Unknown hardware issue

[tipoli]

Hi,

I have a laptop Dell Vostro 15 3500:
8GB RAM 2666 (2x4, one stick that already had on it and other from Crucial)Intel® Pentium® Gold 7505

Recently randomly the laptop frozen and nothing works with artifacts on screen like a video crash.

On windows event visualizer I found a lot of warning messages with "A hardware error was fixed" with Microsoft Windows WHEA-Logger ID 17
Component: PCI Express Root Port
Error Source: Advanced Error Reporting (PCI Express)
Main device: PCI\VEN_8086&DEV_A0B0&SUBSYS_0A241028&REV_20

*I've translated some of these messages because my system isn't running on English

Bios and drivers was already updated with latest drivers downloaded from Dell website, but this crash is happening from some months and nothing of this works.
 

Now running using:
Intel(R) UHD Graphics version 31.0.101.5186
 

Someone can point a way to diagnosis better this problem?

try with just one stick of ram, then with just the other.
