When I first power up, display is OK. After short time, it pixilates, gets vertical bars, snow, shadows of mouse cursor all over the screen and eventually is so garbled it is unreadable. Backlight is always bright. Problem does not occur if I power-up in SAFE mode (tested several hours) but switching from NORMAL to SAFE mode without first powering down may carryover problem into SAFE mode. I tried disabling the 2 Radeon 9200 devices in Control Panel Device Manager. After cold power-up, it ran longer (10-15 min) in normal mode (with reduced display resolution) but started to eventually deteriorate in the same way. I have also updated display drivers, BIOS, and completely reinstalled the operating system using Gateway factory supplied DVD (this reverted to DirectX 9.0b from DirectX 9.0c that was recently installed). At one point, I suspected it is because of DirectX 9 but I could not find a way to revert back to DirectX 8.1 to see if this would solve the problem.

Computer users occasionally have a need to rotate, or "flip," a monitor display to be better able to read long documents or to view pictures. Because rotating a computer screen is such a basic function, modern operating systems (Windows XP and up) include hot keys and display options that enable the user to rotate the computer screen by 90, 180 and 270 degrees. Rotating the computer screen allows for more display options. For instance, when rotated 90 degrees, a 1680x1050 monitor becomes a 1050x1680 monitor, which provides more vertical pixels than a standard display.
Windows XP/Vista Monitor Orientation Minimize any windows or programs to the taskbar. Click the desktop. Press "CTRL" + "ALT" at the same time. Press one of the arrow keys to flip the monitor orientation by 90, 180 or 270 degrees. The left arrow rotates the computer screen 90 degrees; the down arrow rotates the computer screen 180 degrees; the right arrow rotates the computer screen 270 degrees; the up arrow resets the monitor orientation. Rotate the computer screen in Windows Vista by opening the Control Panel, searching for "Tablet PC" and changing the "Orientation" drop box to the desired rotation. b> Windows 7 Monitor Orientation b> Click the Start menu at the lower-left hand part of the screen, and open the Control Panel. Select "Display," then click "Change display settings" from the left column. When using multiple monitors, select the monitor that you would like to rotate. Click the drop box next to the "Orientation:" option. Select the desired rotation and click "Apply." Click "Keep Changes" or "Revert," depending on preference. Click "Apply" in the Display Settings window. Click "OK" to finish. Hope this helps
i would like to know how many and the kinds of beeps? there are what they call beep codes which indicates what kind of problem the your laptop is experiencing: here are the common ones:
0 beep = no power, loose card, short 1 short beep = normal,POST (Power On Self Test), your computer is ok 2 short beeps = POST error, review screen for error code. continuous beeps = no power, loose card, short repeating short beeps = no power, loose card, short 1 long, 1 short beeps = motherboard issue 1 long, 2 short beeps = video issue 1 long, 3 short beeps = video display circuitry three long beeps = keyboard/keyboard card error one beep, blank, incorrect display = video display circuitry
aside from the 1 short beeps, you need to take your laptop to a technician to have it looked at.
Once lines start appearing on the LCD its because the screen is starting to go bad on it, the pixels are starting to become defective. Only solution is to replace the screen or replace the monitor which would be cheaper.
No Power, Loose Card, or Short.
1 Short Beep
Normal POST, computer is ok.
2 Short Beep
POST error, review screen for error code.
No Power, Loose Card, or Short.
Repeating Short Beep
No Power, Loose Card, or Short.
One Long and one Short Beep
One Long and Two Short Beeps
Video (Mono/CGA Display Circuitry) issue.
One Long and Three Short Beeps.
Video (EGA) Display Circuitry.
Three Long Beeps
Keyboard / Keyboard card error.
One Beep, Blank or Incorrect Display
Video Display Circuitry.
tricky!! oh hi im Dyanne.. a totally unresponsive black screen can be th result of failure of th LCD or LCD inverter.( a specialized piece of electronics that energize th screen) to rule out th failure of th video display adapter or circuitry, try plugging in an external monitor..a standard pc monitor.. attached direct to th lappy. if it works, (as i susopect) th motherboard and video display are both working ok and its th LCD which is at fault. this can sometimes be repaired by a competent specialist. good luck xx
