Hi, if anyone can help me with this, I'll be amazingly happy.
So I just bought a Titan Basic Custom computer (specs below), and everything seemed fine until I fired up the Left 4 Dead demo. About two minutes in, the computer bluescreens and reboots. I tried a few more times and got the same result. After looking at the dump files, I suspected that the processor driver was the culprit, and reinstalled it using the driver from the AMD website, rather than the driver CD.
The good news was that it stopped crashing because of the processor driver, but now it was crashing because of the Realtek audio (RtkHDAud.sys) and network (Rtenicxp.sys) drivers.
I tried reinstalling the drivers with the latest versions, but still got the same problem: every time I play the Left 4 Dead demo, it bluescreens because of RtkHDAud.sys. On top of this, the computer also bluescreens when I'm doing nothing in particular, and says the problem is either RtkHDAud.sys, Rtenicxp.sys or, on one occasion, ntoskrnl.exe.
I copied and pasted some of the dump files below. Any help would be greatly appreciated.
Thanks.
