Strange happenings

[gambler47]

I am having a nightmare with this problem. I have put together a new 'puter for my son. I have a NEW case and power supply, NEW Celeron 1.1 ghz cpu, a NEW motherboard. This is the third motherboard (Amptron M756t+) from the manufacturer. I install the MB with 5 of the brass (or copper) stand offs. The problem is when I turn the system on I get almost nothing. The power supply fan comes on, and the cpu fan comes on and that is it. It will not turn off from the front switch and will not reset, the CD trays will not open, no power light, no video, no floopy,no nothing. I have put a volt meter to some of the power supply connections and I have voltage. I don't understand why the cd trays will not open when their is power to them. I am at a total loss of why there is nothing happening, not even any beeps. This thing is one step from a 12 gauge thru the side panel. Please help I'm going crazy.

<<. . . not even any beeps>>
All you need for any beep is: CPU inserted correctly and a speaker connected to the board. Hence: no beep, mobo may/must be dead.

But hopefully somebody will prove me wrong!

Not even any beeps. Nothing except the cpu cooling fan coming on, the power supply fan coming on and that is it. The floopy drive does not even spin up and the cd trays will not open. Cpu is socket 370 Celeron 1.1 gig. I kind of agree with you that the mobo is dead the 3rd one. Should the mobo be connected to the case? It is lifted away from the case by 5 brass stand offs.

Yes this sounds like my mobo except for the latter info. It supports Celeron up to 1.1gig I THINK. But to make sure I removed the 1.1 and put a 366mhz Celeron on it and plugged the cpu fan in. Same results, no nothing.

Hi,

>> This is the third motherboard (Amptron M756t+) from the manufacturer.

Does this mean that the two previous boards were knackered too?

Gambler - << . . . brass or copper stand-offs>>
I may be wrong on this one but shouldn't they be plastic ones? However, I suppose it depends on mobo.
Anyway, have a look at this link (http://www.pcmech.com/byopc/step/9/) which may help you with correct installation.
Good luck.

Yeah 3 doa's. I have but 'puters together starting with the antique 286 with a whopping 2 meg of ram (G).I guess I should just trash the board and get an ASUS or Biostar. I've have great success with Asus which is recommended by AMD.

Place the MB on a piece of cardboard or any other insulating material.
If that works, then the MB is shorting out and you will have to place paper washers between the MB and the standoffs and fasteners.

[bennyt]

Well, I guess at some point alarm bells should start ringing... http://www.PCGuide.com/ubb/smile.gif
I imagine any make of mobo would be an improvememt. lol

Good luck,

Hello Gambler

I'm using diagnostic flow charts.
1. I assume the PC is not dead because you have fans working.
2. I assume it appears that POST did not run and that there were no audible beeps. This is, therefore, a POST problem.
3. I will assume that the power supply voltages are correct.[test if possible]
4. Disconnect all peripherals and system adapter cards except the keyboard and monitor.[After switching off and disconnecting from the power source naturally]
5. Boot the PC and if POST still does not run you have a faulty system board.[Only if your power supply is good]
6. If it does run; re-connect the floppy and run advanced diagnostics if you can and test the system board. If the system board fails the tests then it is faulty. If it passes the tests then:
7. Switch off, re-connect one peripheral or adapter card and reboot. If post does not run then this last item is faulty. If it does boot test this last item with the diagnostics software. If it fails the test it is faulty.
8. Repeat step 7 untill all items are reconnected and re-test the whole system.

If it still does not function send me an Email.
