Hi all. I'm a pretty Tech savvy guy and have a lot of friends and acquaintances bring me computers for repair. I've been doing it for years, but the other day, after repairing an Alienware M17-R1 I ran into something I've never seen before. This Alienware had a bad inverter, and a blown bulb. I replaced them both and now the laptop seems worse than it was before. Here's the issue I'm now having and the things I've done to this laptop.

When I power on the laptop it starts to boot, makes it to the windows logo screen, then the screen flickers a bit with a few fuzzy lines across it, the picture rolls a bit (Slowly, but like v-hold on an old T.V.), then the laptop shuts down completely on it's own. Sometimes it will cycle back on and go through the same rigamaroll other times it just stays shut down.

Here's what I've done to this laptop.
Replaced Inverter (Twice)
Replaced LCD (Not the bulb)
Replaced MOBO
Booted with and without battery installed

Before I replaced the inverter and LCD it seemed to work fine, except nothing could be seen on the screen without a flashlight.

I've also noticed that when plugged in without the battery, the power button is green. With battery, the power button is amber.

I'm going to check the LCD cable and reapply some thermal compound to the CPU, but I honestly don't know if that will help at all.

Any help solving this problem would be greatly appreciated.
