Aspire F-15 Sound issues (Feedback noise)

FinlandAdventures

Recently, my Aspire F-15 (F5-572G-709N) has been suffering from some sound issues. First it was that it sounded like the microphone was picking sound and feeding it back through the laptop speakers. Even if I switched my microphone over to an external one, the internal one still had a sort of reverb sound.

Today, I had to completely disconnect from a call with my daughter, as the system kept giving that high-pitched screeching noise, even after restarting it. I tried to use Teamspeak after that, and it continued to give out feedback, and nothing seemed to stop it, not even switching to external headphones and/or microphone. I ended up disconnecting it and plugging in a secondary laptop to continue the conversation. 

Any ideas what might be causing it and how to fix it? It's *just* gone out of warranty with the place I bought it from (of course).
