I have had my Power Mac for 4 years now. This is the first problem I have ever had with it. Not sure where to go for help... First of all my computer froze. Nothing was responding. Had to literally pull plug. Have done this before with no problem. At next startup, everything was going extemely slow. It took forever to get to the login screen. When i did get there and login, again it took forever to do something. Eventually it takes me back to login screen and I can go no further. I have done an AHT and it gave me the Error...... 2STF/8/3:A... under the MASS STORAGE section. Didnt go any further. I did a disk utility repair and that didnt work. I have alot of personal stuff on my computar and dont want to lose it. Is there anyone who can help me.... Thank you in advance
