Another POST'ing problem!

tristala · 1 Jul 2007 at 22:37

Hi Guys,

Bought My new PC bits from OC about a month ago and has been running wonderfully up till today!! The PC went to sleep after not being used for a while and now.... nothing! All fans seem to power up, including the GFX card but I get absolutely nothing output to the monitors!

I don't have a case speaker attached, so if anybody could point me in the right direction of where I might be able to buy one that would be great, or if anyone has had a similar problem and found a solution this would also be useful.

My spec is as below:

Asus P5N32-E Plus Mobo
Intel Q6600 processor
Leadtek GeForce 8800GTX 768MB
OCZ (2x2GB) 667mhz RAM

The system hasn't been overclocked at all and I've tried reseting the BIOS. Unfortunately I don't have a spare rig which I can use to test each part individually

An help would be greatly appreciated..

Thanks in advance.

Hi huddy,

Thanks for the reply, I have the Corsair HX 620W psu. This evening I have completely stripped down the PC and rebuilt to make sure nothing had come loose, but unfortunately no joy

I've ordered a speaker to connect to the motherboard which hopefully should shed some light on the situation and am trying to borrow some RAM off somebody to see if thats where the problem lies.

I'm pretty sure power isn't the issue as everything powers up when I hit the power button. For when I do get the speaker attached, how generic are the POST codes? Do I need information for my specific mobo/bios.

Once again thanks for the help, hopefully it will be as simple as faulty RAM, so it will just be a waiting game once I get an RMA and send it back.

Ok.. an update

Just thought I'd post an update in the hope that someone can help.. as things just got weird!

After Huddys advice and checking everything, I borrowed some memory from a mate, stuck it in, and bing! everything comes to life an works nicely (apart from running Vista x64 on 1GB of memory...slooooowwwww).

Great! I think then I must just have some faulty memory but to be sure I'll check it again, so one at a time I check each of the DIMMs. First one.. wow!.. everything works ok .. maybe I'm just being stupid.. try the second one.. nothing... excellent I've narrowed it down to one of the sticks.

Next step.. one final test before requesting an RMA, take it into work and try on a machine there... would you believe it .. both sticks work!

So there seems to be a problem between 1 of the sticks and my machine.. anyone got an explanantion for this? Or should I jsut request a RMA and send it back. Unfortunately because it was the OCZ 4GB (2 x 2GB) PC2-5400C5 Dual Channel set I'll have to send both back and go back to my old pc while I wait

So if anybody can advise on whether I should just stick them back in the post or that I'm missing something obvious ..please let me know.

thanks in advance

Hi Deaddude,

If I put the "faulty" stick in the machine it won't boot at all, it gets as far as powering up, but never gets past that, so the fan on the graphics card is going at full pelt but just stays like that! So I wouldn't be able to run any kind of diagnostics on the memory

Any other thoughts?

I think I'm gonna have to send it back, but my fear is it will be tested on return and work fine, thus leaving me out of pocket having had to pay for the memory to be sent back to me and then having to buy more to replace the stuff that won't work in my machine.

Hi Huddy,

Sorry if I sound stoopid here, but I'm presuming you mean put the memory in the machine that worked and run memtest on there?

The machine hasn't been overclocked at all and all the bios settings are as default, but i'll try doing a rest to defaults jsut in case something has magically changed

Hey Huddy,

Ok, heres what I did! put both sticks in the machine that seems to work ran memtest and eventually started getting lots of errors coming on the screen. But though it might be an issue with the board not supporting 4gb, as it was only showing 3gb as being available. So I took the good stick out, leaving just the suspect one, reran memtest, no errors! But when looking in the BIOS it was only registering as 1GB not 2GB, quick check by putting identical working stick in.. 2GB registered! So it looks likes one of the sticks is only half working.. which can't be right

RMA time I think.. just hope the turn around is quite qucik! Don't want to go back to my old pc for long! LOTRO just doesn't cut it on there

Thanks for all your help
