System does not start

Recommended Posts


I have an ASUS HERO VII motherboard with with and Intel 4790K 4.0ghz, and a 1080TI  graphipcs card.

Yesterday, I started the PC and I got the fan speeding up then slowed down, the speed up again, and it slowed down. It stay llike that.

Nothing was displayed on the three monitors. I had a digital display on the board that shows code 00, which could be many things.

One thing that I noticed the previous day, was that the PC clock time was off. I did check the CMOS battery and it showed 2.8V, so I went and bought a new battery, but nothing happened.

I took the 1080 TI and used one monitor with the onboard HDMI connection. Same thing.

I unplugged the Power supply (A corsair 1000) and tried a different one and the same result.

I took three of the *GB Memory sticks and tried one on different sockets and same thing. I use a different memory stick, same thing.

So for now I know it is not the Power supply, Graphics card, Memory or CMOS Battery.

I guess I am down to the Motherboard or the CPU. I don't know what to do next.

I have Build a Homecockpit B737=800, and I have two other PC's connected to my setup.

I only fly the B737 from Prosim737.

In the Main Server I have Prepar3DV4.5 and the Main Prosim menu and MCP, plus all add on scenery files. 

I am still using Windows 7 in my setup.

In the case that I have to replace the motherboard and/or the CPU, I will probably go for the latest ones.

Would the new system recognized my three windows 7 based SSD's?

Any suggestions are greatly appreciated, As I am kind of lost on what to do next.

Did you reset the CMOS with the reset jumper (or switch, if that mobo is so-equipped)? 

If the battery was low enough to corrupt the settings, you need to reflash it from the BIOS EEPROM by using that reset jumper.  Just replacing the battery may leave it in a corrupt state.
