Earlier today and for the past while my computer has been working perfectly fine; not lagging or randomly shutting down or anything suspicious, but today, after I moved my computer to a different room, it refused to start. So I figured it was probably just the outlet there or something and moved it back. Still nothing. I've opened it up, checked all the plugins to make sure they were secure, tried starting it without the graphics card, tried everything I could think of or find in forums but to no avail. I installed a new graphics card a couple months ago but its been working fine since then and thats the only real change in since I got it so I'm at a loss as to what could have caused this problem. If you need any more information on the type of computer or graphics card or any other specifications feel free to ask and I'll answer to the best of my ability. Any help would be greatly appreciated.

I would try these in this order:

Verify that the power supply voltage switch is set correctly. If you accidentally changed it while picking up the computer and moving it, it's possible the computer wouldn't turn on at all. (on the back of your computer)

Check that your power supply is working. Although if it went out, you should have heard/smelled it when it failed.

It's possible that the wiring from the power button to your motherboard was loosened, check that.

Lastly, it could be motherboard failure. Not sure the best way to 'test' a working motherboard if you don't have spare parts laying around.

This of course assuming that you didn't have it plugged in to a power strip or something that was accidental turned off or something along those lines.

Not sure wehre the voltage switch is, it should be on the back by the plug in into the power supply but all thats on there is the fan and the plug in so not sure where to look for that

fuse looks fine and i didn't smell anything so that doesn't seem to be the problem

checked that
even got a can of air and made sure there wasn't any dust or anything in the connections

i don't think it would be a motherboard failure because all i did was move it to another room and back, it was perfectly fine before that

I've never seen a voltage selection switch that could be moved by accident. If it's a newer machine, the power supply may well have an active PFC design that doesn't require the selection switch (it can use either 115V or 230V).

Anyway, go through this below. Good luck.

So i got a new power supply, corsair GS700, hooked it all up, and still nothing. I've tried connecting it just to the the motherboard and it won't do anything. Got another pc and took it apart and hooked the powersupply up to that and it worked fine. Took the fans off, because i heard that if they're faulty it can stop anything from turning on, and they worked fine. So i guess i have to get a new motherboard?

Have you tried running the computer with the motherboard out of the case? Maybe something rattled loose during transit and you have a short somewhere on the motherboard with the case.

If it still doesn't work, it's probably the motherboard then. What are your comp specs? It might be worth just getting a new system (well, new CPU and maybe RAM) if you already have to get a new motherboard.

For that matter, how much did you pay for the GS700? Corsair GS is usually a little overpriced compared to its real value, not to mention that you don't need a 700W supply unless you're running two mid-high-end graphics cards.

Power supply likely died. I have seen instances where I left my comp in my card and it was really cold. It wouldnt turn on for 40+ minutes till it warmed up. Odd I know

He just said a few posts up that he got a new PSU and it didn't solve the issue.

Edit - With all the current info, it sounds like a mobo issue but it's also possible, since this only happened after moving it, something got disconnected or became loose. Quite the coincidence that you mobo (or anything really) would break in the short time and distance the computer was moved.

Thanks Charger, just being lazy. It can only be so many thing. IMO Likely an issue with the connection of the on off switch. Is the 4 pin 95w plugged in to the mobo ? Take a picture and how us !

No worries, just trying to help.

Another possibility is that the mobo isnt grounded properly or one of the plastic connectors inside the plug has become misaligned and isnt getting good contact to the pin

As far as I can tell it looks plugged in
and what i've heard on other forums is that gateway tends to have bad power sources and when they go they can take the motherboard with them, so it seems like i have to pick up a new one
any suggestions?
this is my computer

When the power supply takes the mobo its normally pretty obvious. Since the computer would need to be running. try to unplug everything but the motherboard and double check the power switch connection. See if you can atleast get it to post, or maybe get a power indicator light on.

Have you tried to move the machine back to the same power outlet ? Does the power supply cable have a ground plug? Is the outlet bad ? I know some of these seems obvious but if you havnt checked each atleast 20 times you havent done your part. Either way check it again.

What else changed ? If you cant get the case fans powered up It and have bought a new PS its an issue with turning it on, do you have a manual to the machine ? or to the motherboard?

The main power plug on the motherboard, the long whiteone. Smell that portion of the board, does it smell like smoke or is their any type of black marks ? If not even its its damaged you should be able to get a case fan working.

there's no burn marks or any indication of it breaking, i've checked all the parts on a seperate pc and its plugged into a really good surge protector. I've checked the outlet and everything a million times. And there are no lights or anything working, making me think that its the motherboard that died on me.

have you swaped out power cable even? sounds strange I know but i have seen it work.

are you familiar with where the power plug connecter plugs in to the mother board ? If there is something gateway skimps on. the power button is right up there.

You still are dodging the question as to where the power button plugs in to the motherboard. I am assuming that means your not familiar.

FInd these plugs inside the machine and lets talk about where they go and where they are connected. In a prior post you said you plugged the PS in to another machine and it worked.
Thats a good sign,

Plugs!

For the record, your computer needs no more than 400W in the worst-case scenario, largely because the GTX 465 is hugely power inefficient (GTX 465 alone can get up to almost 250W). I wouldn't use a Corsair CX430 because its 12V capacity is only 336W, but most decent 500W units would have been enough easily.

It seems like a shame, but I guess you'll have to try another motherboard. i7-860 isn't worth upgrading, for sure.

Did you try taking the system out of the case, as I suggested?

Honestly I dont know where you getting your numbers,

260w for the video card under full load,
125w for the Cpu,
70w for the board,

we havnt counted ram, usb devices, harddrives, optical drives.

A minimum of 600 watts is where you want to be considering the degredation of the transitors can be in excess of 30% in the first year alone..

an issue with how the power button is connected to the motherboard, or a grounding issue. It seems pretty straight forward if you ask me.

I found the plugs and they look plugged in
and there are no hanging cords that arn't plugged in anywhere and i've made sure they're all in good so ya, should be good

the psu that came with the computer had a very low 12V capacity, when i went to pick up a new one the guy was suprised my computer lasted as long as it did
and ill try taking teh system out of the case now to see how it goes
but i don't have a lot of faith in it working
but ive got to do it to put a new one in anyways so might as well try
