This is an annoying problem. Whenever I try to adjust the sound on my laptop, the whole think locks up and I am unable to click/alt-tab things. I blame myself for buying a Compaq. I feel like an idiot for buying a Compaq anyone who reads this and proceeds to buy something made by Compaq should be mercilessly slaughtered. When I restart my computer, I have a short window of time where the sound adjusting works perfectly. My theory is that my Sound Card goes completely bug-fusk when a certain thing starts up. My issue is not being able to figure out just what this is. Not only do my sound buttons not work, but adjusting it through the PC itself will also have the same effect. I thank anyone who reads this/takes the time to help me out.
