Hi clarck24 and welcome to TSF.
What Service Pack do you currently have installed as the 0xc0000409 error can point to a .asp issue that may be resolved by having the latest Microsoft .NET Framework 4 installed.
With regards your audio issue, do you have the latest up to date sound driver installed for your computer? A program could have knocked it out/ damaged it, and it may need re-installing.
Can you check your Event Logs for any errors in red, Right click on 'My Computer' and select 'Manage', in the window that opens, select 'Event Viewer' and report any errors in red in 'System' and 'Application'.
Could you also give us your full system specs as well. If you are unsure what your specs are, download and run Speccy, then when it's generated the information (about 10 seconds) go File>Save as text file, and attach that as well.
