Is my CPU dead?

Ok, so I'e been having some problems with my pc, It was powering up for less then a second but would then switch off. Thinking it was my PSU I've replaced it but I'm still having the same problem.

I've found that one of my hard drives is causing something to short as when it's not pluged in everything lights up properly, except for the CPU. The mobo status LEDs are all red which means there's a processor malfuntion of some sort. I get the same result regardless of the whether the 12v auxhillary lead is in or not.

To touch the CPU is stone cold, another indicator that it's not working however I've heard that it's extremely rare for a CPU to die but I can't think of any thing else. So, any ideas?
 
Looks like it is, When my Q9550 died same thing happened, it will turn on for about 5-9 secs and then shut off. Replaced it with my old E5200 and everything went back to normal.

Take out the chip and check if something is causing it to not contact properly, If the motherboard says its the cpu, then it is, also try just booting up with 1 ram stick to make sure.
 
I've never seen a CPU "Die". Something else has to be causing the problem... I'd troubleshoot some more... unless you get RMA-happy...
 
Take everything out of the case and hook up the bare essentials only: motherboard, PSU, CPU and cooling, 1 stick of RAM and video card. See if you still have a problem then. There might be a screw or something else causing grounding issues and this should determine whether or not the problem is a grounding issue.

 
If the heasink remains at ambient temperature after letting it run for a while, is it a good indicator that the cpu is dead? Or can malfunctioning cpu's still produce heat?
 
Well my malfunctioning CPU burnt a hole in the motherboard LOL.

To me it sounds like a motherboard issue, do you have a huge heatsink and been moving the case around? I've seen motherboards de-laminiate when flexed that could be the issue.

If you have a fry's near by they will test your CPU or board for free at the RMA counter if you ask nicely.
 
I did have a Pentium 433 go belly up on me once. RMA'd it to Intel.

It is hard to say for certain because the mobo and CPU work so closely together. From your description of the symptoms, I am kinda leaning towards the CPU also, but it could still be the mobo or possibly both. One of the voltage regulators on the mobo may have shorted taking out the CPU.

Good luck.

I'm not sure, my cpu isn't warming up at all, I can run it without the heatsink fitted and it don't heat up, (I only did this for about two seconds).
