Depending on your system, you may not have a mic boost option in Windows. Go to Control Panel>Hardware and Sound>Sound> Click under the "Recording" tab, then locate your active microphone. It will be the one with the microphone level indicator beside it. Double click that tab and then click on the "custom" tab. If you see a microphone boost there, enable it. After it's enabled, set your boost to max. If you have boost, that will fix ya up. If you don't see the boost feature, you may need a different sound card (or possibly a driver for your current sound card) that has a boost feature.
