[Bmwpower530]

Hello everyone, i'm using my Dell e6410 for my car diag., and other automotive software. Sometimes i connect it to wifi to download big files like flashdata or softwares (50-180gb) . Often connect my phone via usb to drop files . Isuee is that Laptop always loosing usb port setup or interface drivers. Some softwares icons from desktop was gone couple times.
What can cause this issue.?

This could be a memory problem. I would run Memtest86 times. However, it sometimes happens that Memtest86 does not find any errors. therefore it would be better to try other memories. did you change the timing?
