I just built my first pc, so I am no expert, but I have been researching for a number of months and feel I have a firm grasp on hardware.

Specs:
i7-4770k w/ 212 evo cooler
Asus z87 pro
gtx 770
16gb corsair xm3
seasonic 650w (60 plus gold) psu
plexor 128 gb ssd
Seagate 2tb hdd

Now here's where I think I went wrong: I noticed that my RAM was running at 1333mhz in the bios instead of its intended 1600, so I manually changed it in the ai tweaker bios. Now, I really don't know what I'm doing, I merely changed one setting, which I don't think is how you're supposed to do that. The PC ran like a dream for the first day or so and then I got a blue screen, Windows has to shut down because it has detected a problem, etc. I rebooted and the computer froze again on the login screen. So I kept gettingThis kept happening to the point where I couldn't even trouble-shoot the software. So I reformatted. Then I couldn't even get through that process without a system crash, so I went back into the bios and restored defaults, reformatted again, reinstalled windows.

Well, I thought I had solved the problem, because it ran like a dream for another day. But again, I got the same blue screen and crash a couple times. I'm now running Memtest on each stick individually (already tried both together and got 0 errors.) Any other thoughts? Maybe the SSD is failing? (I did drop it on the floor when I took it out of the package for the first time.) BTW: the motherboard gives me an error code when I boot now which translates to, "legacy boot event."
Appreciate the help!

Ya, I also think the SSD is the main culprit. I'll suggest u, try a new Hard Drive or any Hard disk like from your laptop, install it in ur system, and run the system for 2 to 3 maybe 4 days. If it works fine, then ur SSD is the main culprit.
If not, then........... we'll suggest u other options. till then, try the above step.

Thanks for the reply. My CPU is idling at 35-40C. Everything in my bios is now set to AUTO as was default. I am now reinstalling windows with one ram stick to see if that makes any difference. I forgot to say, during the lockups, I would try to boot back into windows and it would give me this error, "bootmgr is missing".

When I was installing the heatsink, I got a little messy with the thermal grease (first time build), got a little on the metal CPU holder. Could that make my CPU overheat? Once I install windows, how can I test my CPU right away?

I switched out the SATA cable and tried reinstalling from the Windows CD on the SSD. On the windows installation menu it froze almost immediately.

Next, I unplugged the SSD and installed windows on my 2TB Seagate drive. All was working well and I was ready to call it on the SSD until it froze again. Upon reset, it went straight to the bios and did not recognize my HDD at all. I switched out the cable, plugged it into a different motherboard port and booted back up. Could this be a motherboard problem? Or maybe software? I'm starting to get worried.

I should add, I just realized, that a couple times the crashes occurred while I was tranferring files over a LAN from my iMac to the new PC. I have over 500 gigs of video I wanted backed up on the PC so I used a file sharing system to share folders with the Mac. It IS possible that the initial crashes occurred during transfers every single time. But I'm not sure about that.
