Something Seriously Wrong: Random Shut Down, and VERY WEIRD Freezes

So my First Generation MacBook has the following:

1.83 Ghz
Two 2 gigabyte Crucial SO-DIMMs DDR2 SDRAM
320 WD Hard Drive
Snow Leopard
Bootcamp partition at 32 gigs. but nothing is in it.

My computer runs at 120 to 170 degrees Farenheit
normal is 120
high is 170

I got the memory upgrade when i switched to Snow Leopard

Now, the problems:

The computer shuts down. Randomly. Without Warning. Just pfffffffffft.
The temperature is around 150-170 during those
It will shut down no matter what i am doing

the other problem:

i have no idea what to call this, so since a picture tells a thousand words:

See those bars? ya, i have no idea what that is. the computer just stops responding. no mouse functionality. no keyboard functionality. nothing.

the only response i get is when i force shut down (press and hold the power button)

So, any help?

Looks like the graphics chip is going out.

the graphics is integrated onto the motherboard, not the cpu

and i would agree from the screenshots that the graphics card is dying

looks like it is overheating and force shutting down

a band-aid solution would be to try to keep your computer cool, maybe put it on a notebook fan cooler or use coolbook app to ramp up the fan, but your laptop is basically approaching end of life

thank you for your help. its been a good three years
funny thing is that my battery is still at 98% health

How much to fix the overheating (if posssible)?

and, im afraid to ask, how much for the graphics problem? *crosses fingers*

i assume you'd need to replace the entire motherboard?

any way to make the graphics thing go strong for as long as possible?
