Vegas pro 12 Stops responding all the time

I'm having big issues with vegas pro 12.0 Latest build
It stops responding so much...
Its something to do with my driver maybe?
Because
My stats

AMD Fx - 4100 Quad-Core processor 3.60 gigahertz
8GB DDR3 RAM
Windows 7 64 bit
NVidia geforce GTX 550ti

I highly doubt my computer can't run it
I don't have a pro computer, but it should be able to run it

Vegas has stopped responding:

When renderring a raw clip to decrease file size
When renderring an entire made out video, introduction, outro, few effects, watermark
When i removed an audio track(file size 3mb)
When i added raw footage to the track
When i added the smooth/enhance fx to an audio file


When i renderred my intro and outro, it was fine

At the moment i am trying to render a 12:14 minute video
The raw clip in the middle is 650mb
I have tried renderring a 5 minute 230mb video with it aswell, no luck

When i actually get it to start renderring ,it dies at 20-30%

I have tried giving the vegas process high priority, no luck
I have no driver updates for my graphics card
No updates for my processor

I am really desperate to get this to work

I don't think its doing any procedure thats making it crash, i think just in general the program is crashing
