Asus Motherboard M5A99X EVO won't boot. No signal on monitor

by KR0G / June 20, 2012 5:04 AM PDT

I just finished building my pc and everything works; power switch, fans, LEDs, you name it. I connected the monitor to the graphics card using HDMI to DVI respectively, and I get no signal on the monitor. The CPU LED is also constantly on red. I'm 100% certain the CPU is put in right. It is an AMD Phenom II X4 3.4ghz. Is the BIOS on the motherboard compatible with the cpu? Do I need a new motherboard? The motherboard and cpu are both socket AM3+.

I'm also using an SSD, which I know is working because of the LED inside.

I tried it on a different monitor as well, using DVI to DVI.

No SSD needed for video display.

I can't tell but it sounds like you put it all together rather than using the bare minimum parts to get a beep or a display.

Start smaller. If no display, remove parts to get just a beep. LED's mean nothing. You learn this after a few rounds.

I have the motherboard, processors, power supply, memory, ssd, optical drive, and graphics card installed in the case. What should I remove?

But I guess it was unclear. We start as small as possible. All I need is 4 parts to get a beep. PSU, CPU+HSF and the Speaker. No beeps and I'm looking at the bad or badly configured parts.

And what does the beep signify?

That the CPU ran a little code from the BIOS.

It's a shame you didn't reveal the test result. If we move this slowly I may have to write to take it to a shop. Love to help you along, but let's move a little faster.
