Overclocking problems with i5 3570K in GA-Z77X-D3H

Hello everyone,
I will list my specs first:

CPU: Intel i5-3570K
MOBO: Gigabyte Z77X-D3H
RAM: 2x 4GB Kingston [KHX1600C9D3/4G 4GB 512M x 64-Bit DDR3-1600] **At 1.65V 9-9-9-27-36

GFX: Nvidia Msi GTX 660ti
HDD: 128GB Corsair SDD
CPU Cooling: Corsair Hydro Series™ H70 (Watercooling)

Everything runs completely stable at default speeds. I have tested overclocks without changing default RAM settings and still experience the problems listed below... so I'm not thinking it is the RAM...

1) When I try running overclocks I am able to pass the following stress tests: Prime95, wPrime, Battlefield 3, any other 3D Game, without any problems at all. After the PC has been running for at least a little bit, I continuously run into random problems with programs. Usually an .exe will just not open up when clicked, followed by the inability to open task manager or shutdown/restart/logout the computer. At this point, opening other programs usually work, but its always one application that randomly stops responding and nothing can be done until a hard restart.

2) Everytime I am forced to restart, and also during other times, the computer freezes at the Gigabyte boot logo screen. The only way to boot up past the logo is to completely cut all power by switching off the power supply switch and back on.

Overclock settings that I've tried, and still experience the same problems:
- CPU Base Clock: always at 100.00Mhz
- CPU Clock Ratio: 4.5Ghz
- VCore: 1.25V-1.275V reaching max temperatures just under 70deg celcius with Prime95 on RealTemp.
- Disabled Turbo Boost, C1E, C3/C6, CPU Thermal Monitor, CPU EIST Function
- Load Line calibration: Turbo

I've also tried these settings:
- CPU Base Clock: always at 100.00Mhz
- CPU Clock Ratio: 4.5Ghz
- VCore: set to "Normal", Dynamic DVID set to 0.17V, reaching max temperatures of 67-75deg celcius with Prime95 across cores on RealTemp.
- Enabled Turbo Boost, C1E, C3/C6, CPU Thermal Monitor, CPU EIST Function, and increased Power/Watt limits to 250

I've also tried decreasing CPU PLL to 1.65V but im not to sure what this does.
**Monitoring with CPUID CPU-Z, I get VCore voltages of 1.304-1.368V when using the DVID offset--shouldnt it only go to a max of 1.27V if Dynamic DVID is set to 0.17V / VCore 1.1V?

Can anyone help me get running stable at atleast 4.3-4.5Ghz?

* EDIT: Test results

- Memtest86+ v4.20 passed all successfully when ran for 11hrs

***UPDATE: Check this picture of the inside of my PSU. I noticed that there is some hard white globs of stuff on the board next to some components. I'm not sure if its just glue/cement. My PSU seems to be making a very faint high pitch noise only when the PC is shut off, it is immediately gone as soon as power is on.
