[SOLVED] PC stopped booting properly after swapping GPU ?

[BigBird21]

Ok so basically, yesterday I started to smell something burning coming from my pc so I opened it up to see what was burning. I'm pretty sure it was my gpu so I took out my gpu (GTX 1070 TI) and put in my old gpu (GTX 970) to make sure that it was the gpu that was making the smell.

So I plugged everything back in like normal and went to boot my pc and everything inside the pc itself was working fine, like all the fans were spinning etc. but nothing happened. None of the monitors turned on, the keyboard and mouse didn't turn on etc. I tried to plug my monitors into the motherboard and gpu to see if either worked but nothing happened. I made sure that everything was plugged in properly but still have no luck.

I have had the PC for 4-5 years and haven't had any problems with it apart from my SSD corrupting or a windows file corrupting on the SSD. So I replaced the SSD 1-2 years ago. Other than that it has worked completely fine for 4-5 years.

My specs:

GPU that I normally use: NVIDIA GeForce GTX 1070 TI zotac edition

Old GPU that I still have: MSI GeForce GTX 970

CPU: i5-6600k

MOBO: MSI krait gaming Z170A

PSU: Corsair CX750M

RAM: G-skill ripjaws DDR4 16gb (2 8gb sticks)

OS: Windows 10

Any help is greatly appreciated. Let me know if you need any more information.

Thanks in advance.

modular psu? check the cable connection on both end?

A motherboard will switch to a discrete gpu if one is present.
To test with integrated graphics, remove the discrete graphics card.

To test a discrete graphics card, boot in safe mode(f8).
That will load windows with only safe and minimal graphics drivers.

If no joy with any graphics, you have to consider a motherboard failure.

It might be time to consider an upgrade instead of a motherboard replacement.

$250 can buy you a stronger i5-10100, a lga1200 motherboard and 16gb of ddr4 ram.

Other good options abound.

All the connections are in properly.

I tried your suggestion with both GPUs and integrated graphics trying to boot in safe mode. Had no luck with any of them. I was considering upgrading a few weeks ago anyway so I have some other components in mind. Is there any other suggestions that I could try to use to fix the issue?
