After in stalling 8GB more (2x4GB) RAM, my computer won't boot. Everything seems to be normal but nothing shows up on my display. My graphics card's fans stop and go and keep repeating this. After removing the last stick of RAM in the 4th slot, the computer boots. It is not the RAM because I changed it out and it still won't boot with it in the 4th slot. I tried resetting the CMOS and upping the voltage in the BIOS but nothing is working. The 2 different sets of RAM run at different speeds. The new set runs at 1866 and the old one 1600.

Are you sure that you're putting the two speeds on different channels? They are often color coded, put all of one speed on one color, and all of the other speed on the other color slots.

Okay, take all of the RAM out, then turn the machine on and back off after thirty seconds. This will reset the memory controller.
Next, try the RAM one stick at a time, try booting with one stick being the only one in there at a time. Reboot each time you swap out a stick until you've tried each stick individually. Use the slot closest to the CPU.
Next, start with the slowest RAM, one stick in the slot closest to the CPU. Then add the other one of the same speed to the other slot of the same color. Try to boot each time.
Next, start adding the faster RAM, starting with the empty slot that's closest to the CPU. After confirming it works with one stick, put the other in the only remaining slot. If it doesn't work after adding the first stick, try putting the other stick in its place. Try booting again. If it boots now, then put the remaining stick in the remaining slot and try booting again. If it again won't boot, then the last stick is faulty.
If it simply won't boot when you add the second speed, then they are not compatible.

I got to the part where I added the first stick of faster RAM and it boots. Then I added the second stick and it doesn't boot. I swapped them and it didn't boot and I also swapped them with the slower speeds and it doesn't boot. It just doesn't boot when there's one in the 4th slot.

But any arrangement of any sticks in the other three slots works? Of course, staying with one speed per channel.
If it's the fourth slot that stops you every time, regardless of the rest of the setup, then you have a bad slot. Is the motherboard under warranty?

Press Win+R to open Run, type in msconfig, press Enter. Let me know everything that relates to RAM.
The only thing I found that relates to RAM is the option to check Maximum memory and it isn't checked. Wouldn't this be a graphics card problem though? Because the graphics card isn't powering on or displaying anything once the RAM is inserted?

I'm sorry, I told you to open msconfig... I meant msinfo32. Try that instead of msconfig
Sorry mate

What is the total capacity of the three sticks you have installed? Surely it's more than 4GB, right?
Please try shutting down your computer, unplugging it, pressing and holding the power button for three seconds to drain any remaining power, opening up your chassis and removing the CMOS battery from the motherboard (looks like a large watch battery). After thirty seconds, put it back in, put everything back the way it was and try again. After it boots up, report back with what msinfo32 has to say about RAM.
If it shows more than 3.96GB (was 4GB before formatting), then try my steps with the RAM sticks again.
If it continues to show only 3.96GB total, then we have a problem that needs further troubleshooting. Either way, I'm going to bed. I'll be back online tomorrow.

What are the model #s of the sets of DRAM, the mobo and the CPU? There's no guarantees when mixing sets of DRAM, depending on the hardware we can try making some voltage/timing adjustments to try and get them to play

Are you sure you're running a 64-bit version of Windows?
Press Win+E to open My Computer, and navigate to the root of the C:\ drive. Is there a "Program Files" folder and a "Program Files (x86)" folder? If there's no x86 folder, then you're running a 32-bit version of Windows, therefore your computer can only interface with 4GB at a time.
