Windows 10: Lost Power, now PC won't boot. Powers on and clicks.

I had tried both of those steps. Neither worked. I have a replacement power supply on order. Should be here on Monday. Thanks for the suggestions.

 

Please confirm you have done these checks:

• Confirm PSU turn on works - Google "PSU paperclip test"
• Remove the GPU card and use the internal GPU - I've just had a PC fail to boot due to a bust GPU
• Remove the BIOS battery for a minute, install a new one and select Load BIOS Defaults

You could also try booting from KYHI's repair disk on the forum and use this to check your disk health.

 

Hope for sure it is the Power Supply without testing it and the checking the Graphics Card.

 

Can you get into the BIOS/UEFI screen?

If yes:
Does it show that your all of your drives are present?
Do the motherboard voltages appear to be correct?

 

I cannot get to bios, as the machine does not post. No beeps, no output to screen. It just turns on and does this:

Clicking noise on startup. - YouTube

Unfortunately, replacing the power supply did not help, which means I have another problem.

This system does have onboard video, but even bypassing the external video card and resetting CMOS, I am still not booting. Unless I am wrong, this means I either have a dead board or maybe a dead CPU??

 

I should mention. It makes that same noise even with all drives disconnected from power and the motherboard.

 

Yea,..I'd go along with that now. You've bypassed your GPU, confirmed its not the HDDs and replaced the PSU. As you say, either CPU or MOBO. Both expensive items too so which one to replace first and hope that was the right choice?

 

Quote me if i am wrong but if the graphics card is bad you will not see the post screen at boot or thereafter.
Some BIOS will not appear either.

 

Right, but I don't hear it post like I used to. It's so weird really, and unfortunate, as this thing is barely 2 years old and was not a cheap board. Now I am torn as to which part to replace (Leaning toward MOBO), or if I should scoop some extra cash together to upgrade the entire thing. Decisions...

 

The other piece that I just thought of... Dangit.. My copy of windows 10 is tied to this machine. If I replace the motherboard, what does that mean for my copy of windows??

 

You'll have to move it to the new motherboard:

I've just replaced a bust AMD GPU which would boot to the BIOS screen but not Windows. I only suspected the GPU since I noticed some coloured vertical GPU artefacts on the BIOS screen.

 

Do your old and new PSUs pass the 'paperclip test"? See http://support.antec.com/support/sol...paperclip-test

Your new PSU could be a dud but that's unlikely.

Remove the CMOS battery for a few minutes and try removing and reseating the RAM and GPU cards. Check all power cables to the motherboard are firmly connected.

 

Even brand new motherboards can be dead-on-arrival as happened to me 18 months ago during a PC build.

Truth is,..when diagnosing a faulty PC, you really need to have lots of spare parts, virtually another PC if one is to have any hope of trying to sort out a problem should it be a physical one which in this case, it sounds like it is. Not a practical solution for many I know but even purchasing cheaper spare parts over a period of time would come in handy for that fateful day.

 

Yeah. This is my only Intel machine so no way for me to simply replace parts at this point one at a time. It's a socket 1150, so trying to replace the motherboard means making an investment in old tech. I cannot find one just like this one unfortunately, which is a shame as it was actually a pretty good one. So I am torn about what to do. I opened a case with the motherboard manufacturer last night, or at least I think I did. I believe this motherboard is still under warranty.
