Hello there, I am one very annoyed person.
Nothing works on my home built pc.
specs are ;- Asus A7V KT133 mobo w/o audio, AMD Athlon T'bird 1Ghz Processor, 256Mb PC-133 SDRAM, Geforce 2 Ultra graphics card, a 9.5Gig hdd(sory cant remember the name of it), a soundblaster 1024 live pci soundcard
these are all nicely placed in a ATX midi case with a new 430W power supply unit.
I plug everthing in, turn the switch on the psu, press the power switch on case and.....nothing!
Theres power there cos the speakers get power from the psu and they work.

My old crappy comp worked better than this, bloody computers, damn them all to bloody hell!

Well before you start pounding your fist into the sand http://www.PCGuide.com/ubb/smile.gif
Check that the "soft" power switch to you motherboard is installed correctly. Also check that all your drives are connected right and that you have pluged in the power connectors in the right order.( For example if a line has 3 connectors on it. Make sure that the first connector is used , then the second and so on. If you use the second connector but not the first the system will refuse to power up.)

Good Luck http://www.PCGuide.com/ubb/smile.gif

Cheers, I will check to see how i attached everything, too late for the sand thing though, I found walls are much better and have a lasting effect too http://www.PCGuide.com/ubb/smile.gif

OK I tryed many various settings for the power cables and still not a sausage happens, the mobo's PLED comes on to indicate the soft power is there, but no fans are kicking in or anything.....oh bugger it, anyone got a baseball bat http://www.PCGuide.com/ubb/wink.gif

Could be a short in the system. I heard people here suggest taking the MB out of the case and then try to power it up. I think you could even place some cardboard pieces between the MB and the case. Then give it a try.

Other than that the only other time I've had this problem is when I fried a processor.

Hopefully someone here will have some other ideas.

I think the best thing to do is take the whole system apart and start again from scratch.

Once you have done this, try setting up the motherboard out of the case with the bare minimum of components (memory, processor, video card and speaker). Now attatch the power supply and fire up the system. This should be enough for the system to perform a basic POST. If you don't get any sort of response then you know one of these components is to blame. (also try listening to the speaker and note down any error codes)

If this does work, then put the board in the case and add each of the other components a piece at a time.

I know this seems like a very basic solution but very often thats all that it takes!

I give my complete attention to a very good friend of mine.

It sounds like your MB is grounding out. Make sure you have spacers between MB and case. What scada said checks for this problem.

Good Luck!

------------------
I was called "hacker" before there was a HeathKit.

Computer shops have cardboard washers to go between the motherboard and chassis that solve grounding problems quite nicely.

I agree with scada and TVC15 that it sounds like it's shorting out somewhere, commonly called grounding...something on the motherboard is grounding against the chassis.

Are you absolutely sure you have the two-wire connector for the front panel off/on switch connected right?

It goes here:

yes the on/off switch is on the correct place and as for the grounding thing, I'll try taking the thing apart (don't really want to but will give it a shot)
thanx for the help people, I hope to have it solved shortly and be happy once more that my computer works

yes indeedy, having taken the whole system apart and reassembled and clearing the CMOS I now have a working computer again...however, my modem causes/caused the power supply to cut out so as not to fry it and the other things so I still have no modem(I can live without that for awhile I suppose) and also I appear to have no sound. The sound card is there, its detected but no sound...bit of a downer there but I will reinstall the software and see what happens, if nothing happens I will get it exchanged at the shop I bought it from.

Thanx for the help on this guys, its much appreciated

Double check and make sure that the speakers are plugged into the correct spot on the card, also are the speakers powered or not? If they are poweredare the correctly connected?

I was working on my father-in-law's machine last night and got the speakers plugged in wrong ---no sound! Some sound cards are color coded so check the manual to see which connector is which. They all tend to use different colors for the connectors.

Yup, everything is plugged in the right places and the speakers have power I just have no sound, I tryed removing the card properties and reinstalling them and still no sound.

I just think its shagged
same with the modem

The modem and sound card problems are nuisances, but minor compared to getting the system back up. Congratulations, give yourself a pat on the back!

Check Device Manager for conflicts. Modem and sound could be trying to use the same IRQ, probably 3. If it's IRQ 3 remove the sound card, then remove it in Safe Mode, shut down, reinstall it, maybe in a different slot, reboot and let Windows find and install it. The modem should probably stay on IRQ 3, that's COM2 and 4. Sound cards usually like IRQ 5, but sometimes will take a different one.

If it's the other way around, remove and reinstall the modem.

To see what IRQ everything is using, highlight Computer in Device Manager and click Properties. That will show a list of used IRQ's. Any IRQ not shown is free.

You might also be able to simply reassign IRQ's, that will often work too. Go to the Resources tab for the device you want to change, and uncheck the "Use Automatic Configuration" box, then you can change resources. Watch out for DMA and I/O if you change the sound card around, that can open up another can of worms...

The sound card is in the bottom PCI slot on the motherboard where it always was and it use to work, maybe its fryed or something, and the modem simply causes the PSU to cut power so as not to fry the other components, so it got taken out.
Also I have tryed moving the sound card to another slot and still haven't a sausage of sound, this led me to believe that the card was fryed.
The card goes back to the computer shop I bought it from as soon as I can get there.
