Gigabyte MB GA-8KNXP No POST

[tom6969764]

Been having probs with MB, it seems to work ok, but I am not getting a post beep, nor any beeps for that matter, I think I origianlly had wrong RAM in it, RAM correct now but no beeps. I have checked speaker connection and this is correct.
My question is, if I am not getting a post beep, is there an underlying problem, that is not apparent when MB boots up?

Any help greatly appreciated!

I find it hard to imagine that your post made it this far without any responses.
I dont know a great deal about the internals of computer but have had some experience.

Ive been told often that if you take out the battery on the mother board for about 5 to 10 minutes, you will reset the the bios.
You might try this as a starting point.
Not knowing much about your computer doesnt help a great deal though. Maybe you could tell us the Operating system and some other details ... age of computer, was it running well before hand so on.

Hmm so do I, 34 people read it only 1 answer, I thought this was a good forum?

I have done the battery bit, no post usually means power supply probs, but pwr supply is ok.
As I said RAM was wrong clock speed, i.e. should have been 3200 but was 2100, now have 3200 in PC.
OS does not really make any difference re MB booting up, but it was XP SP3, but I have been trying it without hard drives and just the video card and RAM to try for a POST.
Age not sure, immaterial probably, skt 478, 3.2GHz processor, 800 FSB, ok for MB as long as with 3200 RAM.
I am now looking for a silent boot option but can't find it with this version of BIOS.

How are you sure the PSU is OK ? ?
Have you tried it with only one stik of RAM ? ?
Have you pulled the MBoard from the case and tried it ? ?
For this hook up only PSU; CPU and fan; 1 stick of RAM; monitor; keyboard and mouse.

Thanks for reply, I have tried 2 PSU, one new, both start I have put a power supply tester on them and and all OK there (i.e.+3.3, +5, +12 etc)
Also tried with one stick of RAM, in diff slots.
I have tried with just min i.e. 1 RAM, CPU, KB & Mouse & monitor, also with nothing but CPU & RAM to see if I get audible beep.
I did think it was the MB shorting on the case but I have tried a new case, and it is only on the brass pillars so should not short.
The only thing not tried is taking MB out and putting a piece of card underneath, but as it is not touching the case because of the pillars that seems unnecessary.

Thanks for replying Patio. You certainly are a better candidate for solving this issue than I, anytime.

tom6969764,  is this a new build or a working computer that your working on?

[tom6969764]

Was a working PC, but after instillation of XP SP3, it started to pack up. Not helped by the wrong RAM I guess, anyway now trying to start again with new install etc. but I am worried that lack of POST is indicative of another problem that I have not found yet.

The best test at this point to determine if it is the MBoard ias a bench test outside of the case...

[tom6969764]

Thanks, what is the best way to do that?

Yes I have tried just one stick of RAM & 2 diff bits as well.
Yes I have hooked up just PSU, CPU/fan, 1 RAM & keyboard & mouse.
Same result.
The only things not done is remove MB from case and try it out of case, how would this help?

Out of case test>Shorting case to board

[tom6969764]

Ack, will do. I will post back when done with result.
