Need Your Help with High Latency and Dpc issues ..

Recently I Downloaded a New Game ( Duke Nukem Forever ) in the beginning I noticed that the audio was popping and cracking i googled it and som ppl advised me to use DPC Latency Checker the Latency was getting very high while playing games or watching videos the sound was popping every time i place my mouse on a hyperlink (In my facebook account) or any other hyperlinks on the web
the latency was also getting high when i minimize a window . i tried disabling my drivers , i found that when i disabled my graphics driver there was no cracking sound
Using Latency Mon (another software ) i found that the highest dpc is caused by My Nividia driver
and dxgkrnl.sys (direct x thing)
i also tried updating my drivers and reinstalling but no good didn't help at all

My specs :
MB :ASRock G31M-S
Memory : 2 GB DDR2 Memory
Graphics : Nividia GeForce 9500 GT 1GB
Sound : VIA High Definition Audio
Processor : Intel Dual Core
am using Windows 7 Ultimate 32 bit

NOTE :i Never Had any problems like this before and i played a lot of game on this

The Slightest Help will be appreciated

Best Regards :thumbs_up:
