Nostalrius Begins - Quality wow vanilla realm (1.12)

Ok so after playing for like 30min i get a black screen, and it sounds like a blue screen type of crashing so i have to restart my pc. I don't think it's my pc, i can play other games just fine. So please a little help.

Here is my pc it's not much but i think its more than capable enough to play vanilla wow.

Windows 7 32 bits
Intel pentium dual cpu E2160 1.80 Ghz
Ram 2gb
nvidia gforce 210 1gb

I have the exact same issue.
I find it totally random when the black screen appears.
Must reboot the computer, nothing else works.
Other programs continue running after black screen appears, though. For example, I can keep talking over Skype even after the black screen appears.
