Was this the latest version of memtest?

That is worrying. The things I would look at first are that the system
firmware is totally current, and that the PSU is known good and rated
high enough to drive all your compoennts.

Which kind of firmware does your motherboard have?

Yes you can.

I don't know what you did but that is not right. If you pick
"something else" you can put whatever you want wherever you want.

You say the HD is 3GB. I think you mean 3TB.

That means it must be partitioned with GUID -- that is too big for MBR.

I advocate very simple partitioning schemes.

E.g. if the SSD is /dev/sda and the HD is /dev/sdb, then:

/dev/sda1 : single primary partition, default filesystem, as /
/dev/sdb --
  /dev/sdb1 : one big /home partition,
  /dev/sdb2 : on the end, a small swap partition with 2 x physical
RAM. You won't need this much but with 3TB you can afford it.

(With GUID there is no distinction between primary, extended and
logical drives any more.)

That's not right, though.

Yes.

No. Doesn't matter at all.
