Solved Why have my monitors stopped displaying?

December 29, 2016 at 10:06:57
Specs: Windows 10, AMD/ 16GB
So.. I recently bought a new processor. I went to install it, but have realised that the motherboard does not support it (I am stupid, I know). I reinserted my old processor, reconnected everything and replaced my fan. I tried to reboot, but neither of my monitors are displaying. I've tried checking connections and swapping out gpu's. I've tried multiple boots.

I can only assume at this point I have damaged my old cpu. I'm looking to swap out my motherboard so i can install my new cpu, but i want to be sure this will fix my problem. Any help would be greatly appreciated.

Did you actually remove the processor from the motherboard?

Not saying you did this, but folks that couldn't get the heat sink off the processor have pulled the processor out of the ZIF socket without releasing the lever. Then reversed the process the same way.

Some other possible causes are that you disturbed some wiring or cards. Solution is to re-seat all cards and cables, one by one. This includes the memory modules. In the case of the memory modules snap each one in and out 4 or 5 times to burnish the contacts.

The CPU fan MUST be connected to the header marked CPU fan.

If you didn't take proper precautions to prevent static discharge you may have damaged sensitive components.

Did you use a vacuum cleaner inside the case?

As far as swapping out your motherboard is concerned we would need to know the full brand and model number to verify the remaining hardware will work. RAM might be an issue.

Did you clean off all old paste or pad and apply new paste when changing out the processor?

What makes you think the computer is even running?

Thanks for the swift reply. I didn't insert the new processor; it's incompatible.

And you're right, I don't know whether its running or not. It powers on, but nothing happens.

Sorry if I was unclear.

Do you know which socket your current processor is?

Did you completely reinstall the processor correctly. There is a flat head screw that clicks when it is all the way in.

I don't need to be right, but I am never wrong.

Thanks for your response.

It's an am3+ socket.

If all you did was attempt to swap the processor, why would you think there's a problem with the GPU? OtheHill asked an important question which I think you misunderstood, so I will re-ask a little differently. Did you clean the thermal material from top of the old processor & bottom of the heatsink & then after re-inserting the old processor back in the socket, did you apply a fresh dab of thermal paste before reattaching the heatsink/fan? If not, that is the reason your system isn't working properly. Thermal paste MUST be used & it MUST be applied correctly. Old paste should NOT be reused.

You didn't state which CPU have have, but I see you put "AMD" in the specs. All modern AMD processors use the "middle dot" method for thermal paste application. Simply place a small dot in the middle of the CPU, set the heatsink on top of it & lock it in place. Do NOT spread the paste...it will spread on its own when the heatsink is installed. Here's a few pics:

Hi riider. Thanks for the informative post. I did not add new paste, nor remove the old. So doing this should fix my problem?

Well I followed a guide, cleaned the old paste away and applied new as instructed.

Still have the same issue. :c

Thanks for following up Othehill.

No, i did release the lever when removing my cpu, and reinserted the cup fan. I did not vacuum inside, I have compressed air

At this point i am more interested in making sure my new motherboard will work. It is an MSI main board h110 m gaming lga 1151 max 32 gb/2x ddr. Model no. 007994-013R. I'll be using 16 gb ram, i7-6970 and an amd rx 480

Make sure you bench-test the hardware before installing it in the case.

I am really confused now. The model you posted in #11 above is an Intel based motherboard. I thought you posted that you bought an AM3 replacement CPU.

The Intel board uses DDR4 memory, which you currently do not have.

Sorry the original cpu was an amd, not the replacement. Replacement is an i7.

Then you will also need to buy the appropriate RAM. Riider can give you suggestions on that.

In the mean time I suggest you try my suggestions in #9 above. That way you will at least know if you have a working setup for backup or whatever.

You probably didn't fry the CPU and unless you have a Static Discharge, you probably didn't damage the board. Just re-seat all cables and RAM as suggested.

Thank you!

I did everything you suggested but to no avail. I reasoned that maybe one of my sticks of ram was faulty, so I took one out and it booted just fine. Might play around with them later but I want to see how well my pc is running just now

I'm totally confused. AMD & Intel cannot be swapped. I thought you were asking about an AMD AM3/AM3+ processor, now you're asking about an i7? Are you saying you've abandoned trying to get the AMD setup to work?

If you swap the motherboard, Windows will no longer boot. Hopefully you're aware of that. Windows 10 is tied directly to the motherboard, so once the board is changed, that's it...Windows will have to be reinstalled.

The i7-6970 is a notebook processor & does NOT use LGA1151. Please double check your model numbers. I don't want to waste my time explaining if none of your hardware is compatible.

Sorry for the mix up. Its a 6700k.

But yeah got my old system to start up, but it made a really worrying high pitched noise after a few minutes so I shut it off again. Sounded like it was coming from the gpu. I'm going to try reseat it.

So i reseated my gpu and it seems okay. Think the sound is coming from my processor. The whining is loud and continuous, pc crashed after a couple of minutes.

I won't be working on it again tonight, but I want you all to know I'm grateful for your ongoing support.

CPUs & GPUs don't make noise. Fans make noise.
