Pc keeps turning off after like (10-15?) minutes of use

[Shhhhh2077]

Pc turns off after around 10-15 min. Everytime I turn on my pc, it turns off after like 15 minutes of me using it and right when it turns off the LED lights flash for like 1 second. And when I try to turn it back on it doesn’t turn on except for when I take out the power cable and plug it back in. I thought the problem was the dust at first so I cleaned it at all out and still it’s doing this. I even switched the power cables, that didn’t work. Also tried out different outlets but that didn’t work too. I heard that disabling your c-state could be a fix and I did that yet it still turns off. A friend told me the power supply might be the issue so I’m going to buy a new one but I jus wanna be sure so I don’t waste money

g’day and welcome to the forums.

it does sound like a temperature thing to me.
did you also clean out the fan blades, intake and exhaust ports, heatsinks and remove the front grill and cleaned everything with a soft bristled brush.

how old is the PC, what about replacing the thermal paste on the processor?

an air-compressor or those cans of compressed air will also be helpful.

Sorry but you have post on a tech forum asking for help but have provided zero information about your computer or it`s hardware, this makes it impossible for anyone to even hazard a guess as to what is going on.

Is the computer a custom build or brand name such as Dell or HP, if a brand name, provide the model name or series number (not serial) if a custom build post the brand and model name or number for the CPU, MB, the RAM ( including the amount and speed ) add on video card if one is used and the PSU (power supply unit) providing these details will enable folk to better help you.

Thanks man. And yeah I pretty much cleaned most of it, the pcs like 4-5 years old. And I haven’t replaced the thermal paste so I’ll try that.

My bad, I didn’t even think of that. It’s a custom build I bought. CPU is a intel core i7 960 @3.20GHz 3.20. There’s 12 gb of ram and I have a GeForce 1060. The PSU’s a Corsair cx600.

Corsair cx600.

One of if not the worst PSUs that Corsair ever made, high failure rate and only recommended for entry level computers, those that only have integrated graphics as opposed to an add on video card, rated as Tier D • Recommended only for very cheap, iGPU systems here

You have not post your MB details so we can`t check to see if it has onboard video.
