Computer shut down and won't start

[ktorrresxiii]

Hi all.

After running Heaven 4.0 benchmark I reached the score screen and then my PC shut off. Was following the lifehacker gpu overclock guide.

Now when I press the power button the case fans (and LEDs), PSU fan, gpu fans, and CPU fan turn on for half a second then shut off. I then have to turn off and on the PSU switch for it to do that again, or else no response from pressing the power button.

All help is appreciated.
Motherboard: MSI Z77A-G43
RAM: G.Skill RipjawsX 16gb (2x8gb) 1866Mhz
CPU: Intel i5 3570K
PSU: Corsair TX650M
GPU: Asus Strix GTX 970

Sounds like power supply issue..

clear the cmos, leave it for a little while then try again. it might just be too hot and is not powering up in order to prevent damage to the hardware.

like Burpo I think your power supply has failed. Replace it and hopefully it failing didnt damage any other part of the system.

When considering replacing the power supply should I be looking for more watts?

I would test your current PSU first, if you can. I still feel like your problem is heat/OC related. I would consider that before you go shopping for a new power supply.

More wattage isn't necessarily going to help you unless you can determine how much power your machine is drawing under full load. I don't expect that it's maxing out that power supply, though.

you can use a paper clip to test the psu https://www.youtube.com/watch?v=ixcWCrYpw3Y

If the psu is good, you can pull the vid card, hook your monitor to the on-board, and try to boot from your i5 gpu. After clearing the cmos as suggested above. If it boots with the card removed either the card or slot are probably hosed. You have a 4x slot you can try to use the card in at that point to help narrow it down, but slot would be more likely.

Hi just saw what you've said, I have not tried it yet however I pulled out my GPU and hooked up my previous GPU and the computer was able to start. Does this mean my new GPU is dead?

What was your old GPU?
It's possible your power supply is failing & not supplying the new GPU with enough juice.

Old GPU is Asus GTX 650 Ti

GTX 650 Ti, 110 watts at load..

GTX 970 Subjective obtained GPU power consumption = ~ 168 Watts.

That's a pretty hefty increased load on an old PS.. AND you were pushing it..

 

[ktorrresxiii]

Going to attempt to hook up GTX 970 on a friends PC with 1000W PSU.

After installing GTX 970 in my friends PC, his PC did not boot up as well.
