    Windows 8.1 High DPS Latency issue

    Hey! Could somebody help me in a DPS Latency problem?

    The problem started when I bought my Kingston 60GB SSD and installed it with Windows 8.1 64bit OS.
    My specs:
    Gigabyte GA-MA74GMD-S2
    AMD Athlon X3 3.10GHz
    Sapphire HD5750 512MB
    Kingston 60GB SSD sata 3, Samsung 128HDD ATA
    4GB RAM

    So, I installed the OS, everything worked like a charm, after I installed my Google Chrome and clicked on a youtube HD video or a Twtich HD stream, sound and video were lagging, even my mouse lagged too. In the process manager I saw a process called System Interruptions, used around 20-40% of the CPU,while Chrome or any process didn't use above 10%.
    I looked after the problem, I read that usually drivers cause this problem, so I updated every driver I could, I even updated my bios too. It didn't solve the problem.I installed Latencymon and it said:
    ndis.sys Highest execution: 72,644579
    usbport.sys Highest execution: 66,294512
    HDAudBus.sys Highest execution: 48,778782
    dxgkernel Highest execution: 48,751122
    ataport.sys Highest execution: 48,649046

    I unplugged everything from USBs, only my mouse attached,tried to unplug my CD drive, and the other HDD, the problem stayed.
    After a few hours of searching,trying to fixing,rebooting and stuff, the problem completely disappeared for 4 days.
    Today, I ran a program called Revo Uninstaller PRO, and the problem came back immidiately. Sorry for my bad english. Could somebody help me?

    Here's my xperf log:

    Hi,

    Are you using the latest ATI driver for your VGA? Could you please provide a screenshot of running OpenHardwareMontitor to see the temperatures of your system?

    Re: Windows 8.1 High DPS Latency issue

    How long the computer was powered-on after you checked the temperatures? Additionally, what kind of devices do you have plugged into USB ports?
