Antech Kuhler 620 Liquid Cooling System Installation help

Hello,

Here are my main specs:

Motherboard MSI X58A-GD45 USB3 SLI/CROSSFIRE USB

power supply APEVIA 800WATT POWER SUPPLY

video card EVGA NVIDIA GTX 580 1.5 GB PCI-E


processor INTEL i7-960 3.20GHZ 8M 1366 RETAIL

My stock liquid cooling system (Xtreme 120MM) was starting to make popping noises and my CPU was getting extremely hot (90 degrees C), so I did research on the product and found it was a very poor cooling system and that it needed to be replaced (i've had it for a little over a year now). I picked up the Antec Kuhler 620 and installed it . I plugged the three prong power into my four prong cpu fan slot (I researched this and found that it was ok, just to make sure it lines up correctly, but am not sure ). The computer boots normally, but it is abnormally slow/sluggish, and after running video games I get various blue screens ( they have all been different). Clearly something is wrong with the installation I did. I have done all the research on it and can't find a solution. The strange thing to is when I go into my bios i get absolutely no options (see attached photo). .

In summary the computer is running, but everything seems slow. I run stress tests and they test normally. I just get blue screens when I think it gets REALLY stressed (playing high quality video games). When I first installed it, it also was getting random blue screens and such. Anyone have any ideas for me to try, for I am sure out of them! My other idea to clarify that it was indeed the cooling system, was to unplug it, and see how the computer acts then, but was nervous about trying this. I don't have any other fans around to try.

Thanks in advance!
