Computer hardlocking when under stress

[Dilbrav]

Motherboard: GA-Z77M-D3H-MVP
Processor: Intel(R) Core(TM) i7-3770 CPU
Graphics Card: AMD Radeon HD 7870
OS: Windows 7 64-bit
RAM: 4x4gb Corsair Vengeance
PSU: 750Wat NAXN
120g SSD - Running OS (another: 60gb ssd/1tb/ and two 300gb)
Cpu Cooling: zalman cnps10x

Basically running a game like GTA V will cause my computer to hardlock anywhere between 15 minutes to a few hours so that it needs to be hard reset by the button. Running prime95 blend will also cause it to lockup within 5 minutes.

I've reinstalled my os and drivers and replaced my video card and I've run my os from another hard drive. I don't think a problem with overheating as it locks up when the core temps are ~70c and my video card doesn't go much higher than 70c itself.

The voltages shown in HWmonitor are a bit wonky but that may be because of the sensor, the voltages in the bios seem ok.

I haven't run memtest86+ yet as I don't have any usb sticks around but I've run through each stick 1 by 1 and it still occurs (timings are voltages are right, occurs on both 1333 MHz to 1600MHz)

Whocrashed doesn't show anything and Event viewer shows some things but I'm not quite sure what to look for, -will lock it up again and cross reference the time it occurred at with the error and attach an HWmonitor "screenshot".

Thank you for any help, it is greatly appreciated.

Update your BIOS, make sure the vcore is normal on the 3770 and make sure ALL CORES are NOT turboing to max turbo speed.

Should I download the F8 version?

The turbo settings in the bios are all set to auto, I can disable that all and try locking it up again.
My Vcore in bios is also 1.164V not the 1.068V it shows in HWmonitor.

Yes 1st go ahead and install the F8 BIOS.

If that doesn't fix the problem, then manually set core 4 to the lowest setting then set the 1st core to the highest turbo setting manually.

I've been running prime95 so far since disabling the turbo and it hasn't locked up yet and I don't think it has run this long before so I think we're on the right track.

Thank you for your help so far

---I can the either Enable/Auto/Disable the Turbo boost Intel (R) option but I can't manually change each of the cores first is automatically at 39 and the fourth is at 37.

if it's 39 then down to 37 that's where it should be.

Have you tried the F8 BIOS?

When I download and extract it I get "the program or feature cannot start or run due to incompatibility with 64-bit versions of windows" when I run the autoexec.bat , unfortunately I don't have usb around to try update it from that.

Does the turbo boost produce a noticeable fps difference? The cpu clock ratio is locked at 3.6 but if I change the view to simple from advanced I can change it up to 4.2.

Alright so after testing my computer out it still freezes even when turbo boost is off and the clock is at 3.4.

Under the warning tab in Event Viewer I had this come up around the same times as the lock ups

The driver \Driver\WUDFRd failed to load for the device WpdBusEnumRoot\UMB\2&37c186b&0&STORAGE#VOLUME#_??_USBSTOR#DISK&VEN_GENERIC&PROD_USB_CF_READER&REV_1.01#058F312D81B1&1#.
