Some terrible video problem with my laptop

[Sansoots]

I have some serious shit going on with my laptop. any help would be appreciated.

*The screen is completely black!*

It starts off with a black screen(Not even bios) and a fan spinning for about 3 seconds. Then the fan stops...but if I remove both of the RAM, the fan just keeps spinning forever...and you cant even press the capslock when both of the RAMS removed...Is it the (nVidia) video chip maybe? +There are no beeps at all, even when ram removed....-.-
... Maybe both ram sticks are damaged, but i dont have spare ones, i don't want to waste my money on something i don't even know if it works
I don't think than anything is fried on the mobo, i've checked ...the capacitors look ok and ther isn't anything that is burnt...cpu looks good, too
Things i've tried:.

*connecting the laptop to a external monitor, no luck.
*Hot air soldering the video chip, no luck.
*Reseating the Ram
*eraser trick - rub ram gold plated part with eraser
*Cmos reset
*tried to boot from another device (another HDD, CD drive)
*I'm planning to smash it with a hammer, see if it works...
..running out of ideas...so if you could lend me a hand i would be very thankful.
specs:
Processor:Intel Core 2 Duo T5500, 1.66GHz, L2 2MB
Ram:2GB (2x1GB) SODIMM DDR2 667MHz
HDD:120 GB 5400rpm, 8MB, SATA
Graphics:Integrated Nvidia GeForce Go 7400

Plz help. any help would be appreciated.

What caused this to happen? Did you go to turn it on one day and the screen was blank? Or did you make a recent change?

Do you have the power management turned on like the sleep mode and shut off after so much unused time? If so remove the battery reinstall it and see if it boots up. If so turn off the power management.

Yes, ofcourse i have done that, i have tried every possible solution and i'm working my ass off...lol...and this is my first laptop ever,I got it from my uncle... i used it for a week and then the problem occured. ..I don't have that much money to buy a new mobo or laptop,too...

But maybe I need a new Bios to boot from? i've heard that you can boot bios from usb...but i have no clue how to do that...

Maybe ask your uncle if it ever did a similar thing with him. Otherwise it sounds like the mainboard has failed.
