So here's the problem: I was using my computer tuesday, and turned it off in the evening, after which I remembered I still had to print my ticket for a NYE event, I try to start my pc back up, nothing happens. As if there's no power going to it. Having no time to fix it I left, and decided to look at it the next day. So wednesday I try to start the PC, and it boots everytime; fans are spinning, 1 post beep, keyboard and mouse light up etc etc, except that my monitors are giving me the no signal error everytime.I tried a couple of things: Holding the power button for up to a minute while the power cord was out, reseating the RAM, testing out with 1 stick of ram at a time, taking out my gpu, and taking out the CMOS battery for a couple of hours. As of now sometimes the PC boots and gives me the no signal error, and whenever I change something in my setup it doesn't do anything at all. What could have happened in that short time frame that it was off (~10 minutes) on tuesday, and how can I fix this. I used psu/video/etc failure flowcharts which led me to the CMOS battery needing to be cleared, which I did, after which point my PC, sometimes doesnt boot at all anymore.
Specs: CPU:i5-4570k MOBO:Asus B-85PLUS RAM: Corsair something 16GB dual channel ram 1333hz GPU:palit GTX 780 PSU:Corsair CX750 bronze certified Sandisk SSD Seagate barracuda HDD Coolermaster HAF x case System is a couple of months old. W7 Ultimate 64bit
Thanks for any help you can give me!

@snyte, just a single post beep /if/ the system powers up that is.
@t21 I already tried with using 1 stick of ram(both of em). I'll disconnect the HDD and the gpu now to see what happens.
I should mention I have already had the mobo checked out when I built the system due to having problems with it, ended up RMA'ing.a working mobo and they sent it back to me.(ended up being a faulty stick of ram,which I then RMA'd)

If you are still troubleshooting your memory sticks, try using Memtest86+ http://www.memtest.org/ (I've seen a few posts here and there about the tool and everyone seems to be happy with it, meaning it's a good tool to test your memory).

@t21 Yeah I did that, I may have just worded it a little strsnge earlier. I'm still getting the no signal message.
@warsam Memtest is great....when your system actually boots up that is.

Sorry Zanzonyx, I didn't realize your system wasn't booting. My apologies...I just saw t21's comment about rma-ing your mobo. Hopefully the new mobo will do the trick.
