Pc shuts off after a couple minutes on desktop

[Sniper2311]

So ive been trying to figure out what wrong with my computer for a week or so. It will run on bios all day but the second it goes to desktop itll shut down after. 3 minutes at idle. Ik my cpu is way to hot its running 77 degrees Celsius. Any ideas or if need more info ask me

I would start with a cpu heatsink clean/repaste or maybe a better heatsink/fan solution on that processor. Maybe some case fans that improves flow too. Is there any overclocking been done?

What CPU and Motherboard are you using Sniper2311?

Ya its been factory overclocked to 4.3 ghz its a amd fx8370 and in using gigabyte g1 gaming motherboard. Its not solved. I hit rong button. Im goin to try to replace cpu. U think that will work

Your symptoms make me think its a CPU Cooler Interface issue. Is this your first PC Build? Can you describe in detail how you applied the thermal paste? You can try removing the overclock back to stock settings and see if that resolves the issue. Perhaps this CPU is not a good specimen for running at 4.3GHz.

No this is not my first build. And i used a spreader to put a thin coat of thermal paste over top of cpu. Ive used 2 different coolers both with same outcome shut down after 3 mins. Around 80 degrees celcius. The coolers work on my other pc

I was just thinking about the interference my case has a cpu temp sensor on the front of it i put the temp strip in-between the cooler and cpu would that cause it to do that

Yes, definitely a bad idea. There should be nothing between the CPU and CPU Cooler except a very thin layer of thermal paste.
For example even something as thick as a finger print or worse a hair on the CPU or CPU Cooler can cause it not to perform at ideal performance levels.

 

[Mark_1970]

Yes he is correct that strip should not be in there, that is the issue, the cpu can't conduct it's heat to the heatsink enough

 

[Sniper2311]

Where would that strip go

 

[JQB45]

What is the name of the manufacturer and model of the case? Does the case instructions have any advice on where to put the strip?

 

[Sniper2311]

Apevia and dont know. Lost them

If you do not know where to put it just let it hang loose in the case. It is not needed to have a fully functional PC.
