Next to the courser the little circle showing the computer is busy doing something constantly. so when i do want to do something, it takes forever. when it does make it to where i need to go it more times than not says program not responding. I'm running windows 8. I've tried several things such as cleaned out all unnecessary junk oh and i did a restore to an earlier date. as you can tell, I really don't know what I'm doing. my son needs this PC for college please help.
