I've had my PC for about 10 years and as of today when i boot it up, i get 'No Signal' on the monitor and it just stays like that. This PC does not have it's own dedicated video card so i just use the on board ports.

Motherboard - Gigabyte GA-A75-UD4
CPU - AMD A4-3400 APU
RAM - 2 x CRUCIAL 2GB PC3-10600 DDR3-1333

Things i have tried -

• Using different cables (VGA and HDMI)
• Using different monitors (VGA and HDMI)
• Cleaning the RAM (this was a suggestion i found online)
• Installing different RAM sticks
• Installing a dedicated video card that i know works
• Installing a different power supply that i know works

After all of the above failed to get me a signal. I suspect the motherboard has failed however, all fans plugged into it seem to be working. I also plugged a USB stick into the back of it (one with a light on it) and it lit up fine, which means that it could be working. So could this be a motherboard issue? Could it have something to do with the CPU?

Thanks.

If a standalone video card is not working, there is likely a hardware fault of some sort. Also, I will point out that the system is likely not completing POST. In other words, it's not getting to the point where it would even output a video signal.

I would start with the sticky: How to Bench Test, Build, and Troubleshoot Your Computer

I managed to get hold of another motherboard and it worked fine. Old motherboard must have failed. Thanks for the help.
