I already tried to take the battery out for 10 seconds and putting it back to reset bios. Didnt help.
You may like to try the following.
With the PSU switched off. Take anti static measures by briefly touching a bare part of the case. Look for the clear CMOS jumper on the MB, > move the jumper over, leave for 5 seconds, > move back to normal position, > switch on the PSU. press start button.
Keyboard lights dont flash. I dont have a slot for the speaker in my motherboard. I also dont think that it could be ram cause adding wlan card shouldnt have anything to do with ram. But with a possibility that the ram broke with the motherboard.
Without a display it is very hard to perform a diagnostic.
If when you press the start button, the lights on the keyboard flash, this indicates the BIOS has started to POST, but not reaching the display, a component or part of the MB is damaged or not seen.
If you do not have the user manual, to download go, > http://www.asus.com/...LM_LX3/#support
You have not reported hearing any beeps, so looks like you do not have a System speaker installed like this, > http://www.cwc-group.com/casp.html, page 23 of the user manual.
If POST is not successful, you will hear a beep code which can give an indication of what is wrong. Codes are in the MB manual.
Before replacing any parts, I would install a speaker, test and post the results, It could be the RAM damaged, not the board.

Please see the attachment below.

Partially correct but if the MB has been shorted out in any way each component that was connected to the MB at the time may also have been damaged.
I also dont think that it could be ram cause adding wlan card shouldnt have anything to do with ram.
I concur with iammykyl and suggest that you obtain a BIOS speaker for testing purposes (see second attachment) follow the previously advised safety steps, connect the BIOS speaker, remove the Ram, reassemble the computer (minus the Ram) turn on the power and let us know if you get any error beeps, if you do it suggests that the Ram may be bad, if you get no error beeps it suggests a problem with the MB or an outside chance the PSU.
But with a possibility that the ram broke with the motherboard.

Thanks Phillpower2 for chipping in.
Keyboard lights dont flash.
Not a good sign I'm afraid. The keyboard/mouse are usually early on a plug and play system in the "detect list" of the BIOS. Until you can test with a system speaker installed, try the following.
if the keyboard is USB? test in another port.
test the keyboard on another computer.
Try booting with a PS/2 keyboard attached.
Your welcome Kermakakku.
Glad you got it sorted Any other problems, "Just Whistle"
