What could this line be?
Recently had an issue with my computer losing power and restarting, and then later black screen of death and restarting, as well as an occasional “freeze up” where it could load web pages or YouTube before
Did the general driver repairs for a couple of months and tried to see if it fixed it, and then moved on to examining the ram, which was the case (faulty one found and ram replaced, problem solved).
I’m simply trying to examine possible reasons ram might fail after less than 3 years when I don’t overclock. One thing that I was struck by when opening it to check the ram was there was a strange stringlike substance tangled next to some of the pins near the ram, with a strong, wax feel, almost like dental floss but significantly “harder”. (The case had never been opened in the last 3 years since activation). It was of course removed when checking/testing the ram.
Could that have been shed from a ram card in some way?
