Please help guys. My pc in the sig below has been running flawlessly for ages now. Was on yesterday and all was good, shut it down.

Today, tried turning it on and there are no beeps and no display. The mb lights up and you can hear it clicking trying to do something but that's it.

What should I check please?
 
I've managed to get it to boot now. Once booted I realised that my leds lights that are plugged into the mb have stopped working.

Strange. I tested them by plugging into a different fan socket. They worked! So the lights are fine, seams the socket has failed. I plugged a fan into the socket and that didn't spin either.

I thought I'd do a benchmark in 3dmark but every test fails. They never failed before. I removed the gpu overclock. Still failed. Weird. The test seams to fail when it does the physics and crashes out.

I noticed in the system info that it said my Intel graphics was on, strange, it never used to be.

I went into the bios and turned it back off. I then realised that my cpu overclock has gone! I can't adjust the settings no more either. It does nothing when I select the ratio etc.

What the hell has happened? Any ideas?
 
Ok it's stopped crashing once I shut down afterburner and rivatuner.

But where are my overclock settings gone etc? Do you think it could have changed the bios as it's dual bios?

What's the power consumption of those lights?
They might have burned that fan output.

And some kind hardware crash could have certainly made motherboard switch to back-up BIOS.

Not too sure without checking. They have been on there for over a year. I have 2 darkside uv strips on a splitter connected to one fan port.

It is now unplugged till I find out what happened.

I've just upgraded my bios and setting it up again. I've got my overclock back.

Will keep an eye on it over the next few days.

Thanks mate :)
 
It's not safe to assume motherboard fan header being capable to more than 1A so two light strips might be too much.
 
Guys it's done it again. Didn't boot and just ticks every few seconds. No beeps. Tried to restart it and got this image...

Do you think my motherboard has had it?

Also just to add I've removed all the old lights so there is nothing connected to the mb fan ports. I've added the corsair lighting kit which runs from the psu.

I've also updated the bios to the latest version.

This fixed it for 3 to 4 weeks but has started again now.
 
Why would you plug leds in to a fan header?

I have seen problems with that motherboard before with it powering up with the BIOS de-configured or corrupted. I seem to remember it frequently reset various settings without any real logic. As to the cause it seemed to be power related. Now that could still mean a host of things, it could be the PSU or it could be something on the motherboard itself that glitches sometimes when there is that first initial inrush of power. I would actually try a different PSU just in case it is, I mean it's easier than replacing the motherboard, CPU and RAM :/ But be prepared for it not to make any difference.
 
The leds were designed to be plugged into a fan header.

Funny you should say that as my cpu overclock settings were gone and reset to default. So I just assumed that because of the fault it switched to the secondary bios. I then upgraded to the latest version. Reset my overclock and was good for a few weeks.

When I first got this pc I had to rma the motherboard because of it not starting after I installed a new power supply. This was when it was a prebuilt and nearly everything has been changed now apart from the CPU, mb and ram.

Surely I should just get a second hand mb instead of upgrading the lot?

Not got a spare power supply to test really. I put my money on the mb because of the old issue it had. I just don't trust it.

I'd just like some other people's opinions before I replace anything.

Thanks. :)
 
From what I've read for gaming there isn't much point of upgrading the cpu, ram and motherboard. Is that correct? If so should I spend £150 on a secondhand board to keep what I have? I'm not sure.
 
Ok I'm getting the itch now for a i7 8700k and an asus rig strix z370-e gaming mb with 16gb of 3000mhz ram. What's your thoughts on this guys?
