Scinetific linux GUI doesn't start

I am a new user of scientific linux 6 .
I am working on a project started by others and Unfortunatly , the GUI stopped working.
I need to find out how to trouble shoot the GUI to solve the problem .
What I have now When I open my PC is a complete black terminal .
I need to go back to the GUI and start troubleshooting.
Can somebody advice me how to start ?

I Did
#yum update.
#Xorg -configure : gives the error ( Missing output drivers. Configuration failed )

I tried also
#xinit : it gives errors ( no screens found )

#lspci اgrep VGA
( 00:02.0 VGA compatible controller : Intel Corporation Xeon E3 v3/4th Gen Core Processor Integrated Graphics controller ( rev 06)

#ls /usr/lib/xorg/modules/drivers
( ls : cannot access /usr/lib/xorg/modules/drivers : No such file or directory )

#startx
