Starting today, every time i reboot r shutdown i am hit with a stop error. When i reboot back to windows it tells me it suspects a video driver, but gives no specifics as i have technically 2 video devices, a TV card and my vid card. Im running Vista Ultimate 64 running the latest drivers (ati catalyst 7.10). Attached to this post are the 3 mini dump files i have in a zip folder to fit under the file attachment limit. I really appreciate it if someone can help me nail down the cause b4 i go n start messing with driver rollbacks.
