Stability Issues Help Please!

Hey, my rig is about a week old and I've been having stablity issues without and recently they have become pretty bad. Firsty (the most annoying one) whenever I play back a file in windows media player in xvid it stutters for 1 second every few minutes... I thought it was a CPU problem so I ran task manager and CPU didnt ever spike and was a low constant % throughout playback.

Also during games it tends to freeze when playing AOE III and HL2 but not FEAR for some strange reason. I have latest drivers for pretty much everything.

It might be a software problem because I have both ntune and aibooster installed and they are both monitoring and adjusting the system (i think).

It might be a tempreture problem as I use qfan to keep system noise down... I get temps CPU 39 CHA 39 GPU 45 idle, I dunno what load temps I get. I tried disabling Qfan and going to stock speeds but that didnt help.

The thing is though, when I look at AI Booster the CPU Clock speed fluctuates!! I dunno if this is normal but it may be why this is happening. It fluctuates from 2190 to 2210 when idle. I have no idea why. Maybe its normal.

Try uninstalling AI Booster and restart, see if you get the same problems when its not there.

Other than that I would say make sure you have the latest motherboard drivers installed

Could it be your anti-virus checking the video files? Check the extension black/whitelist.

As these run at a higher priority then most other things they can block your PC once in a while. However don't lower the priority or all the on-access scanning will slow down too ;)

have you checked the Bios to make sure you are on the 'Stable' settings and not the overclocked ones as this can cause problems on my system.
