turokisme :
Ok I'll run MEMTEST, but I don't know how to update the bios or the drivers on the mobo.
Other should I uninstal all (or most of the stuff that came on the disk?
Sorry for the delay:
I'm still not sure you have a problem, because as I've said every game does stutter. If you mean a massive, 1-second FREEZE then no, that should not happen.
The only other thing I can think of is to LOWER THE QUALITY whilst also leaving VSYNC ON:
1) reduce resolution and quality to LOWEST settings in Dirt 3, while VSYNC ON (Fraps shows 60FPS)
2) Any stutter?
3) If no stutter, raise the quality level and resolution.
If you get no stutter at the lower quality settings then it may be an issue with either the graphics card, PSU, motherboard or even RAM. Probably the video card if it is a hardware issue.
If it is a HARDWARE issue, this should be repeatable with almost ANY GAME or benchmark, though VSYNC may have to be OFF to provide enough stress. For example, if GAME A can run at full quality at 120FPS with VSYNC OFF, then with VSYNC ON your GPU stress is much lower than a game that can only hit 70FPS with VSYNC OFF.
Not much help I know.
The only OTHER thing I can think of for troubleshooting is a hassle. That is to REPLACE, the PSU and Graphics Card. The motherboard is too much hassle and a last resort. You could try the memory one stick at a time though (see motherboard manual for the slot) though MEMTEST should rule that necessity out.
Updating BIOS:
See your manual. The easiest method is usually:
1) Install the BIOS software (motherboard support section)
2) Download the latest BIOS file (same section)
3) Open the BIOS software, select UPDATE, and then browse to the folder you download the BIOS file to...
Updating motherboard drivers:
1) go to the motherboard support section
2) Find the driver that sounds like the MAIN CHIPSET, download, and RUN it
3) Run any other drivers that seem relevent (the main chipset driver is the most import).
*You can also go to INTEL and find the support section which can autoscan your system to suggest an updated driver for any Intel chips. Fairly easy to find, will install some software first.
Uninstall software?
I see no reason to do so.
SUMMARY:
I'm not sure what's going on. If it's a massive FREEZE it sounds like a hardware issue, possibly the graphics card. If it's a tiny stutter that may be normal, but I get no such skip or freeze when I run Dirt 3.
If nothing helps, I can only recommend trying several games then contact the graphics card manufacturer with the info that "all ten games freeze for about one second" or whatever is happening, and see about swapping (RMA) the card.
