XPS 15 9510 PCI Subsystem Failure
Hi. I bought my XPS 15 9510 in May 2022 and it ran great until a few weeks ago when it started to randomly freeze. I ran the Dell diagnostics and the only failure is the PCI Subsystem. Is this a software or hardware issue? What are the common fixes? I used the virtual tech support which ultimately directed me to contact Dell however I live in Saudi Arabia and have been unsuccessful in speaking with a live technician nor have I received a reply to my electronic query.

Did you run the Dell diagnostics (F12 at powerup) or Support Assist (the latter is under Windows and well known for false positives)?
Run the hardware diagnostics by pressing F12 a few times at powerup. Any errors: record by number (2000-0142, etc.) AND the validation code. Then contact your seller for assistance (all support there is handled through your dealer).
If no error arises in the hardware diagnostics, you can safely ignore what was reported by Support Assist. Freezing is more often caused by software issues than by hardware failures.
