powerpoint 10 is very slow?

Last month I was facing the same problem with power point of office 2010. When I launch it and works for some time it hangs up and some time it restart by itself, It also works very slowly at that time. It really creates lots of problem for me. So for solving the problem I have taken the advice from the professionals. They told me that either your Office 2010 software is corrupted or it is happening due to some virus problem. So for that they recommend me to first of all install a new full version antivirus. After that perform the full system scan. Now Uninstall your office 2010 completely and reinstall it again. Now restart your system again check if it is working smoothly. I repeated the whole process and now my power point in office 2010 is working very fine. So you can repeat the same process and check if your power point resume its normal working. Hope by the end of this your office 2010 will work smoothly.
