[kenpattx]

I have a Dell Inspiron 6400 (2gb Ram) been using it for more than 3 years works great..went to work Thur nite hooked everything up as normal, the extended vga monitor would not extend I tried a different cord no work...tried a different monitor, no work I tried to reset the settings in the control panel display,,no work luckily I had another laptop in the car, I got thru the nite..the next day at home I put the Dell on line downloaded all updates, downloaded all drivers,,still no work..I hooked a svideo cable it works, but a bit fuzzy ,,,,,where do I go from here
