Have I damaged my CPU?

I put together my first computer yesterday and I'm concerned that I damaged my processor while putting it into the socket. My motherboards' (P8P67 PRO)socket latch required quite a bit of force to secure in place, and I'm worried that some of the pins or the socket itself might have been damaged. On startup, the CPU fans will start spinning, then stop. They "stall" for a few seconds before starting up again. Is this indicative of a problem?

Is there a way for me to run a diagnostic or something to make sure my CPU is operating at full potential? Thank you!

No - there is no diagnostics to verify the CPU in this case (Cannot boot).
There are many other problems that may result in not booting. Please read this.

As to the possibility of damage to the CPU, you would need to remove and check the back of the CPU and the socket on the MB for damage.

The system does start. It runs POST the gives this message:

"Reboot and Select proper Boot device or Insert Boot Media in Selected in selected Boot device and press a key.:

Is there a way to check for CPU damage in the BIOS? Or should I go ahead and install the OS?

If your CPU were damaged, you wouldn't be getting this message.(or anything for that matter) :D 
I'd either boot to something like Ultimate boot CD, and run something like MEMTEST for a few hours, or go ahead and try to install your OS. :bounce:

It's very unlikely that whatever fan issue problems you might be having are related to your CPU. If your CPU were damaged, you'd be getting nothing but motherboard beeps

Simply run some CPU benchmarks and compare them online to your same model, i.e Intel Burn Test, Si Sandra, or even the small little Fritz Chess engine mark

You will need to pull the CPU out to check it. The warning you are getting means it doesn't see an operating system or boot disk in the CD/DVD drive - to install an operating system. If you are trying to use a hard disk that already has an operating system installed from a different system/motherboard it will not work. You will need to do a fresh install for your new system. Even though your system boots thru bios and might possibly load an operating system, if you damaged your cpu/motherboard pins you might get random failures, shutdowns, memory problems, video performance issues and, of course, sometimes no-boot failures. One or two bent pins will usually cause some problems where as major damage and multiple areas of damaged pins will cause more.

Best course of action??? Pull the CPU and check the pins on it and the motherboard. If no damage then clean and reapply thermal paste and reinstall carefully.

try booting from your win 7 installation disk. If that works I dought you have a damaged CPU.

Before installing operating system, I would run memtest86 from a bootable CD for at least 4 hours. You will need to download the ISO of memtest and Pur it on to a cd. NOTE you can not just copy this file, you must use the "create ISO cd" function.

If you pass memtest 86 then you are good to go - install the operating system and enjoy.

Do not pull the CPU unless you have to.

Thank you all for the replies. Is "ISO image for creating bootable CD (Windows - zip)" from memtest86.com the correct download? Will this test my CPU or only RAM?

It has to use your CPU to test the ram... :bounce:

If you download the zip of memtest86 then unzip and put on cd using the create iso. Alternative is to down load the Ultimate boot disk. It has memtest Plus other utilities.
http://ultimate-boot-cd.software.en.softonic.com/downlo...

Use memtest86 to test your memory BEFORE installing your operating system. Once you have windows 7 install and working. download CPUID HWMonitor and Prime 95.
HWMonitor - usted to monitor voltages and temperatures.
Prime 95 has three modes that you can run. default mode is BLEND test which will test both your memory and CPU.

I also had a similar issue, first time builder and so was inexperienced and didn't really know what to expect. Upon installing the CPU I did what I thought was right, lined up the CPU with the Socket on the board dropped it in using no force, and closed the cover. While I am aware this is a 'zero force' procedure a degree of force is required to secure the processor. I proceeded to apply pressure (only through pulling the lever down) and locked the cage in place. What I am concerned about is the fact that it didn't sound to healthy and I did have to apply a fair amount of pressure. I am yet to install the HDD or Optical drive but the PC once all connections are in place does not boot to BIOS, unstead it appears that I get an initial start up beep, all the fans start up, but then I get a long beep followed by 5 short ones.... any help ?

If you're not getting anything else then yes, you need to pull it to see if it has bent any pins. You might not have aligned it properly or turned it 180* off so it's not making contact with the pins. These are very delicate so be extremely careful when removing and installing the cpu.
