Re: monitor displays vertical lines
Vertical lines can also be caused by an inverter going out, if the driver updates are not successful you might give it a little time to see if the problem area goes out completely, if its an inverter on the fritz it won't take long to go. Then you will know exactly where the problem is.
Just an update. If that doesnt work then your vid card is damaged and you need a new one. Considering it is 128 mb it cant be too new. Also make sure if your motherboard is agp you get and agp card and if its pci-e get a pcie card.

Test your laptop with an external monitor and find out if the external video goes bad too. If both, internal and external images go bad, you have a problem with the video card.
If external works fine and only internal goes bad, most likely it’s either bad video cable or LCD screen failure.
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.
Have you tried using another monitor or running another OS (a Linux Live-CD)? If yes and it's the same then the video card memory has died, nothing you can do . The entire video card is gone, buy a new one.
by process of elimination, try unplugging your monitor from your computer. turn it on, the built in self test should run. it will give you color coded boxes like red green, blue etc.. and would tell you no signal. if you cant see any lines during the buit in self test, then is the video card thats busted...
This may not be much of a solution but it seems odd that a video card would have some white lines gong across the screen. I would say its a driver error or the monitor is busted. Only way to tell is if another monitor is used on the system.
Does the Verical line on the monitor also come when the monitor is unplugged from teh system. If yes the problem is with the monitor. If no the problem is with the video card. The computer maufacturer may have given you cds to run diagnostics on the card. Eg on dell system , you need to press the f12 key 5 times after you turn the system on , to run the diags
is it a new graphic card? Sometimes that happens when the graphic card gets overheated and fries up some chips. and sometimes those lines appear when the graphic card has fault in Direct Draw. Try setting your BIOS settings to default. if it doesn't work, i recommend you to take the graphic card to the nearest hardware tech ;)
