So recently after experiencing plenty of BSoDs and freezing with my PC, I ventured into the bios to try and change some of my overclock settings. While in the bios I first set the RAM voltage to automatic. Then I noticed that the ram was set to 800Mhz, so I thought "my DDR3 ram is 1600, that must be wrong!" so I changed it to 1600, and restarted the PC. When I tried to turn it on, all fans and LEDs turned on, but my monitor, mouse and keyboard didn't do anything, and I am now unable to boot into the BIOS and reverse the settings. PLEASE help with any advice! I have already tried removing each ram card, and trying them in other slots, but that did nothing. I also tried disconnecting the power cable for a few minutes, and then replugging it and trying, still nothing.

specs:
AMD Phenom ii x4 965 processor
Nvidia GTX 780
500W psu
DDR3 1600 RAM (2x4 GB)

let me know if you need any other spec info!
