i update my drivers and now wondows not working. Please help me
First lesson. NEVER use third party software to update your drivers, this is what happens all the time. Try system restore going back to a date before you ran the driver update tool. If that doesn't work get a program called "HDD Regenerator." Its great at fixing windows and HDD errors and restoring your system. If you can't use your system to download it, use a fiends, or download it at the local library. Follow directions to make a usb bootable verison. Change your Bios to boot from a usb. Reboot wiht it in the usb slot and just follow the directions to restore your computer.
