I have a Toshiba Tecra laptop wiyh a nvidia fx go5200 display adapter.This display adapter seems to have gone bad,device manager says the adapter is not working or has a problem,I have tried to update the driver but that does not help.The screen is very blury and the mouse pointer seems to leave trails.I can barely read most text and some not at all,the computer seems to work fine other than that I can use all functions as long as I can see the things I need to click on and such.If the display adapter is bad ,is this something easily replaced if opened up,and is there any other possibilities or solutions. roughneck.
