Desktop On Off loop, Video card crashes

[MugMan]

Good day to all. Thanks for taking your time to read this.

My PC has been having the problem of a ON OFF Loop where it will simply power up, the fans will run for 1-2 Sec and then power off and turn on again into a loop. Sometimes it may turn on for about 5 Sec before turning off. Getting it to turn on is kinda like playing a lottery. Sometimes it gets out of the loop by itself. One thing I realize is that sometimes after it manages to load to the Windows Login page and I plug in my headphones, it will freeze and the PC will go back to the loop but this doesn't always happen.

Recently, the video card driver has started to stop responding at times but manages to recover itself every time it seems to occur after updating to the newer drivers.
Also, when I use Chrome for Youtube, there are times where the PC will freeze momentarily with a buzzing sound and then recover itself again with no error message or anything. When under load, E.g playing BF4 or Witcher 3, There is a tendency for it to simply freeze after maybe 2 hours of game play.

Please tell me where can I start to troubleshoot this and solve this issue. Thanks!!!

My PC SETUP if it will help:
GA-Z68X-UD3H-B3
I7-2600K
MSI GTX970 GAMING EDITION
2x4GB RAM STICK
Corsair CX750 Power Supply

Sounds like the power supply is on it's way out. If you have another unit lying around, even one that's less than sufficient in wattage overall, I'd try testing to see if the tower boots properly.

CX Series from Corsair is of poor quality. I'd never suggest using them if you're going to put the system under load. And definitely not if you're going to overclock anything.

Are there any inexpensive PSU that are reliable?

Im going to disagree with Sammy, doesnt sound like PSU to me.

Do you have any overclock currently? Try and see if it boots up using just one of the ram sticks, then switch them over and try the other one on its own.

 

[MugMan]

It isn't overclocked. Do I boot on with everything else disconnected except the Ram and CPU?

Try just removing one stick of ram initially, see if it makes any difference. If it doesnt, try the other stick on its own.

Next step would be to remain with one stick, then remove the graphics card and plug into the integrated graphics.

An update I have now is that my PC becomes sluggish all of a sudden. Like everything just lags but after awhile it gets back to being smooth but eventually it turns sluggish again. Watching the same youtube video in 1080p can be smooth or jump all over as if its a slideshow.

What is your CPU temperature showing?

 

[MugMan]

CPU temp averaging 40+. The sluggish problem is solved after I swap the power cables for the GPU.
