Greetings,

The other day I loaded up a game and the entire pc shut down. No bsod, or such, just a straight shutdown. Power button would not work, however the motherboard's little LED power button was still lit up. So i unplugged the psu, waited a few, plugged back in, and pressed power. For a split second the pc would start up and then die again. So I thought maybe the gpu died. I unplugged both pci-e 8pins and the pc would boot. The gpu is a Galaxy 780gtx HOF, and it continued to get the power for the glowing LED on the logo and fan power. So I shut down, tried again with the pci-e 8 pins plugged in and same problem as before.

I then proceeded to put in my old hd 4870. Powers up fine. Thought.. okay yeah the gpu is dead. However I am noticing some issues like the video driver resetting and a bsod. Often when it is playing videos on youtube or mediaplayer. I have not gamed yet as i've been working a lot and kinda unsure on the course of action.

Before i got the galaxy, this same setup had the 4870 in it, with the same psu, and i am using the same old drivers from before. Never had any of these issues. So I was thinking maybe it is the psu dying?

I do not have any instruments to read anything from the psu for voltage issues. Kinda stumped on if i should get a new psu.

The psu is a hx1000. Its been around for quite some time. Given that back then i had plans for a much beefier system and was running crossfire 4870s, i went with the hx1000.

Right now i am eyeing the corsair AX860. I run a 4670k, 4.4ghz, sdd, 16gb of ram, and had planned on 780gtx sli.



Could the psu being failing on the 12v rail, causing the galaxy to just not work period, and instability in the 4870? Would it be stupid, if i get the new psu, to try the galaxy back in it or would i risk further/potential damage to the system?

Help please!

I would suggest trying to do a clean install of the 4870 drivers. Get the latest. Also, have you tried running the 780 in another computer. That can also narrow down the problem.

I think its the PSU. Recently, I had a build where the PSU overheated and it caused the exact scenario you described. After giving it a moment to cool down and plugging it back in, it ran just fine after I gave it more air.

I do not have another system to test this in. However i have tried 12.2, 13.1, and 13.9 I believe, or the latest one. I use DDU to uninstall, reboot, CC cleaner, reboot, and reinstall. Same issue each time. I have hardware acceleration disabled in flash and firefox but it seems to get effected even with media player.

The thing is that i've blown cards before, well many years ago but I have. The card didn't do anything like artifact or freeze or any such thing. Just straight shutdown like the power literally went out to the house. I actually thought it did since it was dark when it happened. The gpu shows no burn marks anywhere on the pcb that i can see, and its white so it isn't that hard to notice.

Then, its a "it powers up for a second then just dies" like the psu is kicking off. Power button then won't respond. I have to unplug/switch the button on the back, and try again in a few minutes. The 780gtx has enough power draw maybe on boot up to kick off the psu that is dying maybe, but the 4870 is just experiencing instability once in windows and actually being used past 2D? There is absolutely no artifacting with the 4870 even when the display driver resets and a bsod. Not on boot or windows.

I am worried if i keep trying to power up the gpu, it might just kick off the psu and take some other parts with it if it finally dies when that happened.



The hx1000 came off it's 5 year warranty 3 months ago for me.
