So here is my rig:
CPU: Intel® Core™ i7-3820 Quad-Core 3.60 GHz 10MB Intel Smart Cache LGA2011 (All Venom OC Certified)

MEMORY: 8GB (2GBx4) DDR3/1600MHz Quad Channel Memory

Motherboard:SLI/CrossFireX Support) MSI X79A-GD45 Plus Intel X79 Chipset Quad Channel DDR3 ATX Mainboard w/ Winki 3, OC Genie II, 7.1 HD Audio, GbLAN, 3 Gen3 PCIe X16 & 4 PCIe X1
I had one: EVGA GeForce GTX 770 DUAL SuperClocked 2GB 256-bit GDDR5 PCI Express 3.0 SLI Support w/ EVGA ACX Cooler Video Card 02G-P4-2776-KR

And i tried to SLI it with another same exact card.

my power supply is: Cooler Master Silent Pro Gold - 1200W Power Supply with 80 PLUS Gold Certification and Semi-Modular Cables

so like the the title says I am now getting three beeps when i try to turn on my PC. the PC turns on and stays on but there is no display. the pc was running fine until i tried to SLI and now it make three long beeps when i try to turn it on. any help would be appreciated.

hey guys thanks for the replies, well it appears that it was the memory but it was operator error. I am new to PC building and i was too gentle pushing the ram sticks down, they work fine now.
