Let me start out by saying I am no way computer savvy! I've read that Inspirons are notorious for having overheating issues. Mine is no acception. It normally would overheat and shut down on me. After cooling off it would boot back up when I turned it on. Well, yesterday it booted up without any display. The screen was black. I turned it off and tried again. Same thing. I connected an external monitor. No change. I took out the fan and heat sink (read up on how to do that). Blew out 2 massive dust bunnies (should have done that months ago). Turned it on...no change on internal or external monitors. I did hit F8 when I connected the external. Does anyone have a suggestion as to what my next step should be? I re-posted my issue in this forum. I posted it earlier under the wrong forum. I hope this is the right one.
