PSU making noise before crash

[moonnecter]

Hi,

I made a post a few days ago about my PC not turning on at all, so I decided to take everything out and clean it, and then put it back in to the computer to try and workout what parts might not be working properly.

Well to my surprise it turned on and has been working like usual - However when I open a game such as WoW it will let me load in to the game and play for about a minute before I hear a noise in my PSU followed by a whole computer crash, with my screens going in to sleep mode and my GPU fans being on full power.
It does something similar for a game called PUBG, however instead when I get on to to the main menu, the PSU starts making a sound and the graphics start to flicker before the game crashes with a bugsplat from steam.

However I have stress tested my GPU to 85 degree, and it ran fine, I also stress tested my CPU to around 60 degrees and both ran smoothly without any issues or sounds at all.

Now I'm pretty confident it's a PSU issue, however is there anyway for me to validate this as the computer turns on and can perform tasks such as browsing and small non intensive games such as Runescape and league of legends, however when it comes under load it can't handle it.

(NOTE THAT THIS PC HAS HAD THE SAME BUILD FOR ROUGHLY 4 YEARS, WITH ONLY A GPU CHANGE IN THE LAST 2 YEARS, AND I HAD NO PROBLEMS UNTIL IT WOULDN'T TURN ON AT ALL)


GPU - Nvidia 770 4GB
CPU - Intel i5 2500k
Motherboard - Gigabyte Z77
RAM - Corsair Vengeance 8gb (2x4)
PSU - Corsair Cx 600W (non modular)
HDD - 1tb Western digital (black?)

If you're hearing a noise, tested your Ram, verified that cpu, GPU & board are fine, it's probably the PSU. It's also not the most high grade PSU and they often fail after 3-5 years.

I have replaced the powersupply which seems to have stablised the build in terms of it not crashing completely on WoW, however I'm still getting graphical glitches with flickering, which will then lead to the client minimising, then re-opening with terrible frame rate. I also touched my graphics card and it's very hot to touch.

I would assume my debunked powersupply likely caused damage to my graphics card? As again this still only happens under heavy load (gaming), however am looking for a secondary opinion on this.

Bump.

Graphics card causes flickering in games until it eventually crashes the game. However i can still run a GPU stress test for however long at 82 degree's. This seems unusual to me, because if the GPU was broken, surely it would flicker for a GPU stress test?
