Locking up

I have been on Shockwave game site for a long time. The games Magic Ball 1,2,3, have all locked up a lot. We did what they said & still locks up. I have a new computer, Everything has been updated. It is now affecting all the other games, they are locking up now. I have 2 drives & it has crashed one of them. We don't have the money to go to 'Best Buys Geeks'. If anyone has any suggestions, please send. Thanks.
