P5E3 PRO - no signal

Hello I am having major difficulties getting this system up and running. I am running an ASUS P5E3 PRO and I cannot even get it to show a BIOS screen.

Honestly I'm not sure how I had my system set up before but apparently I don't have a system/case speaker so I can't tell if my system is beeping at me. But the fan for my PSU, CPU and current (and past PCI-e) cards are spinning, my ram is definitely seated properly.

I started with an Nvidia GeForce GT 220 512MB, then after wasting a whole painful day I decided that the card must be faulty -- returned it the next day -- same problem -- called the company that makes the card they said that the CrossFireX is an ATI thing so I replaced this new card with an ATI Radeon HD 4350 --- still no signal to my monitor (Acer x241W - DVI, and VGA no signal) - I even tried connected it to my HDTV via HDMI and still no signal.

Is it possible that this motherboard is faulty? I get a green light when my PSU is connected but no beeps -- should I just go and get a computer speaker so I can get in tune with whatever the comp is trying to communicate?

This has been giving me so much grief and I'm starting to think it may be my motherboard.

Can anyone offer me any suggestions? -- I should note that I don't own any other monitors but this Acer monitor (with DVI and VGA does work with my other computer (MacBook Pro 17" DVI - 1920x1080 native).


Thanks in advance!

  1. I should mention I have reset the CMOS and taken out the battery for over 30 minutes to no avail.

    My card is a PCIe - x16, 2.0 - and it doesn't require a 6-pin power connector. (ATI Radeon HD 4350)

    Would it be possible that this MB needs a card that requires 6-pin power?

    Thanks again,
  2. Do have a system speaker - that thing that makes the beeps?

    If not, because your build is not working, you really need one.
    Where to buy a small motherboard speaker

    An illuminated motherboard LED does not mean much more than the PSU is plugged into the wall and the PSU is switched on in back.

    First, try to check out the PSU. The best way is to replace it with a known good PSU of similar capacity. If you have a multimeter, you can check all the outputs. Yellow wires should be 12 volts, red 5 volts, orange 3.3 volts, blue wire -12 volts, purple wire is the always on 5 volt standby.The tolerances should be +/- 5%. If not, the PSU is bad.

    The gray wire is really important. It sends a control signal called something like
    "PowerOK" from the PSU to the motherboard. It should go from 0 volts to about 5 volts within a half second of pressing the case power switch. If you do not have this signal, your computer will not boot.

    After that:

    After that, pull all the parts out of the case and breadboard the system, building it step by step:

    Oh, and please post system specs.
  3. I'm having a similar problem with my P5E3 motherboard. Seems to power up OK, but no video. I also tried different video cards, monitors, memory. resetting the bios, and removing the battery, changed the power supply, removed all peripherals, drives etc. ...

    I'm wondering what ever happened with this problem.
