hello, i new to this forum and i'm having more than a few problems with my laptop lol. anyways, first i reinstalled windows mainly because the wireless card quit working. that was the first time i reinstalled it in my laptop and its about 3 years old. so everything seemed to run fine after i also installed all the drivers too. the problem i am having is the computer won't turn off properly when i either press the power button or when i go to start and select turn off. it will go to the desktop background and thats it. so i have to use quick shutdown by just press and hold. then the computer after a certain amount of time running, most of the programs will crash that are running and it won't let me run any new programs. and the final problem is everytime i turn off and then start my laptop back up, all the setting reset to default. the most common one i can think of when i choose all the icon in the bottom right hand corner to hide, they reappear again after new start-up. i also have the low virtual memory error that keeps popping up every so often. btw its a dell inspiron 6400 with windows xp. any help would be great, thank you.
