IRQ Conflicts - Freezing PC

Megadether · May 3, 2006, 09:09 AM

Recently I've been having very bad freezing problems with my pc, so bad that it would actually freeze in the bios

Anyway I figured it might be IRQ sharing conflicts and low and behold I found these in msinfo:

Code:

I/O Port 0x00000000-0x00000CF7	PCI bus
I/O Port 0x00000000-0x00000CF7	Direct memory access controller
	
I/O Port 0x000003C0-0x000003DF	VIA CPU to AGP Controller
I/O Port 0x000003C0-0x000003DF	RADEON X800 XT Platinum Edition (Omega 3.8.231) 
	
IRQ 10	Am1772(tm) Wireless LAN Chipset
IRQ 10	WinXP Promise SATA378 (tm) IDE Controller
IRQ 10	VIA Rev 5 or later USB Universal Host Controller
IRQ 10	VIA Rev 5 or later USB Universal Host Controller
	
IRQ 11	RADEON X800 XT Platinum Edition (Omega 3.8.231) 
IRQ 11	OHCI Compliant IEEE 1394 Host Controller
IRQ 11	VIA Rev 5 or later USB Universal Host Controller
IRQ 11	VIA Rev 5 or later USB Universal Host Controller
	
IRQ 9	Microsoft ACPI-Compliant System
IRQ 9	SCSI/RAID Host Controller
	
Memory Address 0xA0000-0xBFFFF	PCI bus
Memory Address 0xA0000-0xBFFFF	VIA CPU to AGP Controller
Memory Address 0xA0000-0xBFFFF	RADEON X800 XT Platinum Edition (Omega 3.8.231) 
	
I/O Port 0x000003B0-0x000003BB	VIA CPU to AGP Controller
I/O Port 0x000003B0-0x000003BB	RADEON X800 XT Platinum Edition (Omega 3.8.231)

Any idea as how to fix this?

In general, shared resources are not problematic. Look in the Problem Devices which is located in the Components category in the System Information, it displays information about devices that may have a problem, including the device ID and the error code.

provide us more details about the problem, hardware specs and USB devices??

Specs:

Athlon 3400+ Newcastle (Running at 45 under stress)
K8T Neo-FIS2R (Oldish bios seems to work best)
Ati X800Pro (flashed to X800XT) AGP
512MB PC3200 Twinmos (Tried various timings to no avail)
512MB PC3200 No name brand (Tried using different memory, same problem)
Audigy 2 ZS (using latest drivers)
Maxtor 160GB ATA
Maxtor 300GB SATA
450W Power Supply from high end case (replaced crappy brand one with this)

Currently only Logitech usb mouse plugged in

My problem is best described as a stutter then freeze with high pitched sound looping out of my speakers. I assumed this might be the 'Squeal of death' so I removed my audigy but I still suffered the same problem minus the squeal. After a reboot I'd encounter freezes whilst loading windows or whilst the pc posts.

This isn’t a temperature issue as I have left it for hours returned for it to freeze whilst booting. After fiddling in the bios changing voltages/timings etc I'd eventually get it running alright for a while until it freezes again then I’d have to repeat the process to get it to load windows

ok, thanks for the info.
wait and see if anyone around here get the same problem? and perhaps a solution to it as well? if i can think of anything i'll post.

about the "Conflicts/Sharing" under the Hardware Resources category in System Information (Msinfo32)
the Conflicts/Sharing displays devices that share the same resources, such as direct memory access (DMA), IRQs, I/O port address and memory. and again, in general, shared resources are not problematic, but investigating potential conflicts can help resolve issues.
If you are having a problem with a device, check Conflicts/Sharing to verify that there are no sharing conflicts.

locate the device in the Device column in the details pane (right pane of the msinfo32), and then verify which resource the device uses in the Resource column. Devices that share the same resource have duplicate entries in the Resource column.

in your case example, you have 4 adapters that share the same IRQ channels, IRQ 10 and 11.
IF the problem device shares a resource with another device, there 'may be' a conflict.
you can use Device Manager to troubleshoot the problem.

IF there are any device conflicts*, in the Device Manager you'll see a question mark, exclamation point or other icons that indicate a less than perfect installation in front of the problem device, you can then use the information in the Conflicts/Sharing to help solve the device conflicts problems (if any). otherwise, the devices are sharing resources, but not conflict.

anyway, if you have changed any settings/options in the BIOS setup, check and see if the option 'IRQ assignment' or 'Resources controlled by' has been changed from the default value, try setting the option to "Auto", this allows the BIOS to automatically distribute interruption resources.

The above IRQ info was from the Conflicts/Sharing tab, sorry I should have clarified that

That is why I have a feeling that might be the issue, although I don't get any problems under device manager. Surely if theres a conflict that might explain lookups while the machine posts? If it was heat after cooling it would have booted and if ram/cpu needed more juice upping the voltages would have fixed it.

Obviously with pci cards you can just shuffle them arround to get different IRQ's but with the usb hub controller and graphics card at 11 I haven't a clue how to change them.

It doesn't actually sound like IRQ conflicts to me, IRQ conflicts occur extremely rarely if you just let Windows XP and the BIOS manage everything automatically.

Have you tried running something like Prime95 to test the cpu/memory?

And what brand is the PSU?

actually, you didn't have to clarify that. i knew the IRQ info and other shared resources info that you posted above were from the Conflicts/Sharing tab. that's why i tried to explain about the tab Conflicts/Sharing above.

Sharing of IRQ is a feature of ACPI in Windows XP, it automatically allocates IRQs and resources. it shouldn't cause any problems unless you have hardware that doesn't like sharing an shared PCI slot (some SB Live cards don't like other cards), bad hardware, bad drivers etc. (remember, you've tried removing the audigy card, but you still having the problem) see below about the problem devices.

on some other Windows XP's + ACPI systems that have and use more onboard devices and/or add-on cards you would see many more shared resources info in the Conflicts/Sharing tab, and there is no device conflicts problem in these systems.

anyway, the below information "How to Use System Information to Identify the Cause of the Startup Problem" is also apply to Windows XP.

How to Use System Information to Identify the Cause of the Startup Problem

The System Information tool displays a comprehensive view of the computer's hardware, the system components, and the software environment. Use this tool to help you identify possible problem devices and device conflicts.

To do so, follow these steps:

1. Click Start, and then click Run.
2. In the Open box, type msinfo32, and then click OK.
3. Check for problem devices or device conflicts.

To do so:

a. In the console tree, click to expand Components, and then click Problem Devices.
Note any devices that are listed in the right pane.
b. In the console tree, click to expand Hardware Resources, and then click Conflicts/Sharing.
Note any resource conflicts that are listed in the right pane.
c. If you identify a problem device, perform the appropriate action (for example, either remove, disable, or reconfigure the device, or update the driver), and then restart the computer in normal mode.

You can use Device Manager to remove or disable devices and their drivers. For more information about Device Manager, see the Use Device Manager to Identify the Cause of the Startup Problem section of this article.

If the computer starts correctly, that particular device may be the cause of the startup problem.
