Windows 10: Windows 10 IRQ settings at sources tab grayed out

Hello all


I'm a bit of a noobie when it comes to this, but I wanna change the slot of a device concerning the IRQ's.


However, the options of the settings at the sources tab are grayed out. I use windows 10, and can't find anything on the interwebs about this issue. It only seems to happen with windows XP.


How can I enter the settings? Do I need some kind of authorization?


Thanks

IRQ conflict in Windows 10 but option to change interrupt grayed out

For as long as I have had Windows 10, I have been plagued by IRQ-related BSOD's. I finally learned that IRQ conflicts may be to blame. Using device manager, I learned that two devices, the USB enhanced host controller and my Nvidia GeForce GTX 645 graphics
card seem to be on the same IRQ. See the pic below.

I read that, to change interrupts for a particular device, I am to go into the device properties, click on the resources tab, turn off "automatic" settings and change the IRQ to one that does not appear to be in use. I would change one of the IRQ 16 devices
to IRQ 18, as that appears unused. However, neither device's resources tab appears to allow me to change any of the settings, as the "automatic" settings box is grayed out.

Is this an actual conflict that could be responsible for the BSOD's or is Windows managing these resources so that this is unlikely to be my BSOD issue? IF the former, what can I do about this if the "automatic" settings box is grayed out?

The computer always is powered on. Crashes occur randomly, at any time, whether the computer is in use or idle. To my knowledge, all drivers are current as I try to stay up to date on them.

I appreciate any tips you can provide. My tech expertise level is middling, so simpler explanations are better. Thanks.

Windows (10) and Irq conflict

I have a toshiba Laptop Qosmio X505

I have finally figured out there is an irq conflict with the hardware and windows 10 64bit it also happens in windows 7 64 bit

the video card, the usb, the firewire and the wireless are all on interrupt 16. This has been causing system lock up for a year or two. I finally recieved a BSOD that stated irq conflict and so i looked into it. ( I had wrongly assumed that irq conflicts
were a thing of the past so never assumed that ).

no diagnostic indicates an irq conflict.

I am pretty sure it is an IRQ conflict since the ram tests well, the cpu tests well, virus scans turn up nothing. When I disable wireless, usb, and firewire (just the nvidia video enabled) the machine keeps running. when i enable usb and use something like
a game pad the system locks.

I have done fresh installs, updated all drivers, installed windows updates. I have tried every bios version available for this laptop, All the bios have no setting for pci steering on or off.

in device manager pci bus has no irq steering tab and for all devices the use automatic settings and change settings are grayed out.

How do I fix this????? how can I move at least the usb to an open irq 3-15 or 20-22

IRQ conflict in Windows 10 but option to change interrupt grayed out

Ralf, thanks. See my response to MS, above. I've done endless, extensive testing of hardware and driver updating. The diagnostics and BSOD error messages suggest IRQ conflicts, memory conflicts, and driver issues, but I haven't figured out anything that
would be causing this. That's why the IRQ issue seemed to be worth exploring.
