No signal? Help?

[Sovnsauce]

Hi,

I got home today, turned on my computer, everything fine and dandy, until it crashed whilst logging on, so i had to turn it off and turn it on, except i couldnt get back on because i keep getting "No signal" any help with this?

Things i have done:
Took out every individual component and tried to start it up without said components, no luck with that.

Cleared CMOS

Unplugged all wires and replugged them back in.

And yet it still wont work, no sound coming from POST...

Also, my perepheral's lights come on (Blue mouse, red headset etc) however when i start my computer, my keyboards lights dont come on (like they should), just thought that might be useful.

thanks.

When you turn on the computer, are all the fans running? Also, try plugging the keyboard into the mouse's USB port and the mouse into the keyboard's USB port. If you do that, do the mouse lights fail to come on, and the keyboard ones come on?

All of the fans are running, my GPU has a MSI light on it what also turns on, the corsair light on the cooler also turns on, i switch the USB ports around and the mouse light comes on fine but the keyboard one doesnt come on.

Could you plug the keyboard into another computer (or into any electrical port) to verify if the lights come on?

 

[Sovnsauce]

Just plugged it into my laptop, they turn on, however the lights on the keyboard never turn on until after the computer has gone past POST and has gone past the initial BIOS screen.

Well, the culprit is going to be either the power supply or the motherboard. Power supplies can cause freezes like that. You do have a high quality power supply, but undoubtedly it does endure a lot of load with your system, but it can handle it. At this point, it's just going to be the swapping game. I think the motherboard is more likely broken. The PSU successfully turns on the build now, so I think for sure the motherboard is the problem.

Ill try and get a new board, if it still doesnt work then i guess ill get a new PSU, i need a new board anyway as i cant really overclock on it so i have a bottleneck, and i need a new PSU as whilst it is of good quality, 550w is running the line a little bit lol.

Thanks for your help

I don't think the 550W PSU should be an issue. You have a very high quality power supply, and power supplies are designed to run up to their specified wattage.

Just a quick update, i just got back, turned on my computer, and it just worked, absolutely no idea what was wrong with it, no errors or anything, it just works as before.

Still, i will keep an eye on it, i need a new motherboard anyway, but i was hoping to wait until AM4 boards come out to replace it.
