Hi! I recently bought parts for a new computer and installed without any problems. Everything except playing Battlefield 3 has worked fine so far, although I haven't stressed the computer with any other game thus far. I have tried reinstalling drivers for the soundcard (realtek), the graphics card and some other things. I have tried running chkdsk and the built-in ram-test, with no luck. I have also reinstalled BF3. It often happens about 20-30 mins into the game and I have been monitoring the temperatures quite closely, so I don't think that's the problem. Very grateful for any help. I have attached the images of CPU-Z and my only minidump file I could find. I had 3 more but they got deleted, I guess from me running CCleaner. They were caused by dxgmms1.sys. My specs:MSI Z77A-G43 ATX Crucial Ballistix Sport 8GB 1600Mhz (2x4096MB) Intel Core i5 3450 3,1Ghz (Ivy Bridge) Optiarc AD-7280S SATA, OEM Cooler Master Elite 430 Svart Fractal Design Integra 500W XFX Radeon HD6870 1024MB 1TB Seagate Barracuda 7200rpm SATA 6Gbit/s Windows 7, 64-bit View attachment Minidump - Zhirgoyt.rar Edit: I tried disabling the Realtek High Definition Audio in device manager and I was able to play 20 mins before I had a different crash (to desktop), following a map-change. I'm gonna give it a longer go later tonight to see if it still works.
