(with the system turned off and power plug out) remove the cmos battery wait a bit then replace the battery plug the power back in and boot. see if that fixes your trouble.

I did what you told me but it does not work. It was able to bootup in window but for about 3 min i would have a distored color screen then the blue screen came one with all errors message.
Now when i boot up i hear the one beep then 3 quick beeps after that and the bootup in window.
I 'm searching for the beep code on this ASUS m4a785td-m evo to see what is the errors message is about!!

no, i have not!!.
It workong fine for about 7 months after i build it then i t got unstable, reboot frequently. I thought that was software problem so i wipe all software out, reinstall window and slowly ad back the software one by one and it work for about 5 months till now.
I have 2 stick of crossair left , i'll dry that.
One awhile it would gave me a long countinue beep untill i shut it down and that got me all confussed
Thanks for helping
