Computer shuts down automatically after few minutes

[dragonece]

Hi,

I purchased a new system of below configurations a year ago. It was working perfectly till few months ago. System shuts down automatically and doesn't turn on. I need to switch off the electrical supply wait for few seconds and then need to turn it on for switching on the sytesm. I have not overclocked the cpu. When i checked with my dealer. He advised to go for replacement. Replacement done for my motherboard and cpu but issue still remains the same. I am using stock cooler. Please help me out.

Configurations:
CPU: FX8350
Ram: transcend JM1600KLH-8G
Motherboard: GA-78LMT-USB3

Idle temperature is around 28c - 45celsius.

Thanks in advance for any suggestions.

What's your complete config? Psu?

I would guess the problem is your PSU failing.

When the computer shuts down, does it become a blue screen or instant "off"? What does Windows event log say, is there some clues there?

I had a similar problem two weeks ago. Changing PSU fixed it

maybe your PSU need to change... or maybe your VCARD

Is it full of dust??
Have you checked?

Dust implies overheating. His idle temps at 45C are kind of high, but not high enough to cause a shutdown. It would be helpful if he'd monitor temps on a test run to see how hot it gets before shutdown. It'd also help if OP would try running a stress test immediately after boot to see if that'll provoke a faster shutdown (again monitoring for temps).

Regardless, replacement implies a completely new HSF remount, which would eliminate dust in the short term.

But yeah sounds more like a PSU issue from where I'm sitting.

I agree its probably the PSU, but test video as well. gb
