Hey guys. Been getting the BSoD lately. It started like last week. I don't think it's a temp problem, since I ran stress tests on it. I usually get the BSoD after around 20-30 minutes straight of CS:S and even just 10 minutes of playing Heroes of Newerth. i keep getting a sisgb6.sys error and dxgmm1.sys . I read other forums and they said to update my sis ethernet driver. i downloaded the latest, ran it, but the version stayed the same. :3 Uninstalled my display drivers, ran driver sweep, reinstalled, nothing.

Here's my specs:
Mobo: Asus P5sD2-VM
Processor: Pentium D 2.80 ghz (yes, it sucks)
Ram: 2x 2gb Apacer
Windows 7 Ultimate x86.
Display: Nvidia GeForce 9500 GT

I haven't had a BSoD since when I booted up CS:S last week. Since then, I'd get a BSoD every time I game. :3
I also ran the driver verifier as I read on Windows 7 forums. I'll attach my minidump file.

Help please!
