system's performance.

good luck.

Computer display jumbled and unreadable


From what you describe, I'd suspect the Graphics processor, or even the motherboard as a source of the problem if the monitor works on a different system normally (Best way to check the monitor is a known good video source)

If it is the system, and the system is 8 years old, I'd recommend replacing the system rather than attempting to fix it. Trying to fix GOOD parts for an obsolete system is difficult at bst and oftern can be expensive. Often you can find a low end NEW system (One that is like 20 times faster than the failing system) for less than $300

Screen becomes jumbled when computer base is handled


It could possibly be the video card, I don't know that much about how hardware is laid out in that model, whether it is an built in card or a connected one so I cannot give you any trouble shooting tips. Do you still have tech support available with Gateway?
