I recently built a new computer but got sent a bad PSU and after about an hour it died. I sent it back and got a new one that has been working just fine, but i noticed some odd problems with they way my computer was running, and then after restarting the smart status of my hard drive indicated its status was bad. So i sent it back but am currently waiting on a replacement. My friend gave me memtest to test the status of my RAM to see if there where any problems with it. I tested the first stick and got an Unexpected Interrupt - Halting CPU0. I then ran the second stick and it passed, i assume that my first stick is bad but am not entirely sure. I also do know if this could be all related to my PSU dieing.
