Is my cpu dead?

[Crownregent]

One week ago my pc died on me. I could click power button and hear it hum for 5 secs or so and then just die down for no visible reason. Nothing smells, however once i remove the CPU from the motherboard and put the power back on the computer hums like always before.. Which leads me to belive the cpu took the night.
Im on a M2N32 SLi wifi ed.
5200 Processor AM2
3 gig ddr2 from OCZ 4 4 4 12
850 W OCZ gamestream
AMD 4850 512 vid card
2 x 320 gig ram
Vista 32 + Win 7 dual boot

Any suggestions?
(hell i even tried to reapply thermal paste to no avail... )

So is my CPU dead? and which CPU can i use as replacement? Some says Phenoms will work likea charm while others say nay... so... what is it?

Need answers asap

You do have another am2 CPU, right?

 

[Crownregent]

Not at the moment. But thinking of ordering the AM2 940 or the Phenom 9850 since both are supposed to work with the mobo.

Well you can't really single it out as your CPU. Perhaps its still under warranty?

Try these troubleshooting tips:

Pull everything except the CPU and HSF. Boot. You should hear a series of long single beeps indicating memory problems. Silence here indicates, in probable order, a bad PSU, motherboard, or CPU - or a bad installation where something is shorting and shutting down the PSU.

To eliminate the possiblility of a bad installation where something is shorting and shutting down the PSU, you will need to pull the motherboard out of the case and reassemble the components on an insulated surface. This is called "breadboarding" - from the 1920's homebrew radio days. I always breadboard a new or recycled build. It lets me test components before I go through the trouble of installing them in a case.

Example of breadboarding:

If you get the long beeps, add a stick of RAM. Boot. The beep pattern should change to one long and two or three short beeps. Silence indicates that the RAM is shorting out the PSU (very rare). Long single beeps indicates that the BIOS does not recognize the presence of the RAM.

If you get the one long and two or three short beeps, test the rest of the RAM.

If good, install the video card and any needed power cables and plug in the monitor. If the video card is good, the system should successfully POST (one short beep, usually) and you will see the boot screen and messages.

Note - an inadequate PSU will cause a failure here or any step later.
Note - you do not need drives or a keyboard to successfully POST (generally a single short beep).

If you successfully POST, start plugging in the rest of the components, one at a time.
