OptiPlex 390 Diagnostic Errors

[SAgosto]

I have an old OptiPlex 390 that is failing to boot. I ran F5 diagnostics and getting a ton of errors:

2000-0415 - Intruder Switch Cable
2000-0114 - CPU - Cache Integrity test discrepancy - TON of these for CPU 0-4
2000-0122 - Memory errors detected. Limit exceeded

Too many odd errors leads me to believe board/CPU/etc. is f0ked.

Thanks. This is what I assumed.

For intruder switch, disable intrusion detection in BIOS.

For the other two errors, really bad memory can cause that. You can try pulling the memory sticks and cleaning the pins and reinstalling them. It's a common issue on garbage tier memory Dell uses.

this might explain why I can’t boot to usb for win install

thats how our failures started to show, failed usb ports, then random error, then locking in bios etc etc etc.

That era of dell was always the power supplies or the RAM. The PSU would start acting flaky and cause the machines to act weird. The RAM was another common failure, thanks to Dell using bottom of the barrel garbage sticks.
