Hello,

If you're pretty sure its your comm ports, boot up into your bios setup screen. (Tap Del while booting) Then go to the onboard devices page or any page that lists your com ports and change the property value to disabled.

    Its not an irq issue with your comm ports then. Windows just doesn't give a decent error message... ever.

    At post, press F8 until you get the boot options screen, if your PC gives you the boot from what screen, hit ESC and tap F8 immediately again. Boot into Safe Mode, forget the last config and or system restore options if you're given them.

    Once in safe mode and run scan disk across C: and reboot when asked you may have bad security descriptor errors. I know it sounds far fetched by it works more times then not in the field.

    Check for the latest drivers from you board maker and or reinstall them. If you have downloaded Vista SP1 uninstall it or if you have XPSP3 uninstall that they both came out of the shoot broken.

    Otherwise, you could have a bad ram module or board. This type of error is really flukey and the reference to comm ports could be any of hundreds used by your internet connection and not your serial ports. Sorry.

    Sorry there wasn't an easy answer for you this happens and many times I bring those machines into my home shop and just reinstall everything from scratch and that solves most trouble. I hope you found this helpful though and I couldn't do more for you.

    Thanks for using FixYa.

    If you have any further interest in pursuing this here I'm still interested as there are other methods to tracking down the error locking your machine up.

    If you decided to call in a tech or take it to a shop would you let us know please.

    Thanks,

IC VERIFY CREDIR CARD SOFTWARE WONT DIAL OUT AFTER SWAPING HD TO A NE PC. EXTERNAL MODEM WORKS FINE, SETTINGS ON ICVERIFY POINTS TO MODEM COM PORT. SOFTWARE WILL NOT DIAL OUT. aNY HELP?


Ok,

There's really only a few reasons this would fail beyond the COM settings. First, if the computer you're using has actual serial ports on the board and you're using a USB modem or if there are more than one serial ports it's possible you have either got the wrong COM assigned or that you have more than one trying to use COM 1. This will not cause conflicts with newer USB based devices but can when using actual UART chips on the motherboard or a mix of USB and UARTs.

Go into device manager and check for additional ports. Disable all COM ports except the actual modem and try again. If it still fails, check for DMA and IRQ conflicts. Do this by going into Start>All Programs>Accessories>System Tools>System Information.

Once open navigate to System Summary>Hardware Resources>Conflicts and Sharing.

Check for any conflicts with COM 1 and it's related DMA settings or anything sharing an IRQ with the modem. If you find any devices conflicting or sharing IRQ or DMA with the modem either disable the device or go into device manager, double click the offending device, click onto the resources page and find an alternate configuration that uses different IRQ/DMA that won't conflict. This will require a reboot for most devices.

Sorry my answer would be faster but I'm shaking almost a decade worth of dust and cobwebs out of my brain that have built up since the last time I even used a modem for ICVerify.

Hope this helps, lemme know how you make out,

chris

Hi, I have a problem with my Acer Aspire 5732Z laptop. Upon boot up, I get a blue screen saying there is an error with my computer, and the following file name appears: DRIVER_IRQL_NOT_LESS_OR_EQUAL Not...


It seems you have an IRQ conflict. You install a driver and it wants to use an IRQ which is already assigned to a different device. That's why you can start in safe mode because the drivers for your added devices are not loaded.

The computing phrase "interrupt request" (or IRQ) is used to refer to either the act of interrupting the bus lines used to signal an interrupt, or the interrupt input lines on a Programmable Interrupt Controller (PIC). The interrupt request level (IRQL) is the priority of an interrupt request.

In computing, an IRQ conflict is a once common hardware error, received when two devices were trying to use the same interrupt request (or IRQ) to signal an interrupt to the Programmable Interrupt Controller (PIC).

The PIC expects interrupt requests from only one device per line, thus more than one device sending IRQ signals along the same line will generally cause an IRQ conflict that can freeze a computer.

