Intermittently PCIe devices (tuner cards) are 'going away' from the media center application and missing from Device Manager. Device Manager Scan for Hardware Changes do not find the missing card. A reboot reinstates the card.
Win7x64, Gigabyte Sniper M3 motherboard, i5-3570K 2 x Hauppauge HVR-2200. The system was rock solid for a couple of years before the motherboard upgrade. Using Integrated Graphics - no PCIe Graphics. Have tried moving tuner cards between slots but symptoms persist. All latest BIOS, chipset drivers and all other drivers are installed.
Have opened a ticket with Gigabyte but no response yet. Any advice with this being a known issue or with troubleshoot will gratefully received.
