Win 7 Aero Theme Keeps stopping after few seconds

[Aaron27]

Windows 7 Aero Theme Service keeps Stopping after a few seconds, i have already done :
Right click desk top>personalize>Trouble shoot problems with aero

It AlwaYS COMES up with the error Themes service isnt running :fixed
but after a few seconds it shuts off again.. It makes it to where i cannot see firefox close button,expand,minimize etc.. and completely makes the bottom task bar solid white and square with old buttons (like win 95) and various other windows including the volume button scroll etc..

I have completely reinstalled windows 7 ---does same thing
I have completely formatted the partition and reinstalled--does same thing

I have reinstalled all drivers from dells website--same thing
I have downloaded and used Driver programs that find missing software such as easy driver pro--Does not work still

I have gone into the manager-its set to automatic..Step 1 restart program, step two restart program..step 3 do nothing

I have had this computer for 3 years and run the same operating system and this has never happened.. it has crashed twice in those three years..the second time i had to buy and install and new hard drive in March of 2012..everything worked just fine until recently, Also Windows update has an error where it crashed while communicating with the server and now will not download updates its stuck at 0%. I have downloaded the Microsoft "Fix it" program and the program will not install it says:Error-Cannot open

try stopping the service in device manager then restart it, it may help. as for the updates issue, i would start a separate thread for that
