Nothing happens when I hit the power switch..

Had a problem with the DIMM2 and DIMM3 slots on my motherboard not working, sent it back for an RMA and now I can't even get it to power on.

Short version, got it down to just the CPU, video card, 1 ram stick, and the power switch installed. Tried swapping the ram stick and the vid card. Tried re-seating the CPU. Checked to make sure CMOS jumper is in the right spot. When I plug in the power supply, the LED on the onboard LAN lights up, so I know the PSU is working, but when I hit the power switch nothing happens. Pretty positive I've got the power switch hooked up the right way (and tried it both ways), yet still nothing.

the board isn't shorting out on a stand off or anything is it?

its helpful when when you post a help question you list system specs.

Vcize,

Perhaps the power button is flakey.
Try removing the connector from the MB and just shorting the pins together momentarily with a screwdriver.

Some boards require that the cpu hsf be plugged into a specified header or the board wont boot. If your board is like that and you plugged the fan in elsewhere, that may be your problem.

Tried it sitting outside the case on a tshirt and it still didn't work, so I don't think it's shorting out.

Specs are:
Athlon XP 2600+
Epox 8rda+ mobo
2x256 PC3200 Corsair XMS
80gb WD HD
120gb WD HD
Geforce GT6600
TrueBlue 480w

Currently testing it with just 1 of the sticks of ram, the CPU, and an older Ti4200 video card that I know works.

Just double checked, it is indeed plugged into the header labelled "cpu fan" and still will not boot.

Good idea, how exactly do I do this? I'll do a google on it when I come home and see if 5 can find anything as well.

Try holding the front panel power switch down while cycling the ps switch in the back.

Make sure the voltage selector on the ps is set right.

Well, the other power supply I had has a 24 pin connector, the motherboard is a 20-pin connector so can't try there.

I don't know what to do, don't have another cpu, case, or PS to try to figure out what the problem is.

Did you try a CMOS reset? I know you checked to make sure the jumper was in the proper position, but you didn't mention actually resetting it.

Does your mobo support older CPUs via a jumper? Just curious, because mine does. Make sure that if it does, it is in the proper position also.

And as CrispyFried mentioned, make sure you're set to 115v on the back of your PSU.

If you have any front-USB-port wiring plugged onto the USB3 header, unplug it as a fact-finding step too, because Pin #10 is hot 5V, not ground like lots of front-USB cables are wired for, which can cause a short. And your ATX12V cable is plugged in, right, the square 4-pin one?

HEY

I just had EXACTLY the same problem.

Disconnected things one by one.

No luck.

U N T I L
[Do you like the drama?]

Disconnected the header cables as suggested above.............
It works now.

Now to plug in one by one till I find the culprit

Make sure your motherboard isn't directly mounted to the case. Usually you need washers or something of that sort as a buffer.
This could short out the system.
