M5A78L-M Plus Mobo
GTX 960 gpu
AMD fx 8320e CPU
2x 4GB Ram
600w PSU
1tb HDD

Here is, as best as i can, a description of what occurs when i hit the power button.

Power button is pressed. Fans spin, lights from the power button turn on, and i can here the HDD power up. Monitor says "no display ENTERING POWER SAVE MODE"

Worked for 6 months after initial build without any complications. Ran any game I threw at it on max with atleast 60 fps. Now, after cleaning the dust out, I get no display. My monitor goes straight into power save mode. PC fans and drives turn on but im not sure if its booting as i do not have a speaker. I get no lights on keyboard or mouse when i let the pc run.

things I've tried include:
1. removing cmos battery for well over 30 minutes (no luck)
2. booting with 1 stick of ram as well as trying each slot individually (no luck)
3. replaced CPU (no luck)
4. replaced MOBO (no luck)
5. replaced PSU (no luck)
6. Tried monitor on a different pc (monitor works)
7. booting with nothing but keyboard and monitor plugged in (no luck)

I get no display from either the onboard or GPU regardless of the plug/input I use. having replaced everything but my ram and gpu I think it might be one of them but I want to be sure before I drop money for another failed attempt.

If anyone needs more info let me know.

Solution
When you are testing the onboard video, are you removing the nVidia card? If not, do that. Try booting with no hard drive connected. You replaced the full computer pretty much, so unless you are not hooking up something properly (say motherboard stand-offs or the power plugs to the system) there is something outside the motherboard and power supply that is the issue.

I am removing the nvidia card before testing the on-board graphics and still not getting a display. This leads me to believe its something else. I'm at work right now so when I get home I'll check the standoffs and most likely go piece by piece to see what I can figure out. But yeah I have replaced the whole PC it feels like so I was getting the feeling i was just being dumb and forgetting something. That's why I am posting here ha-ha.

I've got the Mobo out of the case on a price of cardboard with 0 stick of ram (tried with 1 and no change) cpu, CPU fan and still no display. Monitor says no signal and turns itself off. It's plugged into the onboard VGA port if that matters. I have to use a VGA to HDMI and an HDMI to DVI to plugged it into my gpu as it's an older 1400x900 monitor.

I need some suggestions on what to try because I've been tinkering with it on and off for months and nothing I've found via Google has helped. All the solutions never work. I figured a brand new mobo would at least give me a bios. That's all I ask.

P.S. By loking at the mobo box I've found out what I thought was a VGA input is actually a D-Sub. Will VGA still work in that output or do I need to run adapters to connect to the onboard dvi?
 


You should have someone else that knows about building computers check over what you did. You replaced the full system and it still does not work, which could mean you are overlooking something. D-Sub and VGA are the same thing for all practical purposes, it's mostly technical semantics difference, but they are the same port. D-Sub is really any type of connector that has that "D" shape like a VGA port. And not sure what you are doing with all those adapters if you are using the VGA connection on the motherboard. What do the converters have to do with any of the testing? You don't want anything extra when testing, meaning no video adapter. How will you know if the compute is bad or if the adapter is?
