My computer has several conflicting IRQs, which I think may be causing some instability in the system. I would like to reassign the conflicting IRQs to unused slots. However, when I open a device's properties from Device Manager and go to its Resources tab, the option to "Use automatic settings" is disabled/grayed out. Is there another way that I can change the IRQ assignments? I am using Windows XP-64 Pro. Thanks.

Here's a link to a screen capture of my Device Manager showing the current IRQ assignments: attachments.techguy.org/attachments/162339d1262368313/… –  Jim Fell Jan 1 '10 at 17:57
    
About 25% to 75% of the time when I boot my computer, it blue-screens (attachments.techguy.org/attachments/162503d1262669945/…). There are also other times when the computer seems to lockup, sometime after booting, for no apparent reason, which, just as hunch, I think is related to the first issue. The Event Viewer shows only DCOM errors, which, as I understand, doesn't mean anything. –  Jim Fell Jan 5 '10 at 5:42

the option to "Use automatic settings" is disabled/grayed out.

This is disabled because Windows automatically and successfully installed the device without conflict.

can you be more specific? which device? a screen shot of the device manager maybe?

Hello Molly. Yes, the Device Manager does report no conflicts, but viewing the IRQ assignments tells a different story. Here's a link to a screen capture of the Device Manager: attachments.techguy.org/attachments/162339d1262368313/… –  Jim Fell Jan 1 '10 at 17:56
    
shared IRQs are not uncommon and do not necessarily constitute a conflict. if there was a conflict between devices, you'd see a red X on one of the devices sharing the IRQ with another. –  Molly7244 Jan 1 '10 at 18:08
