Running the PSA diagnostics and memory test will result in all tests passing. This error is mainly evident memory parity error dell when booting into Safe Mode with Networking. If the Network card is disabled in the BIOS, the system will boot to Windows normally. Back to Top 2. Solution Please refer to www.dell.com/support/drivers and download the latest version of the Broadcom Gigabit Controller driver. This can be found under the Network drop down within Drivers & downloads. Download the

Network Driver preferably on a different system and save to a USB memory key. On the suspect system, restart and boot into Safe Mode. Uninstall the Broadcom drivers, including the INF file so the system does not reinstall the driver automatically. Please refer to the instructions below on how to delete the Network driver for Windows XP Windows 7 Windows XP Follow these steps to remove the Network Driver after you have the latest driver ready for installation: Remove the driver software from Add\Remove Programs. DO NOT reboot. Check Device Manager to make sure the driver is no longer present. Navigate to C:\Windows. Click Tools at the top of the window. Click Folder Options. On the View tab, click Show Hidden files and folders. Click Apply, then OK. Open the inf folder. Scroll down to the oem inf files. There will be an inf and a pnf. Double-click on oem0.inf. Look at the description in the header for the commodity listing. If it is not it, then go to oem1.inf and o

hangs or stops responding during the Windows start-up process, and may be the result of a number of hardware or hardware configuration problems. What does the NMI http://www.tech-faq.com/nmi-parity-check-memory-parity-error.html Parity Check/Memory Parity Error Look Like? A number of error codes can be displayed when the error occurs. These include: NMI: Parity Check/Memory Parity Error, NMI: Bus Timeout, NMI: Software http://en.wikipedia.org/wiki/RAM_parity NMI generated, NMI: Eisa IOCHKERR board x, NMI: Channel Check/IOCHK, or NMI: Fail-safe timer The error codes typically start with the “*** Hardware Malfunction” message and a display message indicating that memory parity the computer or system has been “halted” follows. Why does the NMI Parity Check/Memory Parity Error Occur? The NMI Parity Check/Memory Parity error typically occurs if a computer hardware component is damaged, malfunctions, or if an incompatible driver is installed on the computer. How to Fix the NMI Parity Check/Memory Parity Error Most hardware problems that trigger this error involve the computer's memory parity error RAM, motherboard, cache memory, or a hardware adapter on the computer. The following are troubleshooting steps that can be taken to identify the cause of the error: Verify Your Computer's Memory Step 1 – Remove any new RAM modules that have been installed on the computer. Step 2 – Restart the computer to see if the error message continues to be displayed. Step 3 – If the error is eliminated, then replace the RAM modules that were installed. If it persists, repeat the process but only leave the minimum amount of RAM necessary to boot the computer in order to determine if the computer has faulty RAM. Step 4 – Replace the faulty RAM modules if they are the source of the problem. The Microsoft RAM diagnostic tool found at: http://oca.microsoft.com/en/windiag.asp may also be used in order to help identify faulty computer modules. Verify the Adapters on the Computer Step 1 – Remove all adapters that are not required to run or start the computer. Most Windows computers can be run with only the video and drive subsystem controller adapters. Step 2
in random access memory, and the subsequent comparison of the stored and the computed parity to detect whether a data error has occurred. The parity bit was originally stored in additional individual memory chips; with the introduction of plug-in DIMM, SIMM, etc. modules, they became available in non-parity and parity (with an extra bit per byte, storing 9 bits for every 8 bits of actual data) versions. Contents 1 History 2 Memory errors 3 Error correction 3.1 ECC type RAM 4 See also 5 References History[edit] Early computers sometimes required the use of parity RAM, and parity-checking could not be disabled. A parity error typically caused the machine to halt, with loss of unsaved data; this is usually a better option than saving corrupt data. Logic parity RAM, also known as fake parity RAM, is non-parity RAM that can be used in computers that require parity RAM. Logic parity RAM recalculates an always-valid parity bit each time a byte is read from memory, instead of storing the parity bit when the memory is written to; the calculated parity bit, which will not reveal if the data has been corrupted (hence the name "fake parity"), is presented to the parity-checking logic. It is a means of using cheaper 8-bit RAM in a system designed to use only 9-bit parity RAM. Memory errors[edit] In the 1970s-80s, RAM reliability was often less-than-perfect; in particular, the 4116 DRAMs which were an industry standard from 1975 to 1983 had a considerable failure rate as they used triple voltages (-5, +5, and +12) which resulted in high operating temperatures. By the mid-1980s, these had given way to single voltage DRAM such as the 4164 and 41256 with the result of improved reliability. However, RAM did not achieve modern standards of reliability until the 1990s. Since then errors have become less visible as simple parity RAM has fallen out of use; either they are invisible as they are not detected, or they are corrected invisibly with ECC RAM. Modern RAM is believed, with much justification, to be reliable, and error-detecting RAM has largely fallen out of use for non-critical applications. By the mid-1990s, most DRAM had dropped parity checking as manufacturers felt confident that it was no longer necessary. Some machines that support parity or ECC allow checking to be enabled or disabled in the BIOS, permitting cheaper non-parity RAM to be used. If parity RAM is used the chipset will usually use it to implement error correction, rather than halting the machine on a single-bit parity error. However, as discussed in the article on ECC memory, errors, while not everyday events, are
