Computer says "no" [giveaway over]

The GTX alone is 400 from what I can remember (on mobile), so you could be overloading the PSU.

My last build had an issue where one essential pin on my chip was bent, and posted only once.

I also think it could be the PSU failing, can't you get a cheap-o one from a friend to test your machine?

Also, why don't you try to reset the CMOS settings taking and putting on again the motherboard battery?

Its PSU, its rules. No means no.

Just off-hand here, but I believe that you are correct in that 500w is enough for your rig. It might be on the closer side of things however. I have a 530 myself for a gtx 760. I assume you've checked that everything is seated correctly and not shorting anywhere? I had an old pc where if it was just in the right spot, It would constantly re-start due to something not seating correctly.

Try this site - It will add up all your components and tell you what you should be using.
From what you have listed here (and without knowing what drives etc you are running) you should only be pulling about 180w - a 500 should be fine, but again - the more drives/optical drives/ usb components etc you are running, the more you will need.

An interim thing to try if you like is jumping the ground wire on the main multi to the motherboard - basically, pop a paper clip into the ground wire connection (green, I think, but google it) and one of the adjacent black wires, and power it up. Shut down, remove. There are a bunch of YouTube videos on doing this. I have some reluctant PCs at work, and this often gets them up and running.

If you think it's the PSU, and if you can live without your main pc for an hour, try taking the PSU from your main and use it on your secondary pc. If it works, you know what the problem is.

computer says no... = get used to social life

good luck!

Friend of mine had same problem, pc power on and fans were working but couldn't post. In his case CPU died..

I'm fairly certain 500w is enough to power this system though.

It's more than enough, you could run it on a 250 W PSU comfortably, unless you have a lot of stuff in it. If it's the PSU that is the problem here (and it sounds like it is), don't go overboard when ordering a new one, you should probably aim lower than what you have. If you want room to expand, about 300W should be enough.

I have no idea what could cause the problem but there is one thing I am certain of, 500W is more than enough for this build.

Have you tried turn it on only with mobo?

Wish I could help but I am not that computere savvy

sorry i cant help :/ and thanks hope you will get an answer :-)

Awwwwwwwwwwwwww.. Here I thought the topic would be about the comedy Computer Says No by Little Britain x]

Bump so somebody that can help you will find the thread :)

Does the computer give you beeps after booting it? If so, refer to manual for the beep for the error codes. From the pictures. That mobo doesnt look like it has a built in LED error/post. Best to invest in a pc diagnostic card for future use. Cheap on ebay. Anyways, i would recommend to take out the video card and try booting your pc with the psu and plugging into the vga port on the motherboard. See if it boots normally. one last thing, check the voltage switch on the PSU. make sure its in your correct region:

View attached image.

Try your RAM in a different slot(h) and a different RAM. If you have two pieces, try one at a time with different slots.

Sorry to hear that you have problems, hopefully you can troubleshoot and find the part that has failed. You could try powering up the PC with the minimal setup (one stick of RAM, disconnect the GPU and use the integrated graphics, leave other components as is).

I can't say for sure if the PSU is the cause of the problem, but I think you won't lose anything if you invest on a new PSU anyway. I looked at the closer specs of your PSU from a review, and it doesn't seem to be very efficient. The reported 12V output is 36A (360W) on the label. The review results say the efficiency is between 73-81%, which is a very poor result for a modern PSU. That means you might only get anything between 250-300 watts of effective power in the combined 12V rail.

edit: I'm sorry, that was totally wrong model in the review I linked earlier. Here's a review from the same 'Elite Power' series. The results are a bit better in terms of efficiency but not remarkable.

Sounds like a PSU problem, but then again the easier way to know is to replace it to check this out.

Something that you might consider: XFX offers a 5-year warranty on it's PSUs (http://xfxforce.com/en-us/technologies/power-supplies - the bottom of the page) (if you decide to buy their product just remember to register it on their website) (also make sure that it's available where you live).

Fun fact: I bought an XFX PSU for my PC, registered it and for some reason got Dirt: Rally for free, even though I think it was supposed to only be given to people who bought their AMD GPUs.

Another thing: while it's always good to have slightly more power on your PSU than is needed, don't listen to the people who say "component X requires 400 Watts alone, so you need waaaay more than that". As noted here "The “Recommended PSU Wattage” value is for the whole system, not only for the graphics card/s." As such, your 750 Ti on this website has a recommended minimum wattage of 350 Watts, so... I think that a 500W PSU is already safe and enough.

The PSU does seem the likely culprit and 500 watt might not be quite enough when your CPU and GPU are both going at max.
