I have had this computer for a week or two, and it has not had any problems so far. It came with a 150gb ssd and I wanted to upgrade to more storage, so I installed two new hard drives. After installing the second 1.5tb hard drive the computer worked fine, it was after installing the 320gb hard drive from my old computer when the problems started happening. I'd plug in the sata cables and everything but when I'd turn it on it would be stuck at the windows 10 logo. I don't know if it is a problem with windows 10 or if there is a problem with the hard drive, anything helps though. Here are the specs of my computer:
Intel Core i7-3820 CPU @ 3.60GHz, 34Gb of ddr3 ram, NVIDIA GeForce GTX 960 (PNY), 149GB INTEL SSDSA2M160G2GN (SSD), 1397GB Seagate ST31500341AS (SATA)
