I bought the base Macbook Pro last weekend. No problems to speak of until earlier today - two separate instances of waking the computer from sleep led to a black screen with about 30 or so multi colored lines on the top of my screen. The machine was unresponsive and the only way to fix was a hard reboot. I recently maxed out the ram to 4 gig (Friday). I have a feeling it might be related. Does this issue sound familiar to anyone? Did I not the seat the ram good enough (it showing 4 gigs properly)? Something else loose perhaps? Or maybe it's totally unrelated?
