Computer shuts down 3-5 secs after hitting the power-on button

It all started with me just playing a game, when everything suddenly froze, the lights in my keyboard and mouse shut off and I all I could do was sit there. I then decided it was probably just some driver issue and proceeded to hit the power button so as to turn off my PC to reboot it. The PC turned off and started up again and just as I thought it was all fixed, it just suddenly shut down again, and it kept repeating that turn on and shut off pattern until I decided to cut the power.

I then searched around the internet for some help, and found a thread with a guy who fixed a similar issue, by removing the CMOS battery and putting it back in, so I tried that. It worked for a little bit, I was able to start up my computer and use it normally, until about 10 min later, when it froze again, and when I wanted to restart it, it just kept repeating the same pattern as before, turn on, shut off etc...

So now I have no idea what to do, and I was hoping that someone in here might be able to help me.

Thank you in advance.

Sounds like it's overheating. Are the fans all spinning? (I'm guessing that pulling the CMOS battery didn't actually help, but the powered-off time let it cool off a little.) If you open the side of the case and point a desk fan in does it run a little longer?

How old is the computer? If it's more than 5 years old it's probably a good idea to replace the thermal compound. Check for any damaged components on the motherboard and graphics card. Specifically look for any leaking capacitors.

could be overheating or ram issue. If you are using a liquid cooler for your PC, try replacing the thermal paste, If not try pressing on your pump while its on to make sure you are getting good contact. If it keeps turning off your pump is bad.

It pretty much fixed itself, I removed all non-essential hardware and started plugging it in one by one to see if any of my components were damaged, but without luck. Then I removed the CMOS battery and placed it back in a couple of times and then it suddenly worked, haven't had any issues since.
