Something just blew up in my PC...

Hi guys,

Had my new Z170 rig with a 980ti running now since the Z170 launched at the start of August. I had three 24" dell monitors hooked up to the 980ti and it has been running fine since August.

Yesterday I replaced one of the dell monitors with a new Asus PG279Q 1440p monitor.

All was running fine for about 3 hours and then on one of the dell monitors I started to get some green lines going across the screen when I moved my mouse. I tried rebooting but it didn't stop. I decided to try out 1440p GTA5 on the Asus mmonitor to test it out. I turned off the other two dell monitors and was just playing on the single ASUS. GTA5 looked great but after about 20 mins...

BANG...something blew...

Everything turned off, and it knocked all the sockets in the house out including the RCD in the fuse box.

I turned off the two plugs in the office which my 2 surge protectors are plugged in to, into which all my PC stuff is plugged in to. Reset the fuse box down stairs and gradually started turning stuff back on in the office to see which wouldn't work.

All my other stuff, speakers, monitors NAS etc all turned on. I unplugged all the cables from the back of the PC except for the PSU power cable (A Silverstone ST1000, about 8 years old now). I unplugged the power cables from my 980ti just to see if the PC might boot. The little green light on the PSU came on when I switched the little switch on the back of it to the 'on' position again which I didn't know if it would if it was the PSU which had blown, and then I turned on the PC. My LED strips flashed for a milli-second and that was it.

So its either the mobo or the PSU. I have a brand new Corsair AX1200i sitting here which was an RMA replacement from about a month ago I hadn't got round to fitting yet, but I don't want to plug that into the mobo if the mobo is dead. I have one of those jumpers to test if the silverstone is dead but I don't want to blow the sockets again if its buggered.

What would you do? Plug the new PSU into the rig and see what happens? Or use the jumper on the one thats already in there now to see if it actually dead?

When it blew it was a loud bang, my mrs heard it from downstairs over the TV before it got knocked out too so I'm guessing its something quite substantial which has blown. Just had a look at the mobo and the power supply and I can see anything obvious...

99.9% sure it's the power supply. Don't bother testing it, just replace it with your Corsair. If you're lucky the power supply did not take out any of your other stuff when it died.
 
First I would disconnect everything from the motherboard and do a visual check on all caps. If all is good I would then get a psu tester which are relatively cheap compared to the value of your psus. Test the psu if all is fine then test the board with only ram and cpu to see if it posts.
 
Shouldn't be. The 980ti is a capable card although it would be drawing more power your psu should be providing clean power. It certainly won't hurt trying a new psu first though
 
I unplugged the power cables from my 980ti
dont try and restart the pc with the 980 plugged in it may short through the pci slot, removing the power cables isn't enough

LOL, its the 980i! Just turned it on and a little 'click' and some smoke from the 980i! Turned it straight off! Maybe my little mishap did more than I thought a while back!

Can't see exactly where the smoke came from becasue I have a block and a back plate on it but I'll order a new one now and rip this one apart to see if I can see any damage!!

Did the smoke come from the Card or the Mobo? Definitely sure?
 
Nearly 100% sure from the card, it came right from the back part which sits out just past the mobo. Once its out (after draining the loop) I will try booting it again and look for damage on the card.
 
As one who is planning on buying a 980 Ti card early next year I take it you done something at an earlier date (Mishap) to fry the card? I should expect an OC built PC with 980ti to not go bang on me is what I’m saying.

Sitting with an eleven year old PC that I take to bits every year just to clean and it’s lasted me since Nov 2004. Everything has moved on that much I’d rather a professional at OC built my next rig. Although I did stop playing BF2 PR as it was just killing it with blue screen of death after an hour or so. So just stopped playing games on it. I just took it my old GFX card was showing its age.

Anyway rambling good luck getting your system back up as it reads as a sore one. Although I imagine warranty will cover it all.
 
Yeah I linked to the thread above. There was a stripped screw when I got it but I had already removed other screws and more importantly the one with the warrenty seal on it. I knocked a little bit next to the screw which moved. I thought I had got away with it but obviously not. I have been building PC's for about 15 years now an watercooling for the last 10, I have never had anything go bang on me and I imagine it was my fault this time, evenn worse is that the 980ti have gone up in price since I bought in August!!
 
Maybe a temp card till pascal comes out? or even a temp card till you get get the 980ti repaired. If at all possible.
 
Well the PC boots without the 980ti in again, and looking at the 980ti there is one of the small black squares in the region of where the smoke came from that has a slight 'bulge' to it and an area which is slightly 'shiny' unlike the rest of them so I can only assume that part has let go. I will post a pic of it tomorrow when I hopefully get my main PC back together with the arrival on a new 980ti. I will try that first without the water block installed just to make sure everything else is ok.

Expensive lesson learned!
