Hello

Intermittently, my graphic card slow down and the mouse move with a slower pace than normal

This system as 4 monitors screen. Two of them are driven with USB graphic card, the others two are driven with my graphic card, Asus EAH4870 DG 1G. This is the one that as slowing down

I can drag the windows that is displayed by the grapfic card over the screen driven by the USB card, all is smooth

Please properly fill in all system specs in the box below your post. What we are most interested in is Processor(q6600),
Motherboard, memory(RAM) GPU("grafic" card(both PCI-E and usb), and what resolution you are running the 4 monitors at.

Thanks,

James

Hello James

I will test that later as I'm working with the system and just can't close application

As mentioned, this is an intermittent problem. When it occur, USB adapter is still smooth will the screen driven by the card is choppy

Question: What if my PSU is not driving enough current for the video card.

Will the symptom apparent to that or the card will not function at all?

One more question, when the choppiness occurs, are you doing things that are more graphically intensive on the GPU powered monitors?

No

I'm displaying trading charts. It is the same during the whole day. When it occur, I'm not doing anything differently.

I taught that it could be a overheating problem ( card is not overclocked) so I opend my case and placed the pc tour on the side to make sure that the eat is getting out of the PC. Same problem
