Thread starter reported a Windows "NMI: Parity Check/Memory Parity Error" on a DELL DIMENSION E520. That message is a hardware-level NMI (bugcheck 0x80) indicating a parity or memory-bus error rather than a plain software crash; Microsoft's bug-check notes list memory subsystem and related hardware as common causes ().

Practical diagnostics (in order of effort/impact): collect evidence first — check Event Viewer (Windows Logs → System) for NMI or memory-related entries and save crash dumps. Run a bootable memory tester such as MemTest86 and let it complete multiple full passes; errors that follow a specific DIMM point to a bad stick, while errors that move with a slot point to a board/slot fault (MemTest86). If tests are clean, the fault can still be intermittent; repeat tests after leaving the machine powered down and cooled.

Other useful steps: run the vendor pre-boot diagnostics, boot with the minimum hardware fitted, update BIOS/chipset drivers, and try known-good memory if available. When cleaning connectors use non-abrasive methods (compressed air or high-purity isopropyl alcohol and a soft brush); avoid abrasive rubbing that can remove plating. If memory faults persist after isolating modules and slots, suspect motherboard or power-delivery faults and escalate to service.

Because later noted the problem was resolved, document which exact action eliminated the error and keep test logs for future reference. Reference links: Microsoft bug-check details, MemTest86 downloads/instructions, and Dell support home for device-specific diagnostics (Dell Support).

I solved the problem I remove all the device installed on my PCI Slots.
Then I clean with eraser all the pin of modem and wireless PCI device.

Hope it will helps others too...:-)
