Invalid parameter

An invalid parameter was passed to a service or function.

A parameter is a value that is sent to a service or function, typically part of the Windows API.  For example, if a service expects a value 0 or 1, but gets a value of 452, it can issue this type of exception since it doesn't know what to do with the unexpected value. 

This exception may be an indication of some kind of data or stack corruption, and may have occurred by another program, service, or driver. This  exception issue that can be difficult to solve if the primary suggestions fail to fix it.

While we've marked it as Fatal, depending on the program and what it is doing, the program might handle this problem automatically or issue a non-fatal error.

Most exception errors are the result of a software bug. If the faulting program is identified, check if a newer version is available that corrects the issue.

Be aware that in some cases the fault might lie elsewhere, such as an operating system file, driver or other defective software that is running.

If you are unable successfully boot into Windows because of the fatal error, Windows has an option to reload registry information from the last successful boot. To revert to the last successful boot:

1. Reboot the computer.
2. Near the end of the BIOS messages or graphic, but well before anything appears from Windows, press the F8 key. You may only have a few seconds to get the right spot to press F8 before it attempts to go into Windows. If the BIOS complains about a pressed key or asks you to go into BIOS setup, you've pressed F8 too soon (Don't go into BIOS setup).
3. When successful, you should see a black screen with white text "Windows Advanced Options". Use the up or down arrow keys to highlight Last Known Good Configuration and press Enter.

Install the latest Windows software updates. Don't forget to check for non-critical updates too!

To manually get updates, open Internet Explorer (you can't use a non-Microsoft browser for updates).

For IE 8 and later: Click on Safety, then Windows Update. Follow the instructions.

For IE 7 and older: Click on Tools, then Windows Update. Follow the instructions.

If you can get the system up for more than a few minutes or can use safe mode, try removing the last installed software application or driver.

For removal of an application (Windows 7 & Vista):

1. Click on Start, Control Panel, then Programs and Features.
2. Select the software to uninstall and select Uninstall.

For removal of an application (Windows XP):

1. Click on Start, Control Panel, then Add or Remove Programs.
2. Select the software to uninstall and select Remove.

To disable a driver:

1. Bring up the system information dialog:

   On the keyboard, press the Windows key + Pause/Break.

      or

   Select Start, right click Computer and on the drop-down, select Properties.

2. Click on the left side option Advanced system settings (7/Vista only).
3. In System Properties, select the Hardware tab, then click on Device Manager button.
4. Find the hardware/driver of interest (you may need to expand a choice at the "plus" graphic) and double click the choice.
5. Select the Driver tab. Here you can perform a number of actions such as update the driver, roll Back the driver to an older version, disable or uninstall the driver.
6. Click OK to exit, then close the Device Manager and other previously opened dialogs.

You may have a defective memory. This is even more likely if it only occurs when the system is cold or hot, but not all the time. Use a memory tester to confirm if it is defective or if you have spare memory, try replacement.

Windows 7 and Vista include a Memory Test program when booting from the Windows Installation DVD. Step-by-step instructions with screen shots are available at Using System Restore on 7/Vista/2008 as part of System Recovery.

Several software products that also provide memory and video diagnostics includes Fix-It Utilities Professional and SystemSuite Professional. Other diagnostic products include Eurosoft's PC Check and Iolo's System Mechanic.

Additional Memory Solutions:

• Confirm all the memory is of the same type and speed. Many motherboards only work correctly when the memory is installed with matched sets and matched speeds.
• If you added or changed your memory just before this problem occurred, try reverting to the prior memory configuration to confirm it's the source of the problem.
• Check that the memory is fully seated in the sockets. Memory sockets often have side latches that need to be upright to indicate the memory is correctly locked in place.
• Confirm the memory resides in the correct slots on the motherboard. You'll need to refer to the motherboard manual to confirm this. There is little consistency, even within a single vendor. Some systems require that memory is installed as matched pairs, but not always adjacent to each other!
• It's also possible the memory problem is on the video card, as they often contain additional memory. The video card should be tested and/or try a different video card to see if the problem goes away.
