You really did this?
If so, you have already spent more time on this board than Soltek did.
Try POSTing the board with only CPU, RAM and video connected.
Then it's just a process of elimination to see what has failed.

yup i did that like i said it made the voltages ok in the capacitors. what do you mean by POSTing... i remeber this term but i have forgot, is it power on self test ???
Re: Computer does not power
Yes.
Basically, you want to get rid of anything not needed to get into BIOS (i.e. HDD, CD-RW, etc.).
This will require that you have spare/replacement parts to substitute, however.
It might be simpler if you just try your RAM/video card/CPU in another PC...if they work then you're down to the motherboard.
Re: Computer does not power
ok thanks, how does the POST test work, what do you have to do...and what results can you expect if the POST is successful?
Re: Computer does not power
If the POST is successful then you see the initial startup screen with bios access.
If it attempts to POST buit gives a sequence of beeps you may be able to work out what's wrong from the beeps.
Edit: you don't have to "do" anything except power on, that's why it is called a power on self test. :rolleyes:
Re: Computer does not power
aha! thanks lynx will carry out the test and let you guys know.
thanks again lynx and clocker.
Re: Computer does not power
hey, i am back, i have conducted the POST test and nothing,i pressed the power switch and the computer does not turn on. just for verification i have checked the power switch and that is working fine.
does anyone know what i should now...new motherboard?
Re: Computer does not power
First thing to do is check the PSU. If no fans are turning there may be a problem with it, even if you've replaced it. I'm at work atm so I don't have time to find a link to show how to test it, maybe you can search for that or someone else could post a link.
Re: Computer does not power
To test the PSU (like Lynx suggested), first unplug the psu from your computer and take it out of the case.
Next you need to plug the PSU into the wall and then short the green wire on your 20pin ATX connector (the set of wires that plug into your motherboard, has 20 wires total, you won't miss it) to a ground wire, not sure if it matters which but the one right next to it to the left side is one I know works.
Here is a picture taken from this guide which might also help you, altho you don't need to follow all of the steps shown in that guide.

edit: a peice of wire with both ends stripped to expose some wire would work for this, don't bother cutting the wires.
What will happen is the PSU fan(s) will start to spin, showing that the powersupply is on.
If the fan doesn't spin then something is wrong with the psu.
Re: Computer does not power
Thanks Ross, that's exactly what I meant. I just got in a short while ago, and this is the first chance I've had to look in here.
Re: Computer does not power
UPDATE:
hey fst. right after some test it was evident both the psu had failed and the motherboard had been flashed.
this left me no option but to purchase a new motherboard and psu. i have bought both these and can tell you the computer is working. i have to reinstall windows ( it comes up with blue screen of death about new hdd controllers..but i was going to do that anyway. so installing windows xp pro ( :) ) at all should be good!
