I recently bought a computer premade (first I did not build in a while), and works like a charm aside from two games. Portal 2 and now XCOM (both purchased on Steam). Other games work perfectly (everything from GW2 to Civ V or The Witcher), it is only these. Kinda curious.
.dmp log included.
Note: Video drivers have been updated, but I didn't want to flash BIOS unless I was sure it was the problem. Too big a risk
Much thanks in advance!
