Hi folks,
I'm experiencing a strange performance drop on Windows 7 which I've been unable to diagnose. Quite frankly, I'm unsure where to start diagnosing this particular problem.
Setup
Windows 7 Ultimate SP1
Phenom II X6 1055T @ 2.8Ghz (factory)
MSI 970A-G45 (MS-7693)
8Gb DDR3 PC-10700
ASUS GeForce GTX 550 Ti 1Gb
OCZ-SOLID3 120Gb SSD
Dual BenQ GL2250
Problem
Under normal working conditions, the machine 'jitters' for a second, where performance drops noticably, almost like a short freeze. After this happens, performance is much slower on all applications. Games in particular are vastly slower. On WoW for example, where I would expect 50-60 fps, that framerate drops to ~10fps. Flash games fps drop considerably. Browsers, office applications, authoring applications all take time to respond where they would normally be very responsive. Closing all applications makes no difference, the behaviour continues like this until a reboot, where the performance returns to normal. There are no events in the event logs around the time of the incident. It does appear to happen most often when the machine is under load; for example gaming or using resource heavy applications.
I'm at a loss as to how to diagnose this particular issue. Can anyone suggest how to determine what the cause could be?
Many thanks,
Baps.
