Its a fresh install of Windows 7, i had to do it to fix my original problem =/
Update: I changed the RAM and put them in the slots u suggested, no change.
Sorry, when i post my last anser, i didnt know your new problem
Sounds like old problem from time of XP to Vista.
Firsth. Take out that USB connection of your headset from PC.
Secend. Uninstall any driver that headset (or you) may have installed to your OS.
Third. Run registercleaner program.
Fourth. Shotdown PC and then start again (dont just reboot!)
Fifth. Download and/or Install drivers for that USB headset.
Sixth. Reboot that PC.
Seventh. Insert that USB connection.
I hope this helps! Cheers, Mummy
If not i would try to ubdate intel chipset drivers(if MSI ones dont work, i would go to Intel site and try them from there) and if those dont help then another reinstall of OS and member to inser USB device after installing drivers for the device.
