I am very computer illiterate, and could really use some help fixing these issues. The speaker in the task bar has a red X, and when I click it a box pops up that says "Detecting Problems". Then is says "Troubleshooting couldn't identify the problem". As for the touchscreen issue, there is no Pen and Touch" listing in the control panel.
