I've just moved house, moved my PC box myself to supposedly take care of it. I turned it on today and all appeared well and good. I got a greenscreen error after 5mins or so. Restarted it, turned on fine but this time my USB mouse and keyboard didn't work after 5 or so mins

I'm a long way from a PC store so taking it in is a drama.

I have a B450 Pro Wifi Board, the WIFI antenna ports are bent downwards and I forgot to unplug these so I thinking perhaps I've stuffed my motherboard?

otherwise, I'm wondering what the issue could be. If the motherboard was stuffed would this represent no output, I have AMD 3600X CPU so no inbuilt graphics.

If there a way of isolating this issue from home? I don't want to buy a new board if it's not that.

If I was to replace the motherboard, what's a good equivalent?? ideally from PB tech in CHCH

Just one more thing, I opened my case. My RTX2060 has two fans only one spinning so could be a stuffed GPU.

Not sure how I can test or isolate that issue?

Strip out all unnecessary components etc, just the bare minimum and see what happens. If all good, then slowly start adding components back in one at a time... if error occurs again, bingo, you've found the cuplrit.

Not good with only single fan on GPU going though.... altho if you're not loading the video card with anything, it should be fine.

Quite normal for graphics cards to have only one fan when not loaded up or hot....

The reading I've done online suggest this as well. I can't really uninstall much. I could remove RAM, GPU and see if I get to BIOS menu or at least a beep

Currently I get power so it's not that. I can't get to BIOS and I have physical damage to motherboard which is why I'm thinking it's that.

I'd try plugging a different keyboard into a different USB socket and try to get into the BIOS. If you can't do that it's not good news. I have a spare cheap Logitech keyboard I use for testing, plus a cheap tiny ebay wireless keyboard I use for occasional SSH sessions into Raspberry Pi devices.

I'm not getting to BIOS menu so removing mouse and keyboard won't do anything.

Given I can't get to BIOS I assume it's the motherboard

The BIOS is usually accessed by pushing a specific button on bootup, like Del or F6. If your keyboard isn't working you won't have access. Otherwise I'm not sure what you mean.

I guess thats the relevant new info .

Otherwise you need to part swap RAM , vid card , power supply etc to test.
Unplug ALL cables expect power , use a screwdiver across pins to start it
Pull out mb and try it out of the case
Its almost never a CPU issue .

So I've plugged in a new motherboard and it's not working.

Taken GPU out and installed an old one
Had np GPU at all.
checked monitors working via laptop
LED and fans spin so I have power
No beep, no BIOS screen

What could be the fault?

I'm still at a complete loss with this.

Could the CPU have been installed incorrectly? I thought they could only fit in the correct way no other way would work but maybe I'm wrong there.

I've literally taken everything out. No matter what I do the thing will not boot to BIOS.

Have you done a visual on the CPU pins to make sure everything at least looks good (no malformed or missing pins)?
