Everytime I boot up my system I get a new hardware found window.
I have checked my device manager and do see an "Other devices>PCI device with an "!"
When I remove this it simply comes back.
Any ideas?

If you've put this machine together yourself or added any PCI cards recently then it may sound silly but sometimes simply changing the PCI slot that a particular device occupies can solve this kinda of thing.

1.  If this is a brand-name computer, try to go to their website and start to see if any device is missing on the device manager?  Possibility could be USB, Modem, Sound..

2.  If you still couldn't figure it out, right-click on the device and select "Disable".. .that should at least get rid of the hardware found window.

Sorry, I should of gave more info from the start.
This is a system I put together.. Nothing has been added to the system at all or moved in the system.
I have tried Disabling the device, but as soon as it gets a chance it checks for it again and finds the troubled device and
prompts me with the New Hardware Wizard.  

Please help me stop the cycle of crazyness.

Thanks again guys

Can you track back to when this started to happen?  Perhaps you installed a new hardware, or upgraded a driver?   If this just started to happen, chances are it's something on the bios that got turned on recently.  Perhaps a USB port that was never used before?

Hi

When the wizard comes up, click next and follow the instructions, if the wizard reports this driver is no good, STILL say you want to use this driver restart and you wont be propted about a new piece of hardware, all it means is that that hardware or controller cant be used.

Make sure you have installed all the drivers for your hardware.

In some cases, this is something that comes with your video or sound or tv card  (audio controller, a svga in/out on your video card, etc)

Check through your driver disks and see if you missed installing anything.

I had the same problem with my vid card, it was the svga in/out feature and it installed like 3 different drivers, then the !!! went away in device manager.

Cheers

You CAN look up what the PC is seeing in the registry:

HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Enum\PCI (or HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Enum\ISAPNP if it is an ISA card)
Under there will be some keys.
The KEY NAMES are important. (Example:VEN_8086&DEV_2445&SUBSYS_00BE1028&REV_11)
Under these keys are some "Instance" keys
(example:3&29e81982&0&FD)
These instance keys have values called "DeviceDesc", that describe WHAT the device that the above key name references is.   The two above keys are part of my "SoundMAX Integrated Digital Audio" card on the PC I am writing this from.  If you do not have sound, you are looking for the key that references an "Unknown Device".  You should then pick apart the Key Name of the grandparent registry key of that DeviceDesc value that has "unknown device" in it.

Picking apart my example:
VEN_8086&DEV_2445&SUBSYS_00BE1028&REV_11
becomes:
VEN_8086  >> Vendor 8086 (suprisingly, Intel)
DEV_2445  >> Device number 2445 ([2445] AC97 82801BA / 82801BAM)
SUBSYS_00BE1028  >> Version Stuff
REV_11 >> Version Stuff

So, the big question, is how did I look this stuff up?

I have been using PLASMA Online (http://www.plasma-online.de) to identify "mystery" hardware on the machines I build/service, from their enumerated registry keys;

Once I know what the hardware really IS, I can use links that Plasma provides, or DriverGuide (http://www.driver-guide.com) to find drivers.

My first experience with this process was with a mystery modem;  this process help me identify a workable driver, by finding the manufacturer of the chipset on the modem. (the modem manufacturer had long since been dissolved)
