Yes
I wonder if anyone could help. I bought a GTX560ti 448 off ebay to replace my GTX260
I put it in and the computer shutdown on stress
Although I had a 700watt power supply it was a cheap make so I bought a corsair one that can happily run sli.
I also removed a raid enclosure which was running 4 hard drives to reduce the power consumption.

The card ran ok at first but then started to shut down the machine again to the piont that it now shuts down after a few minutes even when Im not running anything.

the seller is saying its my computer. but I dont see how it would run a gtx260 fine but not handle this

computer spec
asus rampage gene III
i7 950
12gb ram
corsair power supply
ssd drive boot
2 other hard drives

nothing else other than a few devices connected via usb and 2 extra fans inside the machine.

I am going to do a format and reinstall but I cant do that for another week as im getting to the end of a contract and have things installed that are a pain to set back up.

anyone any thoughts?
 
shuts down or reboots?

if its shutting down is the cooling in your case sufficient? from what i remember the high end nvidia kit kicks out a lot of heat.

check your event log also.
 
shuts down.
The gtx560 runs cooler than the gtx260.
I dont have the side on the cases so lots of air flow and I have large (12cm I think) fan just outside the case pointing at it.

It did it this morning and the computer hadnt been on 5 mins and hadnt run anything for it to warm up. I could get my head around it more if it did it jsut during full on stress like playing battlefield 3 but just in windows with nothing else running?

The only thing that has changed is that kaspersky license ran out this week but that shouldnt cause the problem.
 
I'd check to see if you have knocked the cpu cooler or pulled any of the power cables loose?

when you say shuts down I assume you mean it's just a sudden loss of power? if so will it power back on immediately or do you have to wait?
 
the ti is the overclocked version isnt it? did the previous owner change any of the clocks?

from what im reading the 560ti needs 38a on the 12v line, do you know if the corsair meets this?
 
My bro had one of those power supplies and it was noisy and generally not that good so I would not rule that out as being the culprit even though yes it should handle everything you have

have you tried putting the 260 back in to see if it still does it?
 
260 is back in and not a single shutdown. Power supply silent. Computer hasn't been this quiet so I don't think that's a problem. The seller is saying something about a custom bios now. I have emailed card manufacturer
 
All is pointing to a faulty card.

Just check that the part you plug the power supply into is all intact and well and that it it connected properly. Also make sure the fan is moving properly and nothing is interfering with it.

Could well have been damaged in transit.
You didn't touch the card when it was powered on or anything like that I assume?

Must agree, think you wasted a wee bit money on a new power supply too.
 
Im thinking the card is faulty but the seller wont even entertain the idea. The power supply did seem to help at first. before the machine shut down when I ran battlefield, with the new power supply it didnt. but then a few days later the problem started and it got worse to the point where I had to take the card out.
 
I have emailed him to say I will be if I dont here of Palit as I have emailed them as he has requested. I only have a few days before I cant open a dispute anymore so this time tomorrow I will be.

Looks like I will be looking for a new card, I may go ati this time for a change. I need a display port connector and Ati seem to have them more than nvidia
 
opened a case today as I can tell the seller is going to make this difficult. He is saying that as the computer boots up with the card in that shows that the card is working fine.
I dont see how he can say that when Im using this computer fine now with no shut down running the GTX260. if I put the GTX560 in my machine shuts down after a short while. has to be a faulty card.
 
That seller either has no idea what he is talking about or he just wants to get out of refunding you, so you made the right decision to open the case now. Hopefully he'll offer a refund now or eBay will sort it out for you :thumbs:
 
Daft question maybe but have you plugged in the extra power lead to the gfx card?

I don't think it would have worked at all without everything plugged in?
 
Probably not no.
 
Everything is plugged in. Im going to try one last thing which I was planning to do anyway Strip machine make sure everything is in properly. And then with a full windows reinstall that should eliminate both the hardware and the software. might not get around to it for a few days tho but will be done soon.
 
Have you made any observation as to whether or not the fan on the 560ti is stopping or even sticking whilst switched on?
 
A couple of thoughts. If you do not have any monitoring software try downloading something like PC Wizard or SpeedFan. These won't help if there is a fault within the card but may show if the card overheating.

Do you have another PC you could try it in, or a mate you could get to try out?

This helped to solve a problem for one of my mates. He bought a new card and his PC would not boot. I tried it in mine and all was OK. Saved him hassling the shop, but if the card you bought could be shown to produce the same result in two machines you'd have an even stronger case.

thanks for everyones help and advice, I didnt have another machine to test in, all fans on everything spinning fine. Currently done a fresh reinstall, set everything back to default in bios then changed only the things I knew to be relevant, so as the drive types as oddly enough I read that can cause a problem.
Installed latest drivers, Ive already done a bios update, I made sure the card wasnt overclocked
oh and before reinstall I removed all ram and put them back in, I checked all the power cables to everything.
So far no crash when running kombuster tests.
So it seems it may not be a hardware fault, will see later when i stick battlefield on and run that on full.
Computers do my head in sometimes, something so simple has taken me an age to deal with.
if it does continue to function I wont know what the exact fault was as I didnt have time to test one thing at a time to see what fixed it but as long as it stays stable thats all that matters
 
Not sure how much this helps but I've got that card and am running it fine on a PSU that came with a Dell XPS 420 which is the 425W one (not the 375W standard one). I think the manufacturer of the Dell PSUs are supposed to be quite good quality but it's still only 425W. There's 8GB Ram, x3 Hard Drives and all the USB slots being used.

Good to hear it's working now.
