Aurora R12, Diagnostics, PCI Subsystem failure
Alienware Aurora R12
Hi all,
I would just like your help with an issue I have just been told I have. I have just run a Diagnostics test. It has come up with a PASS on everything except a PCI Subsystem category PCI Bus failure. I was just wondering if anyone could help me with this matter?

If everything is working, sounds like a "false positive" to me.

The psa testing on pci is very vague. Any real mobo problems is most likely to appear in the device manager.
I take these tests with "a grain of salt" as the old saying goes.
As an example ,not long ago I ran psa for a memory check. At one point a little pop window with an OK button appeared saying a "correction was made" click ok so test finished all ok no problem.I did not know that the psa made corrections but the psa said ok. So I ran the window memory and memtest86 tests and both showed problems very quickly even even after reboot. Memory parameters looked ok.

what about preboot supportassist on your pc, another Dell AI? If that passes everything, the online Dell dx test has a bug.
one user reported "I'm running Online Diagnostic test and I have one error which is PCI Bus Subsystem. But when I run the pre-boot diagnostic test it says that all passed."

Noticed this as a reported issue on some other systems also, yet the systems seem to function fine.
It looks like this might be related to a BIOS problem rather than a hardware issue and will likely resolve itself with the next upgrade cycle.

Did you check device manager for any obvious trouble ( yellow flag) ?
