Re: Did I blow my processor?




Most of the motherboard gives beep tone or light indication when POST completes. 
If there is no sign of life( no beep or even a led blink) then probably the MoBo not even attempted POST.

I suggest to double check that all motherboard power connectors are connected . 
Usually 4pin or 8pin 12v motherboard power connector(which you already connected),large 24pin motherboard power connector and sometimes additional 4 pin molex connector.

There might also be an issue with power switch. You can try disconnecting power switch and touch the power switch pins simultaneously with conductive metal like screwdriver. Just careful when doing this.

One time I hooked up the power switch to the wrong jumpers and it took me an hour to figure it out.

I would suggest double checking everything to make sure there's nothing you missed. And as Felix already mentioned, parts can be dead on arrival so that is the next thing I would look for.

I've done that many times while building, replacing or troubleshooting. You
can't hurt a CPU by not giving it any power.

I did that and it
still won't boot up, and still no messages diaplayed on the
screen or any other indication of life.

Have I ruined my processor turning the system on with out
the 12V attached? (This is the four wires from the power
supply that plug into the mobo right next to the processor,
for those that may not be familiar with installing stuff.)

What have you done to prove your power supply isn't bad? New ones can be DOA.
Did you install 100% compatible RAM? Did you try installing only one RAM stick,
or leaving all unnecessary devices (if there is onboard video, the gfxcard; HD;
DVD reader; accessory USB ports; speakers; etc.) disconnected? Are you sure the
CPU is fully compatible with the motherboard's firmware/BIOS/chipset (just
because it fits the socket is no guarantee it will work)?
