ASUS GTX 960 shuts down entire PC

This one's going to be a long one; sorry.

PC specs:
MOBO: Gigabyte 990 FXA-UD3
CPU: AMD 8-core 3.1 GHz
COOLING: Corsair H100i 240 mm radiator for CPU
RAM: 8 gb of whatever
PSU: Corsair TX650W
GPU: ASUS GTX GeForce 960
HDD: SeaGate 1TB drive


I also bought a Hitachi 3TB drive when the problem was thought to be data corruption

Okay, so I had a Radeon HD 7870 that started to shut down my PC after a good year of having it. I thought it was time to upgrade because I had been wanting to get an Nvidia card for a while.

I bought this new GPU:
http://www.newegg.com/Product/Product.aspx?Item=N82E16814121928

I put it in the PC, then had to run but had some tech friends with me so I left it to them to install the drivers.

I got back and ran some tests to see how well it handled some games. Arma III it ran ultra at 30 fps, high at 40, etc. Every game I threw at it it did really well in my eyes.

Then, it crashed just like the first card. This would begin the month from hell. I spent a week trying to troubleshoot this issue. We ruled out ram by trading ram sticks with a friend and playing on each other's ram and my pc still crashed while his still remained on. So not ram.

I thought maybe it was HDD data corruption. Seagate HDD? Maybe. So I bought a 3TB hitachi and starting deleting a lot of files in my current 1 TB and reduced it to having 700 GB installed on it. I haven't been able to play from the Hitachi because I haven't been able to hook it up for some reason, but we don't think it's that. Can't completely rule it out, though.

Ruled out the PSU because this card requires one 6-pin connector and my old card required two so the power shouldn't be an issue... right?

Then, I thought it was the fans. I noticed this card wouldn't turn it's fans on at all before the crash. RMA'd it and got a new one. Same issues are recurring. I should note: I played with my old 7870 during the RMA process on reduced graphics settings and it didn't crash on me then.

So I'm thinking it's drivers. I downloaded DDU and got rid of all AMD drivers, then tried. Crash. Uninstalled all Nvidia drivers, reinstalled the drivers that the card came with. Crash. I've gone through so many iterations of drivers idk what to tell you at this point. I've manually installed them from Nividia, I've installed GeForce Experience and had it install them, and I've installed them from the disc that Asus sent me. Nothing works.

I have played WoW at ultra to see how it did. No crash, though I didn't stay there long; it was just an old account I used to play. Played War Thunder on max, it crashed after about 5 minutes. Played World of Tanks on high, it crashed after 15 minutes. Played Rocket League about 30 minutes ago (the game I usually test it on, the game that usually crashed it before the first title screen) and it actually played for a little bit. I almost got through one 5 minute match before it crashed on me. Currently I have the GPUTweak that asus sends with the CD.

I should note that this computer has crashed on me around 50 times in the last few weeks. When I say crash, I mean immediate shutdown, power off. A hard shutdown. No BSOD, no black screen with sound, it turns off.

I've played with temps. Nope.
I've played with fan speeds. Nope.
I've played with my other card and it does okay still with the occasional crash every 2-3 hours.
I'm at my wits' end. I've tried everything I know with this card and it just won't work.




UPDATE: vlxedits was correct, it was a PSU issue. Obtained an EVGA 750W fully modular and it's running fine.

For the record on the HDD: I "hardwired" it. This HAF XB EVO case has two drive slots for hot-swapping or whatever, but it seems that only one drive works. Simple malfunction. Fortunately it has other bays in it and I just hooked the new HDD to the PSU and SATA'd it to my mobo and it's currently being partitioned.

Thanks for the help, everyone. VLX got the solution because he was convinced it was PSU. I wasn't at first, but after everything else has failed and he said my rationale made no sense then I tried it and so far no crashes after multiple stress tests.

This morning, my PC wouldn't even turn on. At first, it powered the PC for half a second, then it died. Now, despite me making sure connections were good both in the PC and from the PSU to the power strip, it won't turn on. This makes me think the first answer, by vlxedit (spelling?), is correct.

I was unaware that Corsair didn't have a good reputation at the time of the purchase of that PSU.

Your psu reason makes no sense. The new card requiring less power than the old, so it's not an issue?

Im leaning towards it being a psu issue, since you say your computer just plain shuts off, it could be from bad voltages, plus the fact that corsair are known for making crappy units. Or, it could be a too high temps issue. Aside from that, the only thing left to troubleshoot is the motherboard ( I really dont think it's your hdd, even though you didnt fully rule it out)

Please post back with voltages and temperatures from HWMonitor

It could be several things. Failing power supply, bad stick of RAM or faulty motherboard. Unfortunately debugging these things is a bit tedious and you have to have other hardware you can test the various parts with.

Have you considered reinstalling Windows? You may have something corrupted in the registry that can't easily be tracked down or repaired. None of these things are easily. I'd probably first back up important files and reinstall the OS (if its been several years without a clean install). Then start tearing in to the hardware.

I don't claim to be all-knowing, but I would expect a card that takes less power wouldn't cause more issues. My old card takes more power and runs better than this one currently (fewer crashes). That was my logic.

I will post back with voltages and temps if I can. If you read the update, you'll find that my PC wouldn't turn on before I left for work this morning. I get off in 6 hours.

As for the HDD, memtest was fine so I don't think it's HDD even though I didn't fully rule it out as well.

I think it has to do with the case. There might be an issue with the interface, for lack of a better term. I have a Cooler Master HAF XB EVO case, which has drive slots that connect to an interface that then connects to the mobo. I still need to try to manually power and connect the new HDD to make sure that's the issue, I just haven't. I work long hours and go to school, so it's not very easy taking apart my entire case multiple times a night to diagnose one or two issues.
