Your symptoms CAN be caused by ram that is NOT 100% compatible with using it in your mboard. In some cases, you get no video, no error beeps, the mboard will not boot.
As far as I know, you CANNOT get the error beep pattern indicating no ram is installed if the mboard isn't recognizing the cpu !
To make sure the ram is going to be 100% compatible with using it with your mboard, you should use a ram configurator or similar program to look up which module part numbers are listed for (= are compatible with) your mboard model.
Corsair Memory Finder
NO LISTINGS FOR GA-Z68AP-D3 !!
However, if you search using a similar model that has the same main chipset, the ram that is compatible with that model is probably compatible with using it in your model.
E.g. Search using GA-Z68XP-D3
There is a short list of recommended modules, and a link you can click on to show a much longer scrollable list of all the Corsair modules that are compatible with the mboard model.
The Corsair part numbers for the modules you bought MUST be in that longer list.
You could also look at the list of ram modules Gigabyte has tested with the mboard model to see if the ones you bought are on that list.
Apparently there are two Revisions of the GA-Z68AP-D3 model's board - 1.0 and 2.0 - That's printed on the surface of the mboard - it's often right next to the model number, but it may be elsewhere on the mboard's surface. E.g. R 1.0 or Rev 1.0;
It may be 1.x or 2.x, x being a number higher than zero.

If the memory you bought is CONFIRMED to be compatible with your mboard......
Flashing the bios is the riskiest thing you can do with a computer !
If flashing the bios results in the mboard will NOT boot normally after that, the mboard's warranty DOES NOT cover that !
You do that AT YOUR OWN RISK !
If you don't want to take that risk, buy a cpu the bios version already supports !
The bios version the mboard presently has MAY be shown on the label on the box it came in, but I've never seen that. There is usually if not always NOTHING printed on a stuck on label on the mboard that indicates what bios version it has, even on the bios chip.
There may be a date the mboard was manufactured on that label. If so, the mboard cannot have a bios version on it that was first released after that date.
You may be able to contact Gigabyte and provide info on that label to have them tell you which bios version it has on it.
Usually when the mboard's present bios version can't recognize the cpu you installed because the bios version is not new enough, the mboard still works with that cpu but the bios uses fail safe default settings for the cpu. It's quite unsual these days for the mboard to not boot at all in that situation, but that's possible in theory.
Are you SURE the CPU is all the way down in it's socket ?
If you're not sure, remove the heatsink and make sure. It wouldn't hurt to try releasing the socket lever, then latching it again. In rare cases that may fix youir problem.
Assuming your mboard's present bios version can't recognize the i7 3700 cpu and because of that the mboard won't boot and you need to update the bios version, you could either
- buy the cheapest cpu listed for your mboard that you can easily find locally, install it, flash the bios, remove that cpu, install the i7 3700 cpu
- take your mboard to a local place that works on computers and has a suitable cpu the mboard already recognizes fine and have them do that without you having to buy a cheap cpu, for a fee
You MUST know which Rev your mboard is in order to flash it with the RIGHT bios update. The bios updates for the two Revisions may be DIFFERENT.
You must use a bios update that is listed for your specfic Rev of the mboard model !
