I have a 3-4 year old Micron T1000 with a P4 M 1.7 GHz CPU that died recently. The problems have just been building over the last year. Six to 8 months ago the power port started melting my AC adapter plugs, and overheating the adapter. Then recently, it began re-starting on its own about once a day. Finally, only the fan and CD would spin when it was turned on. After I ruled out the CPU and HD, I suspected a mobo failure, so I replaced it. But it still won't boot. The lights come on very briefly and their is a flicker on the screen when I hit the power button, but nothing happens. Could it be something else, or am did I replace it with bad mobo?
