PC issues with system interrupts
ive recently been having some problems with my pc when playing DayZ with mumble open, my comp seems to be fine when i start it up and start playing, but graduly it seems to lag quite a lot and the sound sort of tears. (this mainly happens when i move my mouse) as when i sit on the desktop with only mumble open my cpu is on 3% and when i move my mouse this increases to 30%. i have checked my cpu processes and this seems to be due to a process called system interupts. this also seems to be lagging my games after a while whenever i move my mouse. i have tried updating all drivers and have also tried most of the supposed fixes for the system interupts and all attemnpts have failed.
PLEASE HELP !

i also have a cm storm spawn mouse and a razer black widdow ultimate keyboard if it helps,
Thanks in advance,
