Hi all,

Just a series a lot of frustrations today, i'll try to spell out the situation best i can.

Specs
i5 4690k was OC to 4.3 recently
asus z97-e mobo
corsair 850w psu
ati radeon 5870 gpu

___

1) recently OC the cpu to 4.3, ran stable for a couple weeks. GPU was getting hot yesterday so i manually turned up the fan via ATI catalyst. After turning up the fan, i noticed noises from the GPU fan.

2) computer shuts off unexpectedly about 2 hours after GPU noises

3) restarted computer - monitors show no displays

4) plugged 1 monitor into mobo VGA to display the desktop. disabled GPu device, reabled and added updated drivers

5) Eventually I got the computer working as per normal again, however I noticed the gPU temps rising above 100C and the fan would read 100% but i can still hear the fan pulsing intermittently (at this point I figure the GPU fan is the problem)

6) Tried last attempt to save GPU, took apart from mobo and case, compressed air the dust from the gpu. reinstalled into computer

7) turn computer on, experiencing on/off problem

8) removed GPU again from computer, ran computer without GPU installed, still on/off problem. Fan, mobo lights, leds all come on while the computer is starting to boot. checked connections all secure, everything is plugged in as per normal. The computer will boot up for 2-3 seconds, then turn off, and continue to repeat the cycle. Never fully boots.

_________

Yet to try - mobo battery trick, testing PSU

_______


any ideas on this ? At this point i'm pretty certain the GPU fan is no longer working properly because I tinkered with the manual fan settings ? (this feels really stupid since they are the factory cataylst program....).
i'm not the most mechanically inclined so i'm short the tools for any extensive troubleshooting.
Very frustrating just running into problem after problem, any help would be appreciated thanks.
 


It wasn't able to boot back up to bios so I cannot set anything back to stock.



 
Was able to fix the issue.

I believe I unseated one of the Ram sticks while moving the GPU out the first time.

I just removed the Ram sticks and put them in individually to test each stick, and the computer booted up normally. Now I am running off the internal graphics and waiting for a new GPU.
