So today i turned it off and when i came back to turn it on it turned on just fine...but the screen said "no signal" and there wasnt a boot beep like normal. I use an Emachines monitor and it was working perfectly (i know its not my monitor because im on my emachines pc right now using it and i used it right before i turned off the pc)
I reset the Bios and even checked the ram one by one and even removed it.
my motherboard isnt beeping when there isnt ram in it either.
All the Fans are running and i even reseated the CPU.
Also the Power button turns it on but wont turn it off and im forced to unplug it.
So if anyone can help it would be GREATLY appreciated. Thanks!

I haven't heard a beep code in 5 or 6 years .... haven't done a build that has a speaker in that long.
Have you used the on screen menu to insure that the correct input source is selected ? Are you perhaps using DVI on the e-machines and HDMI on the other one ? That would generally require reselecting the input via the OSM.
odd that the 220v lets me turn off my pc but the normal setting is 115 Im not sure whats wrong but this allowed me to turn off my pc Any other ideas?
I have the exact same problem and i can't beleive that the mobo can be burned. It should be a simple thing but the point is what could it be?. I'm sure that the MoBo is working but for one reason the video don't want to come up. Who can explain that in mine the video card get hot?. The truth is that one thing i read here is the voltage could be also by a mistake in 220 V - 50 Hz, it is a simple switch, that was something that i didn't check but anyway i tried with two PSUs
If you have a dedicated videocard, remove it. Remove the RAM as well and check to see if you have memory error beep codes.
If still no beep codes, remove the hard drive and ROM drive. If still no beep codes with nothing but the processor in, you have a bad motherboard.
Ok, I done all this, and the only thing left is the CPU and the CPU-fan.
I also tried the CPU in another motherboard aswell.
The AMD CPU is an AM3 SEMPRON 140 and I have unlocked one of the cores so its has total of two. I Overclocked it to 228FSB and it run fine for 5 seconds then the computer died. Have a killed the CPU now ?
I Believe switching the rams and trying different slots might solve the problem. It has worked for me couple of times when I get the short circuit like power ,that is: fan going on and off and everything seems to be working for couple of seconds, its either a Power Problem or Ram related problem.The best way to detect it is run by the list and start from the power supply and work your way down to the motherboard.I Hope that Helps.
There is also the basic solution of holding the power button down for 30 and plugging the power cord back in.
