The optical mouse on the system (usb connected) began acting sluggish so i replaced it with a logitech optical (usb connected). At bootup a message would come up saying mouse not detected, so i installed the software cd that came with the logitech mouse and this fixed the problem, mouse was working, but the typical message to restart computer after installing new hardware came up so i did. After restarting a message came up that said 'windows needed to configure my new mouse' and it went through some screens of asking things like 'if it would be used on the left side of keyboard or right' etc. After this was done, the logitech mouse still worked perfectly and I clicked through some files just to make sure all was well. Happy that the software installation made the mouse work, i shut the computer down to move it back to where it belonged. Here is where the real problem began.

After being plugged in and restarted, it would not boot past the windows splash screen.

On the black screen in white letters a message comes up that says "Plug and Play Configuration Error" "Press F1 to continue or F2 to enter set up mode"

When I press F1 then normal load, it loads to the windows splash screen and freezes there.

When I press F1 then safe mode load it loads entirely into safe mode but with no mouse support.

When I press F1 and opt for the bootlog.txt, i find a log of windows font errors, but have heard this is normal, and at the end of the log is a few lines of "enumerating unknown (HTREE\RESERVED)

I am inexperienced with computer issues and have had good luck with googling most problems. This is taking me to my wits end. I have unchecked everything in the startup files in msconfig from the safemode but still no normal load. It looks like there is an option under my computer--> mouse to reset the default settings, but this cannot be done in safe mode. The find new hardware cannot be done in safe mode.

If anyone has any ideas please let me know. I have written it as well as i can remember and if you need anything more specific, i can boot it up and look. Thank you for your time.

Plug and Play Configuration Error

The BIOS was unable to configure bus-resource. There may be an interrupt conflict which can't be avoided. Dell suggests that you remove some of your non-essential cards and see if it goes away. In one case this problem was due to a defective motherboard.

One thing you might check would be to see if there's an option in the BIOS to 'reset configuration data' or similar

Otherwise, try:

removing the mouse

uninstalling the mouse from Safe Mode

restart in DOS mode and rollback the registry with

scanreg /restore

I'm actually running an old GX1 - decent machines, but a pretty bare bones BIOS, so there's no apparent 'reset' option

Still, you can free up an interrupt or two by disabling the PS/2 mouse (IRQ 12) or ACPI (IRQ 9) which might allow Windows to reconfigure PnP resources

You could also try toggling PNP Aware Operating System , or similar, Off it is On, or On if it is Off, in the bios Setup

I have a Logitech Wheelmouse, model M-BJ58, an optical "combo" mouse than can be used with either a USB connection that is on the cord end, or with a PS/2 connection via a simple adapter that came with the mouse. It conflicts with some other USB devices when it is connected via USB - it always works fine connected via PS/2.
When it conflicts, the mouse sometimes blinks oddly while booting, sometimes the boot freezes, sometimes the other USB device in conflicts with does not work and the mouse works fine.
If you have another USB device connected, try disconnecting it. If your mouse is a "combo" mouse, connect via a PS/2 connection and you will probably have no problems. If your keyboard is USB connected but is a "combo" keyboard, connect it via a PS/2 connection and you will probably have no problems.

jboy-thank you for your help, i was able to try all of your suggestions except uninstalling the mouse in safe mode. when i tried this the screen would come up asking for the disk, as if i were trying to install rather than uninstall.

i had tried removing the mouse and even putting the mouse that had been sluggish back in before this post but nothing helped windows load in normal mode and even the sluggish mouse did not work anymore. believe me i tried all mouse in/mouse out combinations with restarts each time.

as u suggested in bios, i did disable the ps/2 mouse and the acpi was already disabled but this did not get me past the spash screen or stop the pnp config error.

the scan/regrestore took the new mouse software from the add/remove programs but did not stop the pnp conf error or enable windows to load in normal mode.

i cannot help but think this problem has to do with that extra little window that came up even after the new mouse was working saying "windows needs to configure your new mouse...will this mouse be on the left side of the keyboard or right.." i think i should have cancelled out of that window and every thing would be fine. hindsight i guess.

