I was using last night when it locked up, and the screen went crazy, lines going accross, flickering, ect. So, I manually powered it down, now it will not boot. No video, no hard drive activity, the power led comes on, the fan runs for a min, then stops. Any ideas? The best buy replacment ended in August, go figure. My guess is something is dead, the big question is, new laptop, or pay to see if it can be fixed/refurbed.
