My dell has issues with the graphics display,at times when i switch it on it just shows a blank greyish black screen,at other times when it works normally it will just start having a background like a tv static screen with background having a purplish colourmaking it difficult to read any text on the screen and displays pictures and videos with a purplish smear to everything,it goes from that to normal and bad inthe course of any use. I recently changed the vga card and it was normal for 2 weeks before starting to act up again,please how can i hve a permanent fix to this problem?

Sounds like the real problem is with the CCFL lamp to me. :(

SOURCE: graphics card failure

the error: (Under this test, results show Error code 5300: 0119, which different comments for different parameters) Msg: Detected a failure while writing and reading video memory. (e.g.) Video mode: Dh (320 x 200 16) Address A002Ch, expected to read Oh, but read 1Dh instead *

indicates the video card has failed and need to be replaced.

If the issue occurs in the safe mode, then I'm suspecting a failure of the LCD backlight. (It warms up and quits) Also see if video stays on using an external monitor. If it does, then the LCD is most likely failing.

If video goes out on an external monitor as well, then the Video card is failing due to overheating. Make sure all vents are free of dust (Clean with canned compressed air) and the all fans are functional (Run the fan test in diagnostics) If fans check up, then video card is failure point. If fans fail diags, replace affected fan 1st

Usually this happens when the vista boot loader fails. During boot up, keep tapping F8 and then select Disable Automatic Restart... and get the stop error code which usually starts with 0x

First of all, check that the laptop is set to output video to the LCD. There should be a function key which will determine whether it is outputting video to the built-in LCD, the external monitor, or both. That should be holding down your "FN" key and hitting "F8." If it is on CRT ONLY, it should switch within 1-2 keypresses.

Secondly, take a good bright flashlight and shine it directly at the LCD panel from about 1-2 inches away. If you can actually see the graphics on the screen faintly in the background, your backlight is not turning on. The backlight is literally a bulb which lights up the screen, and they can burn out. It is repairable, and shouldn't cost more than $150.00 from a reputable repair shop.
