Hey,okay!

I have made a video on Sony Vegas&WMM everytime I try to render/save the video to my computer it crashes,turns off.(ect)

I have tried everything!
I have changed the IP address,and the virtual memory & Also I have defragmenting the hard disk!
Deleted some all the stuff I didn't want on the computer and even some I did want!

I have a vista gateway laptop.

It says memory(RAM):1.00GB (is that bad?)

Partition_1(C:) 19.6 GB free of 62.4GB

&
Recovery (D:) 4.13GB free of 12.0 GB

Thanks for taking the time to read this!

Have the largest hard drive installed you can afford. Your going to need it
very soon anyway.
While your at it have them add more memory, the max allowable.

If that does not fix your issues with Sony Vegas Pro9
