GPU or PSU Problem?

[Jay4275]

Hi, last week I was playing Far Cry 4 on a GTX 760 when my monitor lost connection, and my computer then restarted itself, when it booted I heard the Skype noise, but I had no display so had to hold the power button and power off, when I powered on, the GPU fans were spinning 100% and still had no display. I then left it a while, powered on and it returned back to normal.

Since then I reseated the card, checked all connections and dusted it, Today the same thing happened on Project Cars twice, then it just wouldn't display at all and the fans wouldn't turn down. It would always happen a few minutes into a game, and only while on a game. Desktop was fine.

Ive now taken my GPU out and I'm using the on-board HDMI and as of right now is all OK. Now I don't mind replacing my GPU as I was looking to upgrade, but I'm worried my PSU may be the culprit, and may have killed my card and any new card I put in might have the same fate. The PSU is an XFX 850W Black Edition which I know is plenty for that card.

Having tried the GPU again a little later in a different PCI slot same thing, fan spinning 100% on GPU, no display but can hear all the startup noises.

I would like to know whether its just the GPU that's died, or perhaps my PSU is dying as it can't supply enough power when needed, as like I said it only happens in game, which may have also killed my GPU. If anyone could shed some light on what might be wrong that would be great, thanks.

It looks like your card might be overheating or faulty

Thanks for the reply, its looks like it, but you don't think there's any chance my PSU is faulty? it would be safe to put a new GPU in?

I find it a bit suspect that the monitor connection drops first before the whole computer turns off. When my PSU was faulty, the whole computer would reset at once.

I assume you have elimited temps from the equation? If not, check for that first, use MSI afterburner and run a test using benchmarking software to see what kind of temps it reads as the benchmark runs.

After that, if you have any other graphics card, try swapping it out.

Next option would be to try a different PCI slot for the card. After that, if you have any other graphics card, try swapping it out.

Yeh, the monitor lost connection followed by the game sound stalling, then the whole system restarted a few seconds later. So you would say its the GPU then?

As I say I've been looking to upgrade so if its only the GPU that's fine even though costly.

I've tried the card in another slot on the same board but nothing, I can't get the card to display, so I cant get any temps AFAIK? Don't have another card to test unfortunately.

Both times this happened the computer has just been started up in the morning after a fairly long period of gaming the nights before, card temp would hover around 80 degrees in Far Cry 4 the time I checked in GPU-Z but I didn't check as often as I should.

If you don't have a spare GPU to swap, then before I go recommending RMAing your current one or buying a new one, you should try to eliminate any other possibilities.

Check your RAM, try 1 stick at a time and run Memtest, see if this keeps picks up any problems, and also try gaming with it and see if it does the same thing.
Check your HDD/SSD, using something like crystaldisk to see if there are any problems.
Make sure your graphics drivers are up to date, if they are, are you aware of any driver updates that might have caused a problem. Have you tried rolling back to old ones?

It could also be something as simple as the cables connecting the PSU to the graphics card being loose or faulty. Have you got a spare to replace it if you have any spares that came with your PSU, or have you tried taking them out and putting them in again, making sure you can't just pull them out again without pressing down on the tab

Try these things in the order that suits you, I suggest the cables first as the easiest option.

Check the GPU temps when your in game too.
