AMD X2 5200+
2x1GB OCZ Gold DDR2-800
Antec 380W PSU (came with NSK2480 case)
The system is connected from the onboard video to an LCD TV via HDMI. All standard stability tests (memtest, Prime95, etc) run without any errors or hiccups.
The system stays on 24/7, since it acts as the media center as well as a backup server and central file storage for the household. Every so often when the system is idle, it will bluescreen with error code 0x50, pointing at ati2mtag.sys as the culprit. I've attached a complete memory dump here (12.3MB 7-zip compressed).
All the drivers, as well as the motherboard BIOS, have been updated to the latest version. The system is running XP MCE 2005 SP3.
It seems as though the graphics are to blame. I've heard that ATI and HDMI still don't always play nice, so on my list of things to try in the near future is the following:
- Connect the system using a DVI-HDMI cable instead of the straight HDMI cable
- Install a dedicated graphics card (both ATI and nVidia) and connect it via DVI-HDMI
- Connect the system temporarily to a regular monitor via DVI and see if I can reproduce the problem
I was hoping that someone might be able to have a look at the memory dump mentioned above and figure out if there's anything else software/driver-wise that I can try in the meantime.
