Its not SP3, even if it had SP3 on it, the image I installed on it to try and fix the problem doesnt have it.
Saab. The image has all the latest drivers installed on it. Not a lot of info on their website and I couldnt find much about the issue. To be honest there have been issues for quite a while (with many diffrent builds and driver versions), but a re-boot has usually sorted it.
Had it been a warranty call then the motherboard would have been replaced as a precaution.
