GTX 480 - overheating?

Hi,

Lately I've been playing graphic intensive games and having momentary lock ups.

I install ATI Tool, to test the Nvidia card and after about 4mins I start having the momentary lock ups again.

I installed an ATI card into the pc along side the nvidia and plugged one monitor into each card.

I played my graphic intensive game! the game clients on the ATI remain fine and the one on the nvidia locks up or now I've seen the screen go blank.

I turned off the game whilst the screen was blank.. and after a short while it came back.

I bought this in February 2011 - so the most I've done is try blowing the dust out of the heatsink. What now? speak to OC about a faulty card?

cheers
 
To summarise the state of events

After a short while of playing my game client stops responding, so do the other game clients on the other monitor if they were actively doing something. If I try to do something in a game client which is still running ok, it locks up too.

After 40 seconds to a minute, it continues to work ok. This happens periodically until I eventually have to do a hard reset because it does not resume.

SO

After I blew the dust out of the graphics card, I put in another video card an ATI. The ATI powers the second monitor and the Nvidia the first.

what happens now is the nvidia display goes blank periodically, yet the game client continues to work in the back - I can see it on the ATI display that it is working.

At one point the screen went blank and did not resume, I quit the game clients with Alt-F4. The screen came back after 20 seconds.

Graphics card temps seem normal at <80C.
 
Sounds like perhaps the NV HD Audio is conflicting. Have you tried doing a clean installation of the NV GPU drivers, not selecting the NV HD Audio Drivers, and also disabling the devices in the Device Manager?

Click to expand...

I did disable all audio devices in the device manager - but I will do as you say by a selective install.

thanks!
 
Ok format reload windows.

Install intel chipset drivers and lan
install nvidia and ati graphics only drivers
install creative sound drivers
install a game which plays on both monitors

The monitor with the nvidia card goes blank during game play. When I use ctrl-alt-del, the display comes back after 10 seconds to show that screen (game clients hidden).

What more can I do?
 
i have 2 x GTX 480's in sli and tbh my cards hit 90C - 94C under load (well the top one) the bottom on e hits about 80C - 82C
 
Oh I took the ATI out to be sure, the GTX on it's own was just causing the game clients to 'stop responding' (as it was before the format reload)

hmm, I remember i had a problem in the past, with a 9800gx2.
After buying all these new things, it only turned out to be my psu.
Although it was a Corsair TX750.
I had roughly the same problem, Screen going blank (pitch black) for a certain period of time, and sometimes had screen image jumps, as if i had poor fps....

Maybe test a different PSU, if possible that is. Always worth a try.
 
I could definitely understand if it were the psu. I've just unplugged a couple of hard drives and removed a redundant cable..

Will see if that does anything, but might be tempted to get a new decent psu.
 
Well the PSU is fine with the 4870 - so on second thoughts, less likely candidate. Also both video cards, and it's still coping to keep the system alive.

The video card continues to play up in the secondary slot.
