No Post Beeps

Hello All, I have a P4 3Gh 2gb of ram, 1 x 80gb ata hard drive, cd rom, floppy & a EQS motherboard that I'm trouble shooting. While in the middle of working on a word document the system failed...No warnings no messages just stopped.

I unplugged it, let it rest for a few minutes and then restarted it.

Power supply fan started, Cpu fan started & Case cooling fans started...but no post beeps and notting else happened. I tried to boot to safe mode, no joy, tried a reboot with floppy in, nothing...I can't detect any activity on the hard drive either by led or feeling it for vibration.

I don't have a second power supply to swap with it, but will get one if needed. Any suggestions before I purchase a new power supply. Oh the motherboard is only about 15 months old, but the P4 processor is about 3 years old.

Cheers

 

Thanks Steve...you've confirmed my suspicions...I'll purchase one and see if it corrects the problem.

 

Changed Power Supply

Hello All, I have just changed the power supply and no joy same symptoms exists...any suggestions????

Thanks

Yeah...cleaned the heatsink & fan of all dust bunnies (he he I like that one) same problem...Is there a way to check the motherboard for failure? power is going to all attached components, ie.. mouse, keyboard, cd drive (which spins when I put a cd in it) & hard drive seems to be purring....

 

Nope...was very clean as I had only cleaned it about 6 months previous.

 

Apart from removing RAM, cleaning contacts and blowing out slots and reinstalling carefully, I'd also re-seat all cable connectors both on the board and drives. Then I think Steve's suggestion of a fried CPU could be next on the list. Neil.

 

Okay...sounds like a plan..I guess a P4 3.2Ghz cpu is cheaper than a motherboard..I'll let you know how I get on...anyone out there got a intel P4 3.2Ghz 478 socket cpu they want to off-load??

Thanks

 

I've just reset the BIOS, no change.
I've tried a few combinations of ram, no change.
I've even left all ram slots empty (in an attempt to get post beeps) no change.
I've disconnected the hard drive, no change.
All connectors are sound & the system is dust free.

Sooo is that a CPU failure or a motherboard failure??? is there any way of telling for sure??? if not I'll chance all gut feelings!!!

Cause if I purchase a P4 CPU @ approx (€15 second-hand) and its not that, I'll have to purchase a motherboard..it's kinda getting expensive... I know I know thats life..but if I could minimise the expense that would be great.

Ohh yeah I forgot to mention I removed the processor and had a look at it to see if there was any signs of "Frying" everything look clean.

 

still thinking about this ... but in the meantime, have you inspected the mother board very carefully looking for any small component that looks like it overheated?

The minimal components necessary to very barebones configuration are the PSU, the mobo, and the cpu. The next level is adding 1 stick of memory with nothing else connected.

You mentioned that you tried this with no memory, I am assuming with 2GB that you have two stick of memory. have you tried with just 1 stick? You may even want to alternate and try with each stick independently. I have had that problem before.


Perhaps you can find a cheap processor that will fit in your socket that can help you isolate the offending hardware item.

In the states some stores offer discrete testing (i live in the the third world now; mexico) for components. I took my components into a PC-Club and they tested the power supply, the memory, the cpu for a nominal charge.

 

Okay people...got myself a known working processor, fitted it & no joy!!! Dang... It's got to be the motherboard Right???? all suggestions weclome...

Cheers...

 

don't rule out the power supply and / or a bad connection or cable ... it is possible ... remotely ... but possible.

Is there a way you can test your power supply? Do you have another machine you can stuff it into to see how that machine behaves or someplace you can have it tested?

You can look online at your motherboard specs (the same as most other boards) and then see if each pin of the power supply is doing its job.

Also check to see if you have any lose screws that may have lodged underneath the mother board that is grounding a portion of it with the chassis. That's happened to me before and it was a "bitch" to figure out. Actually i didn't "figure" it out until i lifted the mobo of the case and saw the bolt laying there.

 

Hi wiz, yeah I have purchased a new power supply and checked all connections...however, I will check to see if there is a loose ***** under the motherboard...

Thanks

 

hope that works.

now i have my own "woes" ... my mother board went south.

It is still under warranty but its a pain to send it in and hook everything back up.

i have an evga 780i and it's dying during the POST at error code C1 which is memory detection. The memory is good.

Bleeding edge technology is great but it has kinks. This is the fourth board i've gone through in a little under two years.

I started with a 680i.

EVGA has great support. I think that the problems are more from the NVIDIA reference specifications or blueprint or whatever they call mobo design these days.
