Hey guys, new to the forum here but certainly not new to computer forums (EOCF is my other home). Anyways I purchased a used G74SX for dirt cheap. I knew that it had issues and I'm ready to fix it. Anyways, when you press the power button the LED's flicker on and stay on; the keyboard lights for a second and then shuts off. No audible POSTing sounds are heard. The system fans are running but there is no display. I've done the obvious troubleshooting.
-Plugged system up to external video sources (HDMI, VGA). No display.
-Removed memory modules. Same results.
-Cycled the function keys for the display.
-Removed the battery, just used AC power. Same.

To me the initial assessment is CPU. I'm about to disassemble the whole unit to gain access to the CPU to see if it's seated properly.

Anybody have any thoughts? I don't mind replacing the CPU, but I will not replace the motherboard which I'm hoping is not the issue.
 
Just an update, I've determined it has to be the motherboard. Unfortunately with this model the GPU is built into the mobo, unlike my G50VT... I had to order a motherboard and hopefully that will fix the issue.
 
Sounds similar to my G60vx, except mine will sometimes make it through POST, sometimes well into Windows 7, then it will just freeze up. No heating issues at all. I am thinking mine is motherboard related too :(
