Hi. i've had my pc since 2013 and haven't really upgraded much except for the graphics card a couple of months ago which was done by the company which i bought my pc from. before changing the graphics card my pc wouldn't even turn on at all, but now after having it changed it shuts down randomly even when im just on youtube and when i try to turn it back on the lights go on for a couple of seconds and shuts back off. I have to leave it alone for half an hour or so for it to go back on. so i called them up and they said it was because of my power supply. is there a way to test if this is true or not? i already did gpu and cpu benchmarks but it completed them both without shutting off.

i'm not that great with pc hardware and it's my first time here so my bad if it's obvious...:rolleyes: thanks.

My pc:
case: Cooler Master Silencio 550
power supply: 700 Watt Cooler Master voeding,
cpu: AMD Vishera FX-8350, Eight-Core,
motherboard: MSI 760GA-P43FX,
16GB DDR3 ,
SSD Samsung 840 Series 120GB, 2000 GB SataIII Hardeschijf,
Gpu: AMD Radeon HD 7970 3GB changed it to Nvidia gtx 1060 6gb
 
thanks for the reply, in the system event log everytime it has shut down it has 2 red which say: the following fatal alert was received: 70. and the second red one says: the following fatal alert was received: 80.

i havent really updated or touched the bios since i bought it mainly because i didnt want to mess something up, how do i update it?
 
Coolermaster has only few PSUs with quality parts, so that PSU is likely far over it's intended life span.

Though also that motherboard can be wearing down.
Without any VRM heatsinks that board was likely never good for such power hog "Faildozer"
 
I've had the same thing several times. It's usually a dying PSU, but once it was the motherboard VRM section on it's way out.
I only found that out after I replaced the PSU and it sorted the issue for a short period before it began again and replacing the board fixed it.

Sorry I can't tell you exactly what it is, but replacing the PSU should be the first thing you do, as it's pretty old.

ED: Last time it happened, it was a 6 year old Superflower 1200W platinum PSU that couldn't maintain 3.3v / 5v, so certainly not a cheapie.

Cheapest solution...

Clean whole PC, get rid of all the dust build up in all of the components and re-paste the CPU. The best and most thorough way to do it without risking damage if you don't have access to an air line etc. is to take it apart and then clean all of the parts and rebuild it.
 
oh wow, i just came across this as i identified my issue.

i had the same problem, finally figured it was the psu for anyone else having the same symptoms.
 
i just opened my pc while it was turned on, and discovered the problem. the cpu fan wasn't spinning at all... i think this could still be a psu problem, because not enough power is going to that fan, no? and when i push the fan with my fingers it begins spinning slightly then it stops after a a couple of seconds

That's unlikely to be a PSU issue. Most likely it's the fan. Is the fan connected correctly to the motherboard? Is it on the CPU FAN header? And the right way around? (BTDTGTTS) Fortunately these are just standard fans so easily replaceable. Which CPU cooler are you using?
