Replaced motherboard & pc won't power up

Recently I recieved an error message that "cpu failed test". I replaced motherboard, cpu etc. When I hooked everything up again there was no response when power supply turned on. Green light on motherboard comes on, but when I press on/off switch....nothing. No fans..nothing. Any suggestions?

    Hi,
    Thanks for reply. Followed instructions...still no response when on/off switch pressed.

    Have you tried substituting another power supply? Just a thought. New MB and new CPU right? Also try using the other piece of Ram instead of the ne yuou are currently using. It should be in the slot closes to the CPU.

    Take the MB  out. Unhook everything except one strip of Ram and the PS and case wires. See if it will boot now.

Motherboard replacement


Kind of a major deal since all cards and drives need to be unplugged, the old MB pulled, a new one (with CPU) inserted and all cards, drives, etc hooked up again. Before you do this look at the age and condition of auxillaries. Often it is time to upgrade power supply, hard drives, etc. You may be better off with a new system. Try www.directron.com They sell MB with CPU (tested) or complete systems

Laptop beeps 7 times


Try link: http://blog.parts-people.com/2014/06/27/dell-inspiron-m501r-m5010-beep-codes-diagnostic-indicators-2/ How to identify beep codes: When a laptop or computer first powers on, it goes through an initial set of diagnostic tests to make sure vital components are preforming correctly. These tests are called POST or Power On Self Test. When a test fails, the user is notified via POST codes, Light codes, or Beep codes. For diagnosing Beep codes you need to:
  • Power on the laptop or restart it if it is already on.
  • Listen to the number of consecutive beeps when the computer begins to boot. Restarting the laptop may be necessary and should not harm the laptop at this time.

  • 7 Beeps: Reseat or replace the CPU or replace the motherboard.

Replacement motherboard not rebooting


If you did not change the CPU the the BIOS is not seeing it correctly. You can update the BIOS or you should be able to press F1 to continue to boot.

1 long beep 2 short beeps


Hello Hardyjosef,
Below is the beep code chart for the mini 10 systems.
No POST
If the system does not perform a Power-On Self-Test, there are various things to look for:
1.Check that the system has a power light.
2.If the system has no power light, ensure it is plugged into AC power. Remove the battery.
3.If the system has power but is not performing a POST, Check for one of the following Beep code errors.
Beep Code Description Failure Coverage
1 BIOS ROM checksum in progress or failure. BIOS Chip Motherboard Failure or ROM Error
2 No RAM Detected No Memory Detected
3 Chipset Error (North and South Bridge Chipset, DMA/IMR/Timer Error for Intel platform); Chipset Error Motherboard Failure
Time-Of-Day Clock test failure.
Gate A20 Failure
Super I/O Chip Failure
Keyboard Controller Test Failure
4 RAM Read/Write Failure Memory Failure
5 RTC Power Fail. COMS Battery Failure
6 Video BIOS Test Failure Video Card Failure
7 CPU Cache test failure CPU Failure
8 LCD LCD Failure
4.With the power off and the system unplugged, remove all CRUs from the system and reconnect the AC adapter to the system and try again.
Try reseatting the memory to see if that will resolve the issue. If not, the motherboard may be bad and will need to be replaced. If you need another motherboard you can call the Dell Spare Parts Department at 1-877-717-3355 to purchase one.
Thank You,

Yes, if the CPU/motherboard will not POST (Power On Self Test), then changing the CPU is the only thing that you have not tried.

Home built 4 yr old pc wont boot


You have voice message telling you CPU test failed , but does it BEEP at all ? if you have a Beep code then replace the CPU fan ( when CPU gets too hot it will either shut down or the PC will not boot up at all )

Try removing all PCI/AGP and RAM cards from the motherboard and disconnecting all drives via their power and ribbon cables too and see if you at least get the boot process to start. if not, that confirms your motherboard is bad.


If it does start but gives errors for the missing components, start putting them back in or connecting them back up one at a time until the problem returns and then you have your failed part.

System Restart regularly


Sounds to me like your power supply may be failing or loose connections.

You don't mention if you're overclocking the CPU. Double-check the BIOS settings to make sure things are set properly.

Another thing to check is if the CPU is overheating. Make sure the heat sink is still firmly attached to the CPU and that the CPU fan is operating.
