Had the same thing with an HP DV7 (IIRC) and nvidia 7600go. Baked it in the oven, and it booted up a handful more times, but ultimately died long before it should have. And I LOVED the more squarish form factor it had.. I got some $$ back from a credit card company (it died before 2 years were up), but I could only find 16:9 replacements..
