(About the pc...well dont mean to offend you or so, but i worked for 3 months as service technican for a middle-big hd/mp3/tv company. Many people saying everything is fine with their rig or hd

Do you use beta drivers for your graphic card? if so, switch to non beta drivers, or try switching back to a older version. I had never any issue with beta drivers, but sometimes the devil is a squirrel.
Did you try it without using any mods at all? Vanilla rome.
What mod-translation for DeI do you actually use? There are at least two. MuppetMan -one author of a used translation - is not using DeI currently, but he (thx again man) was nice enough to update it for 0.9. Still we can't expect full support if any problem occurs (which is totaly reasonable).
Btw, what DeI do you actually using? Early release of 0.9 had some crashes in. 0.9h should not having those issues.
Edit: You should check the official support forums too. And there is no need to open a second thread about this issue, especially because this thread is still on the first two pages
