Upgrading CPU! HELP

I ordered a AMD Phenom II X4 940 Black Edition Deneb 3.0GHz and it just arrived. But the problem that exists is that when I installed it, the computer responds with a black screen and a sentence "CPU NOT INSTALLED"

The problem i think that interferes with this processor is either my motherboard does it support it or my power supply is not sufficient enough to run it.

So my question is what should i do in this senario? Should i return the processor and buy another one with lower power consumption or increase my power limit overall?


-Manufacturer: Pegatron
-Motherboard Name: M2N68-LA
-HP/Compaq motherboard name: Narra5-GL6
-AM2 socket
-250W power supply

The specifications that were listed does in fact say it supports it.
Motherboard supports the following processor upgrades:

-AMD Phenom II Quad-Core
-AMD Phenom II Triple-Core
-AMD Phenom Quad-Core (A) 9xxx series (AM2+)
-AMD Phenom Triple-Core (T) 8xxx series (AM2+)
-AMD Athlon X4
-AMD Athlon X3
-AMD Athlon X2 (B) (AM2+)

  1. It may be non refundable but will they allow you to exchange it for what you can actually use?

    What are you trying to do with this system? Game, multitask, etc...

    Did you try to reinstall to make sure you seated it correctly?
  2. Yes i definitely made sure the pins weren't bend, dirtied, etc... and i have reinstalled a couple of times just to find the same situation, a black screen and "CPU NOT INSTALLED".

    And this computer is definitely for gaming.
  3. Depends on where you bought it from return policy. Motherboards are warrantied so is the Cpu from Amd . if you installed the cpu ram heatsink motherboard and video card right you shouldnt have a problem provide you have a decent sized power supply yours seems way to low as as far as power 250?. You need at least a decent 580watt power supply. If after all that you still have problems then Rma Cpu and board for exchange with manufacturer. But first get a new power supply and try that first. here

  4. Maybe a sucking eggs thing, but have you updated bios to latest version?
    This wiki list has it as a AM2+ socket, you say have a AM2 socket?
    Aah, hang on, your Mobo supports
    *From wiki*
    Socket type: AM2+
    Motherboard supports the following processor upgrades:
    •Phenom with Quad Core technology (AM2+) up to 9600 ** (up to 95 watt)**

    and your chip is, * Also C&p from wiki*

    Phenom II X4 940 Black Edition2 C2 3.0 GHz 4x 512 KB 6 MB 1.8 GHz 15x 0.875 - 1.425 TDP >**125W**< AM2+ January 8, 2009 HDZ940XCJ4DGI
    I'm voting your Mobo doesn't support it due to the thermal limit.
  5. Thank you for all your kind replies guys. I still have one last question. I'm fairly (Still learning) about computer hardwares, and my inquiry on power is will any power "supplier" fit into the motherboard? I have never dealt with any power "supplier" before so i want to get this right before i change it.

    And i found out just now i can RMA refund (subtracting any additional fees) from my original grand total to exchange for another newegg product. Will any kind souls recommend me another similiar am2 CPU that will run any present mmorpg games?

    Thank you sincerly.
  6. Cpu seems good. If you need a new motherboard just make sure you get an msi motherboard there very stable and darn near bulletproof. For power supplys eighter An Antec earth watts 750watt or a Corsair 750 power supply. Good luck
  7. For extra information, i'm running AMD sempron processor Le-1200 2.1GHz with 45w and for graphics, ATI Radeon 5700 Series.

    Sorry, they wouldn't let me edit my earlier message.
  8. I believe your motherboard only supports 89watt cpus from what I have read so far. This would be a moderate upgrade over your current cpu witthout breaking the bank:


    You definitely need a new video card too:


    I personally would like to see you upgrade your psu. I have to go to work right now so I don't have time to research about you case accepting any standard power supply so try to google for it in the meantime until someone else answers or I get back later this evening. You don't need a 750 watt psu.

    This will be plenty and is more like a 550 watt psu.

  9. Thank you for your reply englandr753. I will try to install a more powerful PSU today to see what's going on. If it doesn't work then that just means i have to RMA refund for another hopefully similiar/working CPU. I will update asap.

    Wish me luck.
