One thing you could try doing is creating a bogus partition of 50% of the drive size and then installing Windows onto the NEXT partition, i.e., forcing Windows to install to a different logical location. I say logical, because drive circuitry provides an abstraction nowadays anyway so it is anyone's guess as to where the bits are actually being stored. At least this may provide some sort of indication that it is indeed the hybrid drive, if that suggestion works.
I would be looking at memory though initially, but you say it is fine?
Perhaps run a disk test utility of some sort against the SSD. Also try replacing the SATA cable for both DVD drive and SSD (if you've just done one..) and ensuring mobo is at BIOS default and on latest firmware.
