Firstly, my rig (in order of relevance to subject):
i7-4770k
Gigabyte z87x-ud4h
Cooler Master V8 (not the new one)
G. Skill Ripjaws X 2x4GB 1600 MHZ RAM
Rosewill Capstone 550w Modular PSU
GTX 770 Gigabyte Windforce Superclocked w/ 4GB Vram
Seagate 1tb SSHD
Ok so I did a lot of research into overclocking, because this is my first overclockable PC. At first, I tried just changing the multiplier to 42 and leaving the base clock at 100 to see if it was stable. I played hours of intense games (Far Cry 3, BF4, BF3, Skyrim, etc.) I then ran Prime 95 while monitoring temperatures. It did not find any errors and no blue screens, and temperatures did not go above 145-ish Fahrenheit. I looked at CPU-Z, and everything registered correctly. So then I turned my computer off for the night and went to bed. When I turned my computer on, before POSTing it turned off restarted and after POSTing gave me a message that there was an error starting, and that it loaded optimized defaults. I then could go into BIOS do what ever overclock I wanted and go back into Windows 7 Ultimate and never have a problem with my testing. I tried an overclock at 4.4 ghz, 3.9, 4.1, etc. All of them were stable, although the same problem kept presenting itself when I tried to turn off and then on. I even tried following Intel God's quick and dirty guide to Haswell over clocking. It did not change anything. Only other thing to mention would be that before I started attempting to OC, when I would shut down from Windows, the fans would remain on, but when I overclock and shut down they turn completely off.
