So before you start reading: I know this is a enormously long text, but I wanted to provide all of you with as much of information as I could. PLEASE help me because this is a SERIOUS problem to me.
I will be super thankfull for all responds/answers that even help me out the slightest thing.

Hey there, thanks for reading my question, a pretty hard one in my opinion even. You'll be my absolute hero if you help me to fix it : )

Problem: The system won't boot, in fact it doesn't even post.
What works: I do have installed ROG Connect on my laptop and it works as far as I know.

Signs: The Q-Code is 50 (this code relates to DRAM problems, google is your friend)
LEDVGA keeps being lighten.
ROG Connect poster says: "Detect Memory", I also saw that the memory speed was 1334, instead 1333. That could be a problem since I believe my AMD Phenom II x4 BE supports up to 1333 and q-code 50 includes "too high frequency", or some alike problem. But, I wouldn't think 1hz would cause the problem...

So, what happened:
I came home after a wook or so, I wanted to boot my system but I instead went to the BIOS with the direct key, because I wanted to get rid of the option ROM message.
I remember I changed some tiny thingd (nothing to anything that has to do with RAM) like the fast-boot options, I also changed the option rom option form "Force BIOS" to "Keep Current", I did get rid of the option rom screen but didn't get a splash screen. But when Windows started booting, after the boot animation, I got a BSOD, I remember it to say something like: "bad_system_config_info" and at the bottom some numbers of wich I could do nothing with because it disappeared way too fast.
I got pretty scared because I've never had a BSOD on the pc ever before, I NEVER had any real, serious, problems with my quite new-build rig ever before and it always worked perfectly for me. Anyway...

So I reset the BIOS settings to default optimisations and rebooted, same thing happened.
When I ran Startup Repair, it couldn't find a solution, but in the advanced info of the message it wanted to send to windows' help desk or something, I remember it stated something with the memory.
I already thought it COULD be something with the RAM because problems like these usually have to do something with the RAM.
What I did because of that was like most people do to check if a RAM module is corrupt/broken: try to boot the system with only one RAM module and trying a different module everytime. I even tried it with no ram installed, the same thing happened (q-code 50)

(I have 2 Corsair Vengeance LP 2133 modules together with two other Corsairs of wich I am not sure what they are... The CPU is a AMD Phenom II x4 3,4Ghz BE, I know, bad decision)

But Every module ended up with the same thing, nothing different. I though it would be pretty weird if all four of them would be broken, but I kept trying. I tried resetting the BIOS settings multiple times again and again but it didn't help. After a while, even something worse happened. Where I am now, the only thing my rig does is turning on some lights on the motherboard (Like I said, the LEDVGA and the q-code is 50) but no splash screen or whatsoever, no posting at all.


What I've already tried/done:
I've read and searched for quite a lot of forums on the q-code error, it appears to be an error about the DRAM, errors could be: Too high ram speed, incompatible ram etc. etc. Ofcourse I haven't read every forum page at the highest detail, so that might be an option for you if you want to read some of them (again google is your friend).

I tried to completely reset the BIOS by removing the battery and placing it back later, I even removed it and only put it back atleast 45 min. later without any source of power connected.

I removed every single component except the PSU and the CPU... Ofcourse I also had different RAM modules in it.

I DID think about RMA of the board, but I don't know exactly how long that will take since I live in the Netherlands (though I did buy it at a Dutch/Netherlands shop with warrancy). But again I don't know how long that will take and I need it to be back and working before the 6th of July (then I have a planned LAN-Party with some of my friends :) ). Also I am still not sure exactly wich component even is the problem: the vengeance RAM or the

I haven't tried updating the BIOS YET, but I don't even know how that exactly works since I have never done it before.

To round it up:
I would absolutely love to atleast have you to tell me what you think/know the problem is, and if you are awesome enough know the best solution...
Ofcourse I prefer the most efficient way of solving it, keep in mind I'm just a teenager who knows a frickin' lot of pc hardware etcetera.

Again, thanks for ALL comments I can get, yet again, this really is a serious problem to me. Since I am on a pretty tight budget (you know, I am a teenager after all).

Here is one thing I have had some luck with solving this problem when my ROG motherboard won't boot and is giving me a 50 q code. I'm sure you'll get much better, and most likely completely antithetical, advice from other people on Tom's Hardware.

So, when this happens, I have to go into the BIOS and give the DRAM voltage a few extra knocks on it's tally. i.e. Up the voltage enough that your machine will boot, then afterwords go back into BIOS and bring that back down to acceptable operating levels.

Last time this happened, which was last night and also why I found this question, I had to boost the voltage from Auto/5.5 to 6.5-7.0. When I got it to boot again, I went back in an put the voltage to about 1.6.

Take that advice with a grain of salt. ... Like, The Dead Sea amount of salt.

It turned out I must have not cleared the cmos well enough, I removed the motherboard's memory battery and left it out for a whole night. After that it all went well...
