Hello, I've recently come into trouble with my computer. I built it myself a year ago, and when I moved last month it no longer works. It powers on, but the monitor says 'no signal'. I tested all the HDMI ports on the monitor, swapped HDMI cords around, but they all check out using my PS3. I decided it was all right for me to go ahead and replace a few parts.

I went ahead and got a new motherboard and graphics card, but no change. The new motherboard has LEDs to show if specific parts are responding, and the CPU's LED was red. I went ahead and picked up a new one too. STILL no change. I've been spending half a month researching various forums for this problem and so far I haven't found a fix. Any and all suggestions would be GREATLY appreciated.

Are you saying that with the new CPU installed, you still have a red light for the CPU?, (to the left of the CPU socket, 3 vertical LEDS)
This does not indicate that the CPU is bad. This indicates that the CPU is in Crazy Mode, meaning the voltage is at 1.5v.

If you have a red LED, (bottom one of four, to the right of the 24 pin power socket) this would indicate a CPU problem.
Please go link and download the updated user manual as it may be different from an older one that came with your Motherboard. The board is very sophisticated, so you must carefully read the manual to find out what the LEDS mean. > http://www.asus.com/...rmula/#download

Have you connect 2 power cable to the Motherboard. The 24ATXPWR and the (your PSU has 1 x 4+4-Pin ATX/EPS 12V0) as well as the CPU fan plug? Look in your manual, Motherboard Installation.

To clarify, it's not the CPU - crazy LED, but the one near the 24 pin socket. I have indeed plugged those in, and looked at the manual. Going to flip through it again now, but I've read through it about five times already. At this point I'm certain I'm overlooking something due to stressing over this mess!

Has it been suggested that you do a bare bones system test outside of the case.?
