I have a Dell Inspiron 2650. The problem is that when I turn it on I hear the Processor fan rev up run for a second and that's it. No video on the screen or apparent activity on the HD. The machine was working fine but one day I turned it on and this happened.
What I've tried so far:
Replaced the ram, HD, Processor, CDROM & Floppy with known working counterparts.
I've hooked the computer to an external monitor and no video was shown.
I personally believe its going to take a MOBO to fix it but just wanted to post here first to see if anyone had any bright ideas. Thanks advance.
