My system was built in November of 2011.
Asus Maximus IV Extreme Z
I5-2500K processor
Corsair H100 AIO
8 GB Corsair Vengeance 1600 mhz 1.5 volts 9-9-9-24
Corsair Force 3 128GB boot drive
Asus Strix GTX 780 6GB
Windows 10
running latest BIOS on motherboard.
Everything was running fine until yesterday a friend gave me 12GB of 2000 mhz DDR3 for free.
I removed my (4gb x 2 )vengeance 1600 mhz sticks and put in two of the 4GB 2000 mhz modules in the correct spots. It wouldn't boot so I went back to the original RAM to trouble shoot. The monitor kept saying NO DVI. The screen was blank. I tried clearing the CMOS and used the MemOK button to reset the RAM to default. I took out my GTX 780 and tried my spare GTX 750ti instead. I was able to get into the bios on default settings and clicked save/restart. Now the MOBO is giving me error code B2 (Legacy bios) which I don't know what that means. It's also not seeing the boot drive anymore. I can't get into the bios anymore no matter how many times I press delete on the red Asus splash screen. After 2 minutes or so the screen goes black and i see a white blinking cursor on the top left of the screen.
I know my GPU's are both functioning. I had them both running 3 days ago for the past 4 years I've owned them. The GTX 780 is my primary card, the 750ti is the PhysX card only.
During this trouble shooting I only have 1 card installed. I've checked all the cables and power is working fine.
Please advise what I should do. I've been rebooting over and over for the past 2 hours and my system is not booting into windows or letting me get into the bios. I've tried 2 different keyboards and nothing. No other USB devices are connected but the keyboard and mouse.
