At first u need to hit CTRL+ALT+DEL and run TASK MANAGER ... in task manager hit FILE - NEW TASK(Run...) and u must check "Create this task with administrative privileges." type in CMD and hit enter ... now u get in command line window and here u need type those commands and beware ! it must be exactly same as i put here in brackets but no with them !
First line is (REG ADD "HKLM\SYSTEM\CurrentControlSet\Control\SafeBoot\Minimal\MSIServer" /VE /T REG_SZ /F /D "Service")
hit enter and message "The operation completed succesfully." should appear after that dont close that window put in second command
Second line is (REG ADD "HKLM\SYSTEM\CurrentControlSet\Control\SafeBoot\Network\MSIServer" /VE /T REG_SZ /F /D "Service")
hit enter and message "The operation completed succesfully." after that type "exit" hit enter and go to START and RESTART PC
Go to in windows "Advanced Boot Setup" (when booting windows hit several times F8 key) and select from menu option "Disable Driver Signature Enforcement" after that dont do anything else !! Just restart windows and again go to "Advanced Boot Setup" now select "Safe Mode" and login as administrator ... go to in device manager and click remove/uninstall driver for that unwanted "intel 4000 chipset" if it ask if remove software added with this driver then click yes and restart again to "Safe Mode" head again to device manager and u should see "Standard VGA graphic adapter" or similar "VGA Compatible" if u see that in device manager instead of "intel" click X to close manager and install AMD catalyst for ur graphics downloaded from
http://support.amd.com/us/gpudownload/Pages/index.aspx ... after install driver it asks for restart click yes and from that point windows boot normally no more safemode is needed, go to device manager check if it shows ATI AMD HDxxx driver.
