Yesterday I switched on the system and everything went smoothly until I looked in device manager and noticed one of my GTX 285 cards was missing. There have been no changes to my system outside of Microsoft downloads. After investigating the drivers were not loading due to an insufficient resource issue. I went through the IRQ and memory screens and saw no obvious conflicts. I reloaded drivers no joy.
I performed a hardware scan for new hardware and the missing gpu showed up in device manager with a problem indicator. Drivers could not be loaded
due to resource issue. I deleted drivers reloaded drivers no help. I then checked the IRQs for the GTX 285s and noticed one was IRQ 16 which had a large number of hardware components under it. I decided to try an experiment and disabled the sound card with irq 16.
I did a hardware scan and the missing gtx card showed up. Everything appeared normal. I went back to the sound card and enabled the drivers and it came back up no problem. The resource issue appears to be with the number of IRQs using address 16. A reboot of the system drops it back to one GPU being seen. Changing the IRQ would be the solution if it could be done.
But I see no method of changing IRQs. I've been around the block more than a few times with this issue and there does not appear that anyone has an answer.
BTW went in a reset ESCD and config data without any change. Nothing in Bios to help. I think I can rule out a hardware problem with the GTX board.
Still don't have an answer to what's really going on . Any help is more than
appreciated.
