BOSD, Stop Error Need Help Please

Hey everyone! I hope you're all doing ok =D. I just bought a new computer
and I am really happy with it, especially the fact that It has Vista =D. On
a side note though, I do infact get the Stop Error, some people call it the
"Blue screen of death" and it can prove to be very interrupting. I'm not
sure what to do, I will be doing what I normally do on the computer, talking
to friends, maybe browsing the web, and than my computer will just flash and
go into the Stop Error, Windows Vista suggests someway to fix it, but when I
try to put the hardware acceleration lower in the directoy it mentions I
cannot, because it says the driver won't allow you.

*So basicly my problem is that the Stop Error, or Blue screen of death, just
comes up randomly at times.*

Here are my computer specification if it will help you guys

2gb of ram
8800 gts factory superclocked by EVGA
2.13 core2duo E6400
700WAT PSU
320gb hd
