Please help me with this. All PC games has stutterings in frame rates in when onboard USB is enabled in the BIOS. Worst is on UT3, Crysis is not so bad, Far Cry 2 went bad after speeding into another zone in a jeep and got into gun fights to another jeep. Same result when games (graphic and detail) settings are changed to lowest level.
Rig spec:
Athlon 6000+ 3Ghz real clock, 15x CPU multiplier on 200 CPU clock.
motherboard GA-MA78G-DS3H, BIOS version F6.
VGA card is Asus HD 4850 512MB.
Windows 7 Ultimate SP1 32-bit.
Kingston DDR800/PC6400 RAM 2GB x2 modules, 2 sticks on dual channel (4GB). CPU-z shows RAM at CPU/8, 376.60Mhz.
I set the RAM to DDR800 in the BIOS, but it seem to run on RAM divider as shown in CPU-z.
Last owner of the PC has set the CPU at 5x CPU multiplier on 200 CPU clock. I didn't know that when I installed the OS.
I used USB mouse when the OS is installed. Then changed it to PS/2 mouse on the next day.
I've installed all the latest drivers downloaded from the Gigabyte web site, though I couldn't see any drivers for the USB part. I've not install any drivers from the mobo's driver CD disk, 'cos I think Win 7 should be updated enough for USB 2.0.
I've installed the latest version of DX9.0c and SDK/DX10/DX11.
Thanks
