10. Go to start > Run and type MSCONFIG. Then choose 'Selective Startup' and UNcheck the box labeled 'load Startup Group'. (You can also manually configure the Starup items by going to the Startup tab in MSCONFIG and unchecking extraneous programs.) Once done, click Ok and reboot the computer. 

There also could possibly be a hardware conflict. Go to Start > Setting > Control Panel >System > Device Manager, highlight 'computer' and hit properties (or Start > Control Panel > System > Hardware > Device Manager > View Resource by Connection in windows XP). You will now see a list of Interrupt Request (IRQs). Ideally, your sound card an IRQ is to physically move the card but you can also configure settings in the the BIOS. For further information, contact the hardware manufacturer. 

If none of the above options resolves the problem, you should reinstall the newest drivers for all of your MIDI and Audio Devices. To further troubleshoot the problem, you may wish to disable these devices (one at a time) in window to see if you can narrow it down to a particular piece of hardware. 

This should eliminate any software irregularities that are causing your problem, but let us know if it does not.