To view your current IRQ assignments you can open Device Manager. Click on START, click on CONTROL PANEL. Click on Performance and Maintenance. Click on System. Click on the Hardware tab. Click the DEVICE MANAGER button. Once you have Device Manager open, select VIEW from the tool-bar menu, and then click Resources by Type. Double click on Interrupt Request (IRQ). If you are experiencing problems with a newly installed/configured piece of hardware and the drivers are installed correctly, then check to see if it has its own IRQ channel.

To change an IRQ setting follow these steps:
-Right click on the device in the list (see above), and then select properties.
-Click the Resources tab.
-Remove the tick from the Use automatic settings option.
-Select a non-conflicting configuration from the pull down box.
-Click OK.

My dell E521 is now getting STOP errors after installin a video c


there is an IRQ conflict(internal adressing all the hardware parts)
you may want to set all the IRQ options in BIOS to auto and let the BIOS handle the IRQ adressing, disable the plug'n'play OS feature too so that the computer hardware manages the IRQs instead of windows. The blue screen is a sign that windows is causing problems, but done the way described this no longer will appear.

good luck

System unable to boot and showing signs of motherboard audio device conflicts(device type realtek)


hi iasmeer,

-to just boot up without any sound device,
remove any soundcards from the PCI- slots, disable the onboard sound device in the BIOS!
It looks like you are facing IRQ conflicts, your computer cannot handle all the hardware devices installed.
to solve this,
in BIOS set IRQ management so that the BIOS handles the PCI devices(set everything to auto),
disable the plug'n'play-operation system option to prevent windows from doing the same thing again( it'll then just take the IRQ information provided by the BIOS)
now enable the onboard sound device and make sure you have all
the drivers for the onboard devices(sound, LAN-card etc.) fitting your operation system on CD or thumb-drive, boot up and install the drivers.
Restart and by chance everthing isO.K. by now.

if not, please come back with more information on the sound device(onboard or not) and the winversion, so we perhaps can find you the appropriate driver(if you don't have it on the CD you purchased together with the mainboard..?)

Good luck

Hello annwiles,

Checking IRQ Conflict in Windows 2000 or XP:

1. Click on the Start button, and click on the Run option.
2. When the Run window opens, please type in devmgmt.msc and click OK.
3. When the Device Manager Window opens, click the View menu. Then, select Resources by Connection.
4. Expand the Interrupt Request (IRQ) category to view IRQ assignments.
5. Once you find your adapter on the list, check if the number that is assigned to it is the same as anything else on the list.
6. If your adapter is sharing an IRQ with another device, you may be having an IRQ conflict.

Resolving the IRQ Conflict:

1. Try placing the Network Adapter into different PCI slots. By doing this, the BIOS will assign the network adapter a different IRQ.
2. Disabling COM and parallel ports, or built in motherboard devices (sound chips, etc) in the BIOS may help to free up their IRQ's.

Note: Changes to the BIOS can cause major problems with your computer. If you are unsure, please contact the manufacturer of the PC for further assistance.

3. You may be able to assign IRQ's by PCI slot in the BIOS. Please contact your computer manufacturer for more information.

Win XO Pro displays MSG: "IRQL_NOT LESS OR EQUAL" on blue screen. Sounds like a hardware compatibility problem with SMCWPCI-G2 wireless card adapater. Any hints on how to solve this?


This almost always seems to be an IRQ conflict that the BIOS can't resolve with its plug n pray skills. When this conflict is passed to XP at boot-up time, XP panics and blasts you with this error message.

Before you start pulling cards, go about pulling cards, go into the BIOS and change the IRQ of the on-board compnents, if you can, and also disable any on-board components that are not needed. (such as the parallel port, on-board ethernet connection, etc.)

PCI GA-8ID533 V1.1


there is no PCI lock on any retail boards. But there are IRQ sharings and conflicts. Set IRQ to auto, if not, then manualy and if so, then disable a few things, just to free up some IRQs. All depends on the board, best is to consult the manual for the IRQ sharing table and work with that. (disable one SERIAL, IDE port or USB port if you need an extra IRQ) Also check for onboard equivalent to the card you are adding, disable the onboard part...
