Hi,

Of all the computers I have built this is the first time I have had this problem.

When I push the on button, nothing happens.

This is a new build for my wife, and she's patiently waiting for:

Gigabyte GA-P35-DS3R motherboard
Intel E6750 CPU
2GB G. Skill 6400 memory
MSI NX8600GTS vid card
Seagate SATA2 160GB HDD
500W Cooler Master PSU

The problem is when I try to turn it on, nothing happens.

I checked the PSU with an Antec tester and it seems OK, I even tried another new PSU with the same result.

I noticed, however, as I unplug the ATX connector I get a brief start of the PSU and case fans. I've double checked the ATX (20+4 pin) orientation and pin configuration to no avail.

Any thoughts?

have you tried setting up all the hardware outside of the case on a piece of cardboard? you might be grounding the board somewhere on the case

OK, it's in a Cooler Master ATCS case with a removable motherboard tray. I tried it with just the CPU,memory, and the vid card.......it works!!!

Now, I'll start adding parts one at a time and see what happens.

Thanks,

That didn't go so well. I added the HDD and it started OK then, I tried a floppy and it would no longer turn on. All of this was done outside the case on a non-conductive surface.

I'm back to the vid card and CPU, and memory, it won't start anymore???

Well, I think the motherboard has a problem.

I got a floppy, a SATA burner and harddrive to work long enough to Fdisk and then install XP Pro.

I then installed the drivers for the motherboard and video card, rebooting as required. Next, I let it idle for a while then shut down and added the second harddrive. Now it won't turn on. :)

It's a cheepo Cooler Master 500 watt, I am running again now on a 450W with some stuff unplugged.
I just ordered a 650W, maybe that will help.

I have the second HDD in, but I had to pull the plug on the USB ports for the card reader and two case front USB ports.

I just tried to plug in the two case front USB ports and it was a no go, unplugged and got it to boot up.

I solved one problem......ME. When I plugged in the connectors for the case front USB ports, I had them backwards. Now, I can boot up with this 450W PSU, next I'll try the 500W Cooler Master again. I wish I could get it to work because I spent a day sleeving it all blue and silver. BTW, it checks out OK with an Antec PSU tester.

Yeah, you got to watch out for those ones! :) I should think the Cooler Master 500W would be alright, it's a good brand manufacturer.

When you say it boots up now, does that mean everything seems to be going sweet - no other errors?

I'm running with 2 SATA HDDs and a SATA DVD burner on a 450W SAGA PSU right now, but I have yet to power up an ATA DVD drive. I still want to try the 500W Cooler Master PSU when I am up to switching things around again.

Well, I got everything set up and working on the 450W PSU, and today I tried the original 500W PSU and everything works. My only conclusion is that I must have had some faulty connections which, after plugging and unplugging things so many times, are now working. :)
