Day 1. I tried to clean my board, slots, and everything inside the cpu.

Day 2. No problems. Kept on doing what I do daily. (playing League of Legends) and suddenly when I'm in the middle of a game, PC shuts off without any warning. Didn't pay any attention to it as I thought it was something random. Does not shutoff afterwards.

Day 3. Just like day 2. PC suddenly shuts off without any warning while in the middle of gameplay. Does not shutoff afterwards.

Day 4. Shutoffs got worse. PC shut down THRICE when I'm in the middle of a game.

Additional info: PC doesn't shutoff randomly when I'm just surfing the net. (facebook or youtube)
I have noticed that whenever I do something that gives a workload on my cpu, it shutoffs. When I try to convert videos to other formats, or refresh my windows experience index, that's the only time when my PC shuts off without any warning.
I tried asking friends for advice and they said that it's probably my PSU is failing and I need to replace it.

Need help badly!

Sounds like a driver issue cause you may have an older GPU. I know my oldschool GTS 250 did this when nvidia rolled out the 329+ drivers. The entire driver would constantly fail and recover or the entire PC would shut off.

Luckily I had another oldschool GTS 450 laying around swapped cards and fixed all the issues I had.

Did you update drivers recently? Try rolling those back. Does it always crash or do you get blue screens at all?

Yes actually now that you mention it, I experienced the shutoff 3x while playing in the middle of a single game AFTER I downloaded a new driver for my card on Day 4. But that doesn't cancel out the random in-game shutoff I had in day 2 and 3.

Yeah I kind of figured you can try to roll back the driver, but I doubt that will solve the issue. That's really the only option I know of or finding the old driver version you had that would run things stable, if you aren't able to do that you may want to update to a new GPU.

Maybe someone will come up with something better, but thats what I had to do to solve the crashes for my dad's old school computer.

Well that's definitely odd. I would try rolling the drivers back and re-installing them. That or like coolcole01 said could be you're PSU crapping out on you or a temprature issue causing your computer to shut itself off to prevent any damage.
