Lenovo G575 - no vga, turns off fast

[Scootie]

Hi guys,
This little guy is giving me some headaches.

I changed ram and flashed a new bios but does only one thing. After being turned on, it stays so for about 8 seconds then turns off, no vga signal on lcd or external screen in the meantime. The board doesnt have an "integrated vga" only a cpu which me thinks contains the vga cip as well.
Should I reball the cpu, could the cpu be fried or the problem lies with the sb?
I measured as best as I could the board but I dont call myself an expert on this territory.

P.S. I managed to grab my hands on a schematic, will see tomorrow of it checks out.

Didnt have time to check what kinda of a board is. Will do first thing in the morning. No chance for a reball, you say?

see if you got any shorts with that sb and when you take it off and put it back
