i am running my laptop with windows xp professional-sp3. recently i have downloaded windows live applications and using only WINDOWS DEFENDER, MICROSOFT SECURITY ESSENTIALS. earlier i was using ms office 2003 professional and my laptop was running very smoothly. but now i am using ms office 2010 beta. and now my system is responding too slowly. i have checked and deleted the softwares which i am not using right now, defragmented all my hard drives, everyday scanning for anti-virus, spyware,malware. but the system performance is not improving at all. please guide me how to check all the possible errors/issues and how to fix it.1 person needs an answerI do too

the beta could be messing with something on your laptop. delete it and c if preformace returns if not system restore to a point before you installed the program
