New motherboard that does not post
I recently bought these items from Newegg:
MB ASUS | M5A88-V EVO 880G RT CPU AMD|4-CORE FX-4100 3.6G 8M R And this from Crucial Technology: CT2KIT51272BA1339 8GB Kit (4GBx2), 240-pin DIMM When I put it together, it did not post. It has NEVER posted. When I press the power button, the CPU fan and case LED come on but I get no display on the monitor and no beeps. I connected the monitor cable to a laptop computer and got a display so it cannot be a bad monitor or cable. I tried it with two new power supplies. I tried it with two memory modules, one memory module and no memory modules. If I hold down the power button for four seconds when it is on, it turns off. I took out the CMOS battery and left the jumper in the reset position for more than 15 minutes but it still did not post. Does anyone have an suggestions as to what I can do to get this motherboard to post of how I can determine what is wrong? Thank you in advance for all replies. -- When I am in the kitchen, I often kick one of my cat's balls. After I kick it, he will sometimes play with it for a few seconds to several minutes. His favorite are the ones that rattle. He'll play with any ball that makes noise. |

"MB ASUS | M5A88-V EVO 880G RT CPU AMD|4-CORE FX-4100 3.6G 8M R" OK, let's check the BIOS compatibility. http://support.asus.com/Cpusupport/L...20EVO&p=1&s=24 FX-4100(FD4100WMW4KGU),3.6GHz,4C,95W,rev.B2G,AM3+ ALL 0707 The FX-4100 requires a minimum BIOS version of 0707. If you have another processor chip to work with, you could work at verifying the version present now. Or, if you know you've flashed the BIOS, you may have some record of what version you flashed with. If the motherboard is brand new and untouched with regard to flashing, you can look for a paper sticker on the flash chip, and see whether it is version 0707 or later. If the revision is an older one, you may need to borrow an older processor, to do the flash upgrade with. If you connect the computer case speaker to the SPKR header, remove all RAM, then there should be a RAM error (beep) code if the processor is actually able to execute the BIOS. If the case speaker remains silent, while doing the "missing RAM test", then the BIOS revision may be too old to recognize the processor. The speaker can only beep, if the processor can run code, and pulling all the RAM, is a way to trick it into beeping the speaker. But that only happens, if the processor is able to execute the BIOS code. Paul |

Have you tried hitting the reset button or blipping the reset pins on the motherboard? Sometimes doing that every 10 seconds will eventually make the computer boot. Are there any shorts between the motherboard and case? They usually occur around the mounting holes (check each, top & bottom) or at an unsupported corner (no standoff within 2"). Also extra standoffs that don't line up with any motherboard holes can cause shorts. Do you have a speaker connected to the motherboard pins? It can sometimes give diagnostic beeps even when there are no other signs of life. Is the CPU heatsink installed properly and making contact all along the top of the CPU package? Some motherboard BIOSes won't allow operation if the CPU overheats, despite all modern CPUs having built-in heatproof protection.. Some do also do this if the fan doesn't detect spin (fan may spin but motherboard doesn't see any RPM pulses from it). I normally test a new motherboard by installing just the bare minimum amount of hardware so I can see if it works -- CPU, CPU heatsink/fan, one memory module, speaker, power button, reset button, keyboard, monitor, and video. I run a memory test for a while before installing anything else. |

If you are getting no post beeps and no display it is likly a faulty proccessor?. how many watts is the PSU? |

The manual recommends a minimum of 450 watts. I was using the on-board video and had no drives connected. -- When a cat sits in a human's lap both the human and the cat are usually happy.

If you test the motherboard outside the case, be sure to do it on an anti-static, non-metallic surface, such as the foam sheet that was inside the anti-static bag with the motherboard. Plain wood is usually OK, as is a 1/2" thick layer of newsprint or brown paper bags (no shiney paper). There are no extra standoffs. The motherboard has nine mounting holes. All nine mounting holes have screws in them that are screwed into standoffs. How about the corners? Motherboards and cases can flex a surprising amount or be warped. I have a speaker connected. I used an ohm meter to check the speaker and speaker cable. I measured 17 ohms at the motherboard connector. Can a speaker fail and still measure 17 ohms? I don't know what the motherboard's speaker connector is supposed to measure, but speakers and their wiring commonly measure 8-32 ohms. I think you should hear a click or scratchy sound when measuring the speaker. The fan is plugged into the motherboard. The fan does spin. How can I tell if the fan is generating rpm signals? (I do not have an oscilloscope.) Some multimeters have a frequency (Hz) function that can measure the pulse, but in practice, that pulse is always there unless its wire is broken. If the motherboard will not allow operation because it senses that the CPU is overheating or that the cup fan is not spinning, would it leave the power supply on? Good point. I don't think so. Also a short between the motherboard and case usually results in the power turning off in a few seconds. I have a feeling NewEgg sent you a dud motherboard. A lot of times they'll pay for return shipping if you phone them rather than use e-mail or their online RMA form. |
