BSOD playing Sims Medieval and when streaming TV or dl win updates

when i try to download prime95 the download keeps timing out. Help?

Try downloading while using a different system. You may also need to check your firewall settings.

I've ran the memtest for four passes and it has come up with 144 errors so far... The third part of the tutorial you linked to talks about testing RAM sticks and slots. This involves actually opening up the laptop correct? I've never messed around much with the insides of my machine before. I don't want to mess stuff up more and I don't think I have the right tools. Any advice on how to proceed from here? Thanks!!!

Halfway though pass six and it jumped to 222 errors.

Is the laptop still under warranty?

If so, have it serviced by Samsung.

If not, just do your best to get grounded (find a metal door knob that you know will shock you if you have ESD built up, and move your laptop close enough to the door to touch it prior to working on the inside), remove the bottom panel associated with upgrading RAM (see your system manual), and follow the instructions in the Memtest86+ tutorial.

Turns out I had a bad memory chip! Replaced it!
