Can you take a look at my memory dimms to see if they are compatible with my motherboard? I cannot find it.

And if they are not supported/compatible, can you do a suggestion i can buy?

[Blín D'ñero]

There's no reason to believe they are not compatible. They don't need to be on the list, because they are just standard PC2 6400 RAM.

Did you build this system yourself?

Please enlarge and fix the page file to 4096MB min and max.

-Right-click "This Computer" > Properties > tab "Advanced" > under "Performance" click button “Settings”.
- In the new window, select the “advanced” tab and click on the “Change” button of the “Virtual Memory” section
- In both the minimum and maximum spaces enter “4096” (without the quotes)
- To validate this modification, click on the “Set” and then on the “OK” button to close the box
- You must reboot your PC for these changes to take effect.

Yes i have build the system myself..

The pagefile is already set to min and max 4096

You built it yourself. Well then you should study the manual. Unlock "Auto" settings in order to tweak the system. No need to overclock, but some settings should be changed.
There is a possibility the RAM gets too low voltage at auto. In this post you said you didn't know how to change voltage. That option should become available if you open the overclock options on the CPU page (page 4-19 in your manual). Select "Jumperfree Configuration", change from auto to manual.
Proceed to Voltage Control. Change from Auto to 1.900 v. Don't change any other settings though.
FSB & Memory Config: make sure Memory Clock Mode is set to Linked; Memory Ratio to Auto; Mhz to [800]
And make sure that at CPU Configuration (Page 4-23 in your manual):
-Internal Thermal control = [disabled]
-Intel Speedstep = [disabled]

You need discussion from other users of this motherboard regarding the specific issues they encountered. Look here: https://forums.pcper.com/showthread.php?t=451059&page=3

It seems that it worked, but.. (there's always a but..) When i start my system (with the powerbutton) it doesn't do anything, but when i press my reset button the system boots, but before the POST comes, i need to press F1. I get the message that the previuous boot failed so i need to press F1 to continue booting. So, if we get this error out of the way, we're done

That is typical Asus: too high overclock/wrong settings cause F1 prompt to review the settings. Even though they often work when you manage to reach Windows, your settings apparently are not entirely correct. Review the settings, reduce any overclock.
The ON/Off button confused with Reset button: are you sure that the wires from the buttons are still correctly connected to the motherboard? Open the case and check.
Another thing you could try (worked on my old mobo) is disable the hardware monitoring in BIOS. Navigate to section Hardware Monitoring and put all fans on "Ignore'
