Hello all, I installed this card in a computer with the following configuration: MS8308EP Motherboard (SiS 730s, Firmware upgraded) Duron 1.2 GHz 256 MB RAM 300W PSU Windows Professional XP SP2 (fully patched) AGP port configured at 2x speed, disable write combine for stability (4x gave visual artefacts in 3D as did write combine) After installation the computer ran for a couple of hours without problems, both 2D and 3D worked fine. The following day it hung multiple times with a BSOD after anything between 5 minutes and 2 hours, regardless of whether in 2D or 3D mode. I have previously used this card without problems on a computer with the following configuration: Syntax S651m motherboard (SiS 651) Pentium IV 2.4 GHz 1 GB RAM 300W PSU Windows XP SP2 4x AGP, write combine enabled I have already tried re-installing the drivers. I have tried lowering the graphics acceleration, and then the BSOD no longer appears but gaming is sluggish. I have tried re-enabling write combine. I have tried lowering AGP speed to 1x. None of these have solved the problem. Obviously a 300W PSU is more than adequate for this rig. I am at a loss here, what should I try next?
