Hello everyone. Well, a couple of days ago I've been trying to fix apparently a "missing sound problem" on my computer. I did many things before contacting experts on the Audio & Video forum, they told me some other things to do to try to solve the problem, in those things were getting a malware program to scan my computer. I tried downloading many different programs, such as antivirus and malware programs but my computer won't let me install any of those. I hope anybody can help me out on this problem because as of right now I can't afford it to take it to "Geek" experts and I wouldn't like to format computer because I have some important information, but I'll leave this last option as an extreme emergency. Thanks. Regards.
