new box not booting

[CujoRbd]

Here's what I got:

Aspire ATX mid-tower with 350W PSU fromNewEgg
AMD Athlon 64 3000+, from NewEgg as well.
ASUS K8V with Via chipset
512MB of Kingston PC3200 DDR, 400 MHz BUS from Outpost.com for $90, thanks to MDS.
ATI Radeon 9600 video card
Creative Soundblaster Live 24-bit PCI sound card
I also have a 40gig HD, which I am currently using on my old PC.

So, I installed everything except the soundcard, because the mobo has built-in sound.
My main problem right now is that I receive no POST. However, I did start it up successfully once earlier. Also, the case came with a couple fans, a few LEDs, and an LCD screen for temp readout, which I haven't been able to get working either.
When I successfully booted up previously, none of the extras were hooked up.

I wanted to get the fans, etc. all hooked up as well, so I checked Aspire's website to see if they had some instructions for the case (it didn't come with any). All they had was a Word document, and I don't have Word. I was able to read the text contained within, but there may have been some sort of wiring diagram which I was not able to view.

I'm so frustrated at the moment that I can't think enough to know that to do next.
Any help would be appreciated. TIA.

The basic procedure is to place the board on a non-conductive surface and install the cpu and fan, 1 stick of ram, video and connect the power supply. If it will boot then put the board into the case and add one part at a time until everything is installed or you find the part that prevents the boot process.

Ok, so it worked before you plugged in all the extras? Have you tried booting it again with all the extras unplugged? Sounds to me like the PSU can't handle the load. Also, the PSU that comes with that case is CRAP anyways. You can get a really good PSU for $40. http://www.newegg.com/app/ViewProduc...153-006&depa=0

Thanks for your quick replies.
I went ahead and tried your method, Elroy, and I still get no response. The CPU fan doesn't even spin. There's a standby LED on the mobo that is on when the PSU is, but other than that the PC seems dead.

I have the mobo, with CPU & fan, the memory, and the video card. Without the case (which has the power switch), how do I initiate booting?
Also, I should have the 12V ATX power connector as well as the main power connector attached to the mobo, right?
There is another power connector, but it looks like an AT. Knowing that the PSU is ATX, why would it have an AT connector on it?

Something I just noticed when comparing my case to the pictures at NewEgg, mine seems to be missing something. There's a small circuit board attached to a power connector in this picture. I don't recognize it as a necessary component, but what is it and should I have it?

Thanks again.

the extra 6-pin connector is for xeon boards i believe

try contacting newegg to see what that part is, i have never seen anything like it but you never know you could need it

[CujoRbd]

OK, thanks HeadBand. I went ahead and emailed NewEgg, but have yet to receive a response. I've also contacted Aspire; no response either.
A burning question in my head is this: Can I turn on the PC without the switch on the case? And, if so, how would I accomplish this?

Thanks again, TechIMO members, for your help.

The front panel connectors on the mobo, (refer to the manual) are what sends a signal to the power supply to start up.

The two PWR pins need to make a two second momentary contact, like pushing the pwr button. 4 second contact tells the mobo to go into sleep mode.

You can start it by shorting those two pins (PWR) with a screwdriver or, hook up the PWR leads from the comp, and push the button, if you want.


Usually this layout, short the (pwr/pwr) pins:

(led/ledpwr) (pwr/pwr) (no pin)
(led/hddpwr)(reset/reset) (pin9empty)
