My specs are Asus Sabertooth 990fx mobo, 570 evga nvidea GPU, AMD fx 810 CPU, a 750w corsair PSU and ddr3-1600 ripjaws 4g ram (two sticks).

I was getting random computer lock ups and crashes while playing some games since I built this pc about years ago. It was rare but it happened on some games (CoD, Minecraft, ect.) most games ran perfectly fine.
I went about upgrade my RAM and my GPU to the EVGA nvidea 770 and G.SKill Trident X 4g (two sticks). I thought I ordered the exact same ram sticks as I had before but I didn't. I also replaced fans and put a new one in my case.

Anyway, after installing these parts I tried to turn my system on and it won't boot. All my new fans come on and my GPU fans spin and my CPU fans spin. However, I do not get any beeps at all, the lights for my disk drive do not stay on (they flash for maybe a second and then turn off) and I get no signal to the monitor.

After making sure everything was plugged in (the only thing that kind of confuses me is that the 570 has two 6 slot plugs and the 770 has a 6 slot plug and than an 8 slot plug but the cord came with two "loose" plugs connected to the wires which I plugged in having guessed that is what it was for). After doing all that I tried booting it with just one stick of ram alternating then reseating the GPU and making sure everything was in properly. Also, a right LED light is now near the ram on the top right of my mobo. I can provide pictures if needed.

After all that I put my old parts back in to see if it was a defective part that I had gotten but I still have the exact same problem. I am kind of new to PC hardware, I built this pc with the help of a friend and I have been working on figuring things out as I go but this is escaping me.

Anyone out there have any ideas? Any help? Anything would be great! I did drop a single screw on the motherboard while putting the GPU in but aside from that I always checked for static by keeping myself grounded and touching metal before putting my hands in.

Thank you so much!

Try resetting the cmos by unplugging the rig, press start button to discharge the capacitors, then remove the small button battery on the m/b for 15 seconds to reset cmos. Reinstall battery, use matched pair of ram (use original ripjaws) and reboot. If that works, shut down, unplug, discharge, swap ram for Trident and reboot. If that works, choose one matched set of ram to use.

I suspect your ram may be at different speed/settings, and cmos will not play well with differing ram.

I did some searching online and that was in fact what I needed to pull out. So I did that and had my old card in just in case something happened and it booted and asked me to hit f1 to set up bios. I just shut it down because it wouldn't recognize my keyboard anyway.

Reset again, put the new ram in and old card and it wouldn't work. However, reading the side of the ram there are differences in them. My old ram says DDR3 1600 this one is DDR3 2400 and lots of different numbers. I'm unsure what that all means, and I may have just gotten RAM by PC couldn't use.

Old RAM and new card seems to be working, it is installing drivers ect. I can update you with how it goes in a bit going to do a bit of tweaking and checking.

Thank you so much for your help! You're legendary.

On a side note just for future knowledge, How would I be able to tell what kind of RAM my motherboard can take aside from DDR3? It takes only DDR3 I know that, does it matter? Or is there just something wrong with my mobo or other ahrdware that won't let it accept the RAM?
 
Yep - a ram mismatch like that is going hose everything.

As far as selecting ram for your m/b, if you pull up you board on the Asus site (HERE) and look through the specs, it will tell you what speed(s) it can handle natively. You can certainly try to o/c the ram, but that's an entirely different animal. Your specs say the m/b can handle up to 1866mhz ram, and when you tried to run the 2400, you board bios was unable to handle the task.

Glad you got it running.
