Well I finished the world before, so now after a lot of faffing about I got Syberia up and running although in a small window, and am enjoying that as well, the end of the world before is really good, but I wont say anything else.......
The only people who can tell you more about the pc and provide the correct drivers etc are pc specialist and they won't do that without the ownership being properly transferred
Is this a pc specialist system, if so please post the full spec from your orders page,if not you'll need somewhere like Tom's hardware, as this is a dedicated forum, for pcs customers
No we need the full spec from your order page, it's explained in this link
