[QUOTE="SoaringDodo, post: 1031690, member: 149064"] I suspect that the card may be overheating under the additional load that the video/screen savers are putting on it. The key here is that you're having to wait 15 minutes or so. That would give the card enough time to cool down so that it begins working again. You don't mention what type of graphics card you have but if it has one, check the cooling fan on it. Also, right after the monitors go blank, place your hand above the card. Do you feel a great deal of heat coming off it? If it is over-heating, then you'll have to replace it because it's life-span has been greatly shortened and it will eventually fail entirely. [/QUOTE]
