Is it the Mobo?

[rodel100]

Alright, I couple months ago. My computer started giving problems.
I read quite a bit of threads here and there, summed it up to the PSU.
So I replace the PSU with one that works for sure(Used on another computer). And now the computer won't boot. Even if I switch the psu back to the old one.

Here are the symptoms:
Fans would power, Green led(on sign) would light up(Not after the PSU change). Would hear the beep for power on, but nothing will happen/no post
Green light for SD card eternally on.
No sounds after beep.
GPU fan does not spin (probably not being powered)

And before it'd take about 2-3 hours for my computer to boot up( I mean It'd take 2-3 hours for it to hit post let alone windows start up)
Then when I was inside and everything. If I clicked a program anywhere, the program would freeze(Not responding) then respond again then freeze then respond again. And so on and so forth.

Can someone till me the issue, I've had this computer for 5-ish years though.

Do you have the 20+4 and the 4/8 power cables connected to the mobo? snugly?

Yes, I have them pushed in nice in tight. I just checked, and everything seems connected well and snugly.

Try taking the cmos battery oout, unplug the computer, take it out, leave it 10mins put it back in and powerup

Say what happens. from the moment you press the button

Nothing, nothing happens. Same result as before.

So:

Powers up fans
No Picture
And Beeps once, then nothing?
