CPU or Mobo dead

[Killswitch]

I had a similar issue with my HTPC. I swapped the cpu out, changed ram, tried different ram slots, removed sata drive connectors...... nothing. Fans would just turn a bit. That's it. But it fired up after removing all the fan and front panel connectors to the chassis (USB, power, reset, etc). I then started plugging everything back in one by one to see what caused it to not boot up, but it did every time so something just glitched. Ever since then I haven't had any issues with it.

My advice is to strip the board of all connections except the power connectors you need to let it boot up into the bios. If that works then start plugging everything back in, one at a time, shutting down each time in between, until you figure out what's causing it, or in my case somehow fixing the issue. haha

Any beep codes?

Everytime I connect it to the board, my PC doesn't turn on.
But when I unplug them, my PC turns on including all the fans, but there are no beeps or anything.

My PSU has two 4-pin connectors, and both of them are now broken.
Are there any way I can fix it? :(

Please specify, or perhaps post a picture. Which 4 pin connectors do you mean?

Can I just use an electrical tape to fix it?

And another thing, when I don't plug in the 4-pin connector, my pc opens including all the fans,
but no beeps or any display on the monitor.
Is this just because the 4-pin isn't connected? Please correct me if I'm wrong

What do you mean by "a bit open because it was shorting out"? Is it burned? If so taping it up and trying again won't solve anything until the issue is solved. All that could do is potentially cause more damage.
