2. As per Windows 7 upgrade assistant guide i have lastly insert DVD of Upgrade assistant to upgrade drivers and other things but when i click on next then it freezes and giving Microsoft .NET Frame Unhandled Exception. What is this problem? I want to upgrade my drivers from CD but it is giving error.So please help me out guys.

3. This problem is related to 2 point that as i wrote that i am unable to upgrade drivers so i tried to find out drivers for Windows 7 32 bit on Dell site.But when i saw Dell site have drivers for only Windows 7 64bit.. So now what can i do? I can't install drivers and because of driver problems laptop is not working properly and i can't download drivers for Studio 1555 for windows 7 32 bit from site because it is not available.

So please do needfull.
