Solved Computer whines then shuts down, determined to be Gpu or PSU

September 13, 2016 at 16:48:29
Specs: Windows 10, i5-6600k/ Hype X fury 2133 DDR4

Edit: Its definitely the PSU, thing is I've only had it for 2 months and I am currently running only the bare minimum for keeping a PC running. I am not even using my GPU, and its whines, also it was a replacement already for another one. so I think the problem was that I bought an EVGA power supply
I have had this problem for a while, but not until recently has it really bothered me. My computer shuts down not long after running, well anything for more then 5-10 minutes. The PSU is under too much voltage input, so it cannot output enough to power the PC. Or at least that is a theory. Although I don't believe the second one since I've had this whining issue even after replacing the PSU with the same model. Also the issue started before I installed two extra hard drives on my PC to copy files from.

✔ Best Answer
Your explanation is confusing with various mixed up symptoms and comments These bits make no sense:
"The PSU is under too much voltage input, so it cannot output enough to power the PC". What do you mean?

" I don't believe the second one". The second what?

Best set out your issues in a clearer way, one by one.

If there is a whining noise from the PSU it needs replacing. It is probably the fan bearings and although it might be possible to look inside and lubricate the bearing (usually under a sticker) you have to be careful. Components within the PSU can remain charged, also it is very easy to break leads off when dismantling.

Always pop back and let us know the outcome - thanks

You didn't provide any info about the PSU. We know the brand but not the model number or wattage. We also don't know which graphics card you're trying to run with it.

I suspect the CPU is overheating. The Tcase temp for the i5-6600K is only 64C. Did you check the temperature?

The whining is probably a fan...but which one?

The only way I can get into it would be by voiding the warranty, so I'll probably RMA it back to amazon, It'll cost me a restocking fee, but I think it would be worth it besides the fact that I have to order another PSU, this time one that will hopefully hold out for longer than this PSU. Thanks for the suggestion and I'll keep it in mind in the future for any other similar psu problems I find. Also the more I look into it the more people dislike EVGA PSU's, the more reason I find to return it.

Once again, no model number or wattage. Providing that info might help someone else in the future.

Did you determine that the PSU cooling fan is bad? There are generally numerous fans in a PC - CPU, GPU, chipset, PSU, case, etc. One way to check is to use a length of tubing as a make-shift stethoscope. Hold one end to your ear & move the other end from fan to fan until you identify the noise maker.
