I need a complete un-installer software

It's for my laptop. I installed Driver Genius yesterday and it found some driver updates, and I installed them, but since then my WiFi is being disconnected and connected at a random time gap. Other than WiFi I also installed Chipset driver, USB 3.0 drivers etc....now I wanna uninstall them completely and install only Lenovo's given drivers. The problem is chipset drivers, USB 3.0 driver, etc are not being showed under control panel (install/uninstall section), so is there some software or something which will help me show and then uninstall these system drivers? I don't a minimal trace of them in my system.

Thanks in advance.

Try using revo uninstaller as suggested above but I doubt whether it would find the driver uninstall files since even Windows' uninstall utility is unable to do so.
If not, you may have to remove the drivers manually from device manager.

+1 for Revo
excellent in removing traces during uninstall

Yeah guys, just after creating this topic, I installed Revo's trial version, it did remove all trace of an uninstalled file, but the problem is even that doesn't show the USB 3.0 drivers, or Chipset drivers, etc....it only shows what Windows install/uninstall manager shows, nothing more

PS: I was able to uninstall the USB 3.0 driver from device manager as it was clearly mentioned under USB menu, but I can't find the WLAN driver or Chipset driver!

Simply go to device manager and unistall the drivers which were updated. Use either Windows Update or Lenovo's official site to get them back. Make sure you download the WiFi driver beforehand.

I have. But I am not sure whether all the traces of new drivers were removed or not.
PS: Also, on Lenovo's website the Broadcom WLAN driver version is mentioned as 6.20.55.55, but when I install that same driver, it says 6.20.55.57, could be a fault on Lenovo's website or ... ?
