Hello, So I was feeling a little adventurous (sp?) and decided to install some stuff: GDS, Quick Silver, G-mail notifier, etc. With all these things running, I was playing around, experimenting, and in quicksilver I typed in "itunes" then wanted to see my library...so this long list comes up on my screen with all my music and im like woah! (around 3000 songs...) . I try to scroll down this "list" that pops up, and I get the spinning beachball. I close every other program - this one refuses to close. It just wouldn't close no matter waht I did. So I held down the power button on my iMac. I power up the iMac...I hear the chime, and then I just get a white screen! Nothing more! Then, I press power again to shut off, try again, and I get a white screen again! I reset the SMC by powering off, removing everything, putting back in power, then powering on, and here I am now (it worked). What the heck might have happened? I'm just very suspicious...I don't want any hardware problems!
