Hello, yesterday i accidentaly knocked over a glass of water on my case, i immediatly shut down Windows. Since it took so long, i switch it of via PSU switch without a proper shutdown.
Took out all parts, tried to locate the damage but there was no water,anyway i put them back together and gave it a go. First, no posting,no beep but it had power, fans were working except CPU fan. Then a couple of minutes later CPU fan worked too. But it still got no post, no beep or display. Also holding down power button wont shut it down.

I tried Rams one by one,tried CMOS reset, took out bios battery, controlled all cables in case any damage. I believe i fried my MB because of water. Whats your opinion on this and what should i do next?

Test with the minimal configuration for your build; it would be easier to help if you provided details about your system. You could replace the motherboard, but it may not be the cause of your issues or there may be several defective parts, particularly if you didn't wait for 24-48 hours for the parts to dry completely. If testing a minimal configuration with a known good PSU doesn't work, then have a have a shop or a friend (he/she needs to understand the risks) test the CPU and memory modules; if they test fine, then the motherboard probably went bad.
