Computer wont power up

[Nnooooo]

Old psu blew out so I replaced it but now nothing comes on. I've tried another psu, both 550.

Power light comes on, the mouse lights up, but no beeps, no fans, no image on the screen.

Ive changed the motherboard and the processor too. I've also swapped power sockets and power leads.

I've even changed the case...

Do I need a priest?

"Do I need a priest?" maybe (sorry, just too opportune).
Have you tried to boot into Safe Mode?

• boot & strike F8 once / second
• in B/W vga screen, select Safe mode
• in colored screen, select Admin and give the password
• and you land on the Admin desktop

So, how far do you get?

Not even that far. No image on the screen. Not a sound from the motherboard. It's like it's not plugged in, except there's power getting to the power light on the front and to the usb mouse.

Assemble the motherboard outside the case with just one stick of memory, CPU and video card if no on-board video is available. See if the computer posts

Do you mean boot?

I'll give it a go but it's gone from one case to another already.

No, see if it just begins to boot like showing anything on the monitor. If still nothing, you have a bad part somewhere...

Do what Tmagic650 said, if that doesnt work, your motherboard's probably fried.

Also, try just removing the ram and try booting, then plug one ram stick , try different slots and see if it makes any difference

The motherboard should start beeping with no memory installed. You might have to attach a speaker to the board to hear it
