Spec: e6300 ga 965p s3 2gb ocz platinum ram 520w corsair 7950gt 512mb Right the problem im having is every one to two minutes whilst im on my pc it suddenly slow down for a few seconds. For instance my music will slow and then speed back up again or my mouse will become juddery. I have ran multiple scans of everything i can lay my hands on even in safe mode but it cant find any virus/spyware. All i can see if that when i open task manager and order the processes by cpu usage. When the system slows down a task called "system" which is around 250kb mem footprint jumps to the top of the list and is only using 3 to 5% cpu usage. This occurs so fast i have to screen shot it to make sure it is indeed this process. It then disappears back to the bottom of the usage list and the system resumes to run fine. Any ideas?
