As of recently I have the problem that at random points the PC seems to shut itself down, I hear a click as if  it would go to sleep mode but the power button stays on aswell as the fans and other components. The problem also occurs when I try to shutdown the computer manually, it hear the click, screen goes black but all the insides stay powered. Last time i could also hear a buzzing noise through my headphones, probably the audio signal turned to shreds.

I run Windows 7 on:

i7-860

MSI GTX 970
Antex-HCG 750 Watts
Probably some Intel H58 motherboard.
6GB of DDR3 RAM

 

It's an improved Acer Aspire M7811.

I am however on the lookout for a new computer, so the only thing that bothers me is wether or not the issue could be caused by my GPU or PSU since those components I plan to move to my new system.

Start with these free diagnostics:  http://www.carrona.org/hwdiag.html

From your description I suspect an issue with your video card.

So, please do this also:

- open Event Viewer (run eventvwr.msc from the "Run" dialog)
- expand the Custom Views category (left click on the > next to the words "Custom Views")
- right click on Administrative Events
- select "Save all Events in Custom View as..."
- save the file as Admin.evtx
- zip up the file (right click on it, select "Send to", select "Compressed (zipped) folder")
- upload it with your next post (if it's too big, then upload it to a free file-hosting service and post a link here).

FYI - If we're looking for Event ID 41 errors (unexplained shutdowns), there's more info on that here:  http://support.microsoft.com/kb/2028504

While waiting for a reply, please monitor your temps with this free utility:  http://www.cpuid.com/softwares/hwmonitor.html

Alright I did try to turn my PC on but within minutes it shut down again, I am getting worried about my GPU so I actually replaced it with my older one, I am now in the system. However I do want to mention that I had the impression that my pcie power connector was not thightly connected to the GPU, especially the 2 pins at the side of the 8 pin connector were appearing to be a bit loose, however the PC did start, and the GPU light always remained on so I do not know of this could be the causation of the problem. I have attached the Eventlog and will reseat the new graphic card with extra causion concerning the power pins, and will run the diagnostics later when I have a bit more time at hand. A broken GPU would really devastate me, as it is only around a month old.

Admin log shows a consistent controller error with your CD drive.

Please disconnect the CD drive from the motherboard and the power - then run the system to see if the CD controller errors go away (a day should be sufficient).

 

But, as the old video card would shut down - and the new one doesn't - the problem is most likely with the old video card.

If it's only a month old it may still be under warranty.  Check with the place that you bought it from.  If they don't warrant it, then check with the company that manufactured it.

I reseated the video card, this time I heard clicks when applying the power cables, something I don't think I did last time. I put the computer on for five hours with Shadow of Mordor running as to put some stress on the GPU. When I returned I did some usual stuff, browsing, playing some League of Legends, checking mail - give or take 4 hours - then I let youtube play for the remainder of the night all in all the computer was operational for 15 hours or so and did not shut down. Perhaps it could be a faulty seated video card that caused the problems? I had no problems shutting down the computer in the morning.

It's very possible that that was the problem, I'm glad that it was a relatively easy fix.  Thanks for letting us know!
