Computer turned off, only runs about up to a minute before turning off

[Jesse_103]

Yesterday my computer turned off while in the middle of playing games, and when i tried turning it back on, it would refuse until the fourth or fifth attempt to turn on, and even then it would only stay a minute up before it'd just shutdown.
I looked around here and other sites and from what i could tell, it looked to be the PSU, my PSU was a roswell gold 750W, I went and bought a cheap EVGA 650W (not certified from what i can tell?) and put it in there just to see if that was the problem.
My Computer ended up working after that for about an entire day, i was able to play games and watch videos fine until the next morning. I'm back to step one, my computer turns on (now on the first try) and works for about a minute before shutting down.
Everything is working inside from what i can tell, lights and fans all on and moving.

Heres my specs:

I do have a gold certified 1000W PSU on the way, i'm thinking maybe the PSU i just bought is weak because it had fixed the issue for a day.

So far what i've tried:
- replaced my PSU with a cheap one (fixed it for a day)
- took out ONE of my three 4gb ram sticks (let me run my computer for an extra minute before shutting down and letting me get past a minute again)

Please help, sorry this is so long, just trying to be thorough

the gemini has 500-1600 rpm and my current one has 600-2000rpm

What I was thinking about what is your cpu fan running at now.

Hey so just a final update, i installed the Gemini cooler into my rig and did a stress test on the CPU again,

i ran the test for 30 minutes and it reached a max temp of 75 C

at idle the temps for my CPU stay around 30-40

i've also yet to install the 2 fans that arrive tomorrow

these numbers look good correct?
Thank you so much for all the help and advice Luminez, i truly am very grateful!!

75 celcius is a tad high.

Do a second update when you add the fans, and try a gaming test instead of a stress test, since when you use your computer like you normaly do: Browse the web, watch youtube, games, etc you would not use the cpu at 100%
Play one of your newest and most cpu heavy game that you have. Keep HWMonitor running in the background, play for 30 minutes and quit. Look now at maximum temps and post them here.
