I've seen how helpful this community seems to be while trying to solve this problem and thought I'd give it a try. I've tried almost everything within my means to solve the above problem, and have got nowhere.
In 3D games/apps and some streaming video (Steam game trailers, Youtube) I am getting a stutter for just a second. It happens continuously at the same intervals I think. In Bad Company 2 it is very noticeable, almost like I've lost a frame or something. In Fallout 3, it's terrible especially in large open areas, where the stutter is constant. It was hardly noticeable in Half Life 2 + episodes, but was defo there, making me think that the newer, more demanding games are exposing this. The system was absolutely fine only a couple of months back and I had no problems with the above - this seems to have started without any reason.
Intel Core 2 Duo E6600 (I have a small AI overclock on this through my MB but only by about 5%)
4Gb DDR2 RAM (Not overclocked in any way)
500Gb SATA 2 HD
ATi Radeon HD4870
Asus P5N-E SLI motherboard
700W Arctic PSU
What I have tried:
I have scoured the internet looking for solutions to this problem that has sprung up and have found many posts but al with different solutions if any at all. I have tried:
- Thorough defrag
- Intel Processor Diagnostic Tool (No errors detected)
- Seatools from Boot disk on HD (No errors detected)
- Memory test from boot disk (No errors detected)
- Tried "Solve Windows Problems"
- Tried clearing temp files etc
- Removed overclock on CPU
- Tried different SATA port
- Changed monitor
- I've double checked BIOS settings but am open to suggestion.
I would be eternally grateful if anybody could help to get to the bottom of this software-wise, or help me pinpoint any potential hardware issue.
Thanks in advance,
