Is my CPU fried?

[arcooke]

I was putting together a computer out of some spare parts today, and when I finally finished hooking everything together, I turned it on, and nothing.  All the fans start spinning, but that's it.  No beeps, no video, CPU (AMD XP 1700+) doesn't get warm after 10-15 minutes, hard drive doesn't spin up, nothing.  The light underneath the HD lights up as it should, video card fan spins, etc.

I tried running it barebones.. just mobo, cpu/heatsink/fan, ram, keyboard.. still no beeps.

As a last resort, I thought hey.. maybe I need to reseat the CPU.  When I pulled it up, there were 10 little very light brown (or off-white) markings on the thermal paste.  Those markings were from the 10 little chips on the CPU as pictured below (not sure what they are called):



And this is sort of what the thermal paste looked like (notice the darker markings):



I don't know what would have caused it to fry.. that's why I'm a little confused.  The cpu/mobo were working just fine for a long time.   About 6 months ago, I ordered new parts and stored the old ones away in the closet (still connected).  All I did today was reconnected them to a different case.  All of the parts I used today are the same as were in use together 6 months ago.

Is there anything else that would cause the computer do this?

Any ideas? 
Thanks

What kinda beeps are you getting ?

sounds to me like your mobo has gone
because if the cpu had gone it would not even power up

Firstly, try swapping the PSU with a known working one to rule out the PSU.

Does the system reset after a while or does it just hang, doing nothing?

To answer both of your questions:

@simshi003052
- Like I said above, I'm getting no beeps whatsoever.

@GX44
- I have already tested 2 PSUs, same deal.
- The system does not reset.  I left it on 10-15 mins to see if the CPU would warm up and it did nothing at all other than run the fans.   As a matter of fact, the reset button didn't even work when I pushed it.. but that could be a problem with the case.. it's old, and was given to me.


Another note, I have also tried other memory.

Are you getting a screen at all .............. im not talking about messages ........ are you getting any boot of the sort......... this may be 2 things your mobo and your cpu........


Something has almost 100% messed up

(are there any beeps) sorry did not read the message properly
been up all night

if you have trie dtwo other cpu's and it still does not boot up then it is definetly your mobo
you should be able to pick a used board up for a 10 bob note
from your local dealer

Pull those components from the case...hook up only the CPU and fan; PSU; vid card; 1 stick of RAM; monitor mouse and keyboard....see if you get any beeps.
If not re-seat the CPU and heatsink and try again.

Keep us posted.
