Hi! A few days ago my graphic card started to have a strange behavior, but only during startup (have some vertical pink lines in half the screen) and when the 3D rendering starts. I've reinstalled all drivers and the problem continued. Then I thought it was overheating problems and, even though I was able to clean in from under it, it wasn't enough :( Can anyone tell me or send me a manual on how to take the laptop apart? Thanks

I have had that very same problem before. Unfortunatly it is all bad news. The card is going bad. You will have to replace the card. I wish there was something else I could tell you, but I know with 100% certanty that the card isnt any good. And the reason your other graphics card may not work is due to you not either uninstalling the 7500 drivers before you swapped, or some of the software affiliated with the 7500 were not completly removed during the uninstall process. Try this program http://www.guru3d.com/category/driversweeper/ to completly remove all dirver files for the 7500.
Does this happen only when viewing online audio/video, as opposed to inserting a music-CD into your CD-drive, and using Windows Media Player to play the music?
If so, then how fast is your Internet connection?
It probably is too slow to download and play at the same time.
So, when you click on a YouTube video, click "pause",
and let the download proceed for a minute or two,
and then click "play", to play what has been downloaded.
This issue could be either the Monitor inverter failing or it could be your Video card. If you have another computer available, plug the monitor into a different computer and see if you get the same behavior, if you do, then the monitor is failing and needs to be replaced. If on a different computer it works fine, then you may have a video card failing. Does it seem to happen the longer the monitor is on? Could be as it heats up, it starts to fail.
I'm not sure but I think this model uses an integrated graphics card which would then involve replacing the entire motherboard.
It may be that the screen backlight is getting old - they often age by showing a tint, usually it is pink but I have seen them go greenish.
Try an external monitor connected to the laptop via the VGA d connector. If the picture on the external monitor has a good colour balance then it is probably not a faulty graphics chip, and likely to be the laptop screen.
Either your graphics agp slot needs the driver updating or the card itself is faulty, check the agp slot for dust and gently moneuvre the card in the slot to see if the lines appear to change and check that therea are no bent pins in your connecting plug or card.
