UPDATE YOUR WINDOWS SOFTWARE FROM MICROSOFT OR YOUR VENDORS SITE, THERE MAY BE MORE SOFTWARE PATCHES FROM THE VENDOR TO FIX THAT TYPE OF PROBLEM

i found the solution at microsoft support website, but i just found in portuguese, so im gonna try to explain how to solve it.
u need to go to start menu and then on the star search u need to search for "regedit"
when u are inside the regedit, look for this subkey "HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Class\{4D36E965-E325-11CE-BFC1-08002BE10318}"

on the right side u need to del 2 subkeys

"upperfilters" and "lowerfilters"

close the regedit and restart the windows.

hope i can help u guys. it worked for me.

Don;t know if this is the cause of u're errors, but it might be do to the motherboard chipset drivers (the lack of them in u're windows version). If so, u have to make a copy of u're windows cd with all u're motherboard drivers included, and try to install with that cd. The same problem appears to all new laptops that do not offer XP support and only Vista support . In order to do the new XP cd, u\ll need a little program that u'l find on internet..... (for example: n-lite)
