C2D is an older version of computer processors, thats why, is your computer 64bit or 32 ? because 64s use more cpu for graphics and animations etc. It also depends on your ram if you have 4gb ram (avg.) or more and still have these issues i think youll need to format your pc or get it cleaned somehow, the cleaners youll find online or the one thats built in arent that effective, if i were you id buy a computer with an i7 processor or i5 but with a high ram memory.

sorry i have to disagree with everything you say, C2D is old but fk, SRO is even more old, why don't you go see the requirements. Please understand more before you try to say something that you think might help
