====== System Interrupt ======
My computer got so slow that the mouse was slow and jerky and I had to reboot. System interrupts was at about 30% CPU time. My PC is now with 5 days uptime and the bug seems to have disappeared. The following solution seems to solve the issue :

* 1. Right-click on the speaker icon
  * 2. Select playback devices
  * 3. Click on the speaker properties
  * 4. Go to the enhancements Tab
  * 5. Click Disable All Sound Effects
  * 6. Click OK. You're done!

The sound enhancements seem for some reason to cause the problem even when not used. So disable them following the procedure above. Good luck!

Kill High Disk IO Processes
System interrupts can be caused by high disk IO processes. So, while we’re at it, we should probably take a closer look at the resource monitor and monitor all processes with high disk IO (read, write queries).

Ok, so open up the Resource monitor as mentioned in the link above and go to the tab Disk

Check Processes With Disk Activity

On the tab you will get a list of processes with disk activity. Inspect all of them. In my case I had a .exe file called ppped.exe that I wanted to inspect a little closer. As it turns out this processes belonged to my APC monitoring tool and was constantly writing the APC watt values to an XML file. What an annoyance. It’s cool if you want to log stuff like that, but if it’s slowing down my disk then I have to kill it.

Disable your wifi card in Device Manager and uninstall its drivers. Then let Windows install the device automatically. Should fix it :)
