Ok, I am 3 days late for this. Do you still have computer issues? Sadly enough, you already ran CHDSK before securing the SMART data of the disks, so I cannot determine for 100% if it's your harddrive anymore. However, if you're still having problems: download this and post a full screenshot as shown here. Especially make sure you capture everything that is in the scrolling part of the window on the lower side.
As for memtests, you could consider running Memtest86, which can be found here Be sure to follow the instructions from the technical info page. Also, do note that it's important to give the memtest sufficient time to run on the membanks. It's common to run a memtest for a whole evening on a single bank.
Good luck
