Boots fine, login screen is streaked through the middle.
About a month ago I replaced my hard drive, not sure if the two are related, but it worked fine for a few weeks, I upgraded to snow leopard and was very pleased. then one night it freezes, and ever since it boots fine, then at the login screen there is streaks across the screen through the middle. Sometimes I am able to log on, but after any other function or about 30 seconds it freezes. I know it's hardware because i targeted and the software functions fine. Any ideas? is it the harddrive? logic board??
Is this a good question?
