hi,
The graphic card which i use for my laptop is of the gtx 480,i have upgraded my last card due to the heating problem,but the new graphic card has created the problem of high dpc latency, when i try to srcoll in various browsers then the latency becomes high, the latency is mostly around 50.000us,the high latency problem is created when i play the games and even creates some sound.

The problem of high DPC latency for your machine after the upgrade of gtx 480,but this kind of problems were mostly faced by the video cards due to the drivers of the nvidea,this issue is just due to the conflict between the hardware and driver conflict.The Conflict might be between motherboard and audio drivers.

This problem is on windows vista,W7 seems to use the same driver as Vista as well,the high DPC latency spikes cause a lot of interference in the smooth playback and recording of audio,you may use it by keeping the driver of,W7 is a bit better with DPC latency than Vista but still for a lot of people unusable with this driver on.

The similar kind of problem is faced by me on my gtx 460,this card mostly affects for the games like starcraft 2,here my machine gets crashed and even creates some kind of problem, so please any one let me know the actual problem behind, so that i may inatall the required drivers for it.