one thing i did want to ask is the step by step confirmation prompt. an older computer i had once would hang up everyonce in awhile and if i opted for the step by step confirmation at start up and hit enter after every prompt, the computer would get past the splash screen and load normally and would not have the problem again for a long while. i did try the step by step confirmation option on this computer. At the prompt that says "msmouse.vxd" when i hit enter for yes or escape for no, the commands then stop and the computer has to b restarted to get off of the black screen.
thank you again for taking a look at my problem and the time to answer

tubsandwires-thank you also for taking the time to help. there has been nothing else connected via usb to the computer, even the keyboard is ps/2, and i had initially tried using the mouse with the adapter that came with it as a ps/2 connection rather than usb. when this did not work, this is what caused me to install the software and decided to go ahead and use it as usb. i did try it again just now as ps/2 just to be sure and checked to see that the irq12 was set to on. still same error msg and no normal boot.

i do not see the PNP Aware Operating System in my bios.
thanks again for your help. it is crazy that the computer booted fine until this mouse issue (and the mouse did work fine after the software install , i had turned the computer off thinking all was fine), and now no mouse works, but maybe it is a wild coincidence and the motherboard has decided to go out or something. i feel like i have ruined my sons computer over forcing the logitech to work instead of going out and buying another that was the same as the sluggish mouse i was replacing. arg

Your mouse must be a "combo" mouse - if it came with an adapter it is one. However, it's possible you are confusing the adapter with one for something else, and the wiring within the adapter may not be compatible. As far as I have seen, a USB (female)to PS/2 (male) adapter for a mouse or a keyboard seem to all have the same wiring, but I could be wrong. To confirm that adapter works with the mouse, try it adapted to PS/2 on another computer.

IRQ 12 has to be on, but the PS/2 mouse setting must also be enabled in the bios in order for the bios to assign IRQ 12 only to the PS/2 mouse, which is a legacy setting.
If the PS/2 mouse was not enabled, most bioses will allow any PNP device to use IRQ 12. E.g. I have found USB and some network cards can use IRQ 12 if the pS/2 mouse is disabled in the bios.

Another thing you can try to free up an IRQ. Disable the USB controller in the bios, save settings, reboot. Enable the USB controller in the bios - save settings, reboot - that may shift the IRQ USB uses to a different one than it was using before, and make the IRQ it was using available to other PNP devices.

Another thing to try. Remove the power to your case, remove all the cards except the video card if applicable, making note of which one was in which slot. Try booting and see if the mouse works. If it does, add the cards one at a time, removing the power to the case in each case, until the mouse no longer works, if applicable. If a certain card causes the mouse to not work, try it in a different slot, or try swapping it's position with that of another card. Avoid using the slot next to the video slot if applicable, or the slot at the end of the slots next to the center of the mboard if it has no specific video slot - that slot is usually forced to use the same IRQ as the video slot or the onboard video, which is not a good idea.

Sure - as I'd mentioned (after rechecking mine), the BIOS in those old Dells is somewhat sparse

Kind of sounds like there may be a problem with the USB hardware or its drivers - at any rate, if you can, try removing any extraneous hardware and try rebooting to see if Windows will reconfigure - although that model does mainly consist of integrated hardware, so that may not be an option. You could try enabling ACPI to see if that changes things - and maybe try a serial mouse.

As stated at the linked page, possibly you may have a hardware fault on the motherboard, which would be unrepairable and perhaps impossible to workaround.

Those are generally good machines - - for their age (2000 - 2001). If you end up having to replace it, won't be the end of the world, better machines are very inexpensive

Tubey - basically, you're just reworkng what's already been said (only with way more verbiage, as usual)

i think i am making progress, still getting same error message and splash freeze at bootup but i now have a working serial port mouse to navigate around safe mode. In the device manager window i discovered a yellow flagged question nxt to usb. i removed this unknown device and voila after rebooting the serial mouse now works in safe mode. gonna keep working but much easier now that i dont have to use the keyboard for navigation.

at the moment i have done a scanreg/backup and am now waiting on the scanreg/fix, then i will recheck that bios and retry those toggling sugggestions.

do u think i will get anywhere with the step by step confirmation if i need to go that route?

thanks again guys!

well, i never did get past the windows flash screen or stop the error message from coming up. took your advice and junked it, put the memory in another dinasaur. have a great weekend!
