Can't boot to windows after video card crash without removing USB
As it says in the title I get this weird issue where occasionally when playing specific games my monitor goes to a black screen with the last second of sound looping which forces me to power off the PC then restart it.
Now when I restart it will progress beyond uefi boot and show the Windows 7 loading screen for a second or 2 but then freeze and the only way I can get my PC to boot to windows after that is another hard shutdown and restart having removed 2 USB cables from my motherboard. I don't think it's a driver issue as I have removed USB's connected to various devices and just regular USB - mini USB/USB - iPod cables, I've always just removed a pair from 2 of the top 4 USB slots so I couldn't tell you whether the removal from the lower slots or just removing 1 would also allow me to boot into windows.
I'm confused because the USB and Graphics card are 2 wholly separate entities to my mind, so I'm wondering if perhaps this could be due to an unstable overclock?
My stats are:
CPU - Sandy Bridge Core i5 running at 4.9ghz Mobo - Asus Maximus IV Extreme (P67 revision B) Graphics card - GTX 570 Point of View Beast edition Ram - 16GB GSkill at 2133Mhz (reference speed and timings) PSU - Corsair TX 950 watts
Please let me know if you have any ideas or require me to run any tests/provide further information.

Most likely an overclock problem. Run at stock settings and see if issue is resolved.
