I uninstalled my amd drivers using the control panel and clicking amd software then clicking clean uninstall. after the pc restarted after a few seconds in the desktop it freezes. I tried installing the driver on safemode but it says "Error 99 – AMD Installer Cannot Continue Because the Driver has not Been Digitally Signed" during the installation. I have also tried sysyem restore but it doesn't work. I have also tried disabling the On the device manager on display adapter it says "standard vga graphics adapter" and on dxdiag under the display tab it shows nothing. i hope somebody can help
