Hi guys, first time posting here so forgive me if I do anything wrong.
So, about a week ago, my computer stopped turning on suddenly. I called in a repair man/tech and he said it was my power supply. Since he replaced it with a new one, all of my games have been suffering crippling lag. I used to be able to run games like BF3 on max at plus 60fps smoothly, but now I cant even play RO2 on the lowest settings above like 5fps. Almost every game is like this. Could it be the new power supply? Or is it just coincidence. Here are my computer specs.

Windows: Windows 7 Home Premium Edition (64-bit) Service Pack 1 (Build 7601)
Internet Explorer: 9.11.9600.17126
Memory (RAM): 16296 MB
CPU Info: Intel(R) Core(TM) i7-2600 CPU @ 3.40GHz
CPU Speed: 3391.7 MHz
Sound Card: Speakers (3- Logitech G35 Heads |

Display Adapters: NVIDIA GeForce GTX 680 | NVIDIA GeForce GTX 680 | NVIDIA GeForce GTX 680 | NVIDIA GeForce GTX 680 | Intel(R) HD Graphics | Intel(R) HD Graphics | RDPDD Chained DD | RDP Encoder Mirror Driver | RDP Reflector Display Driver
Monitors: 2x; Generic PnP Monitor | Generic PnP Monitor |
Screen Resolution: 1920 X 1080 - 32 bit
Network: Network Present
Network Adapters: Realtek PCIe GBE Family Controller | Hamachi Network Interface

As of now, the guy installed a cooler master EXTREME 2 725 power supply. Before, I was using a corsair 850w. If you guys need any more information, just tell me what you need.
 
Solution
Check the cables. Make sure that the monitor is plugged into the graphics card and not to the motherboard. Check the graphics source selection in your BIOS. It should be designating the PCI Express x 16 slot not integrated.

YEP turns out I had my monitors plugged into the wrong ports! Thank you for your speedy replies guys!
 
Look at the back f the PC. The graphics card is mounted in the expansion slots. The motherboard graphics outputs are in motherboard input/output area (along with the audio outputs, network ports, ect.). Check your motherboard manual for illustrations. The monitor cable needs to be plugged into the vertical graphics card

Do you know how to enter the BIOS? This video may help.
