Small update and adding something I just thought of.
Was able to run Memtest86 from a CD for 3 full passes, took about 1 hour and 50 minutes total, but it said 0 errors. This is only with the single stick of ram currently, So I guess i need to either try it with the other stick in the same slot, or would it be better to first try this same stick, but in the other slot? Currently its in the more exterior socket.
Also I recall that my laptop battery if running from full charge and without wall power will only last me like 1 hour at best with basic web browsing or maybe even just idle. I assume battery degredation over time is normal, maybe not this much though... either way I am now wondering again if the battery could be a problem causer since again as a reminder, I am currently running it purely off the wall power with the battery removed.
Hopefully someone can chime in soon to aid in my troubleshooting or even an outsider at least comment that I am on the right track to try all of these things, I hate to be wasting countless hours on things that might not be worth it or are too small of a change to narrow it down.
Thanks.
