Windows 7 - keyboard and touchpad stopped working after resart

i have read about similar problems on here but none of the solutions worked for me. the keyboard seems to work just fine until the "starting windows" screen appears then absolutely nothing. i've tried reinstalling the alps pointing device drivers, i uninstalled then installed the newer version, nothing seems to work. the computer was working just fine until i came home from work and turned it on. this same problem happend about 2 months ago and it magically fixed it self, i just never turned the computer off again. i have 2 identical sony vaio VPC-EB33FM/BJ models, and have compared all the drivers and settings, they are the exact same (except the newer version of Alps on the broken one). i ran one of those "scan for new drivers" programs that ask for money to update drivers that it says are old and it said that the HID keyboard device driver is way out of date along with several others, but once again they are the same as the ones on the computer i am using now and this one works like a champ. anyone have any ideas? would be truely grateful for all input, thank you.

Hello looman16,

Welcome to Sevenforums.

I suggest you Uninstall the Newer Drivers and then restart your computer.

thank you, tried that, nothing. im mildly tech savvy but i am really stumped on this one. if i had a windows disk i would just reformat and start over but i dont.

Most Laptops come with it Ready on another partition.
