It screwed up for my brother (Apparently flickered abit, and then worked fine again), he reckons it happened when a message came up saying there was low space on C: drive (Which there admittedly is
) and now no sound works on my computer. We've tried multiple speakers, and they don't work but work on other computers and with my Mp3.
I can't work it out. Is it just a case of resetting something? Or has my computer screwed up forever? Or will I need to re-build the computer?
Help. Please. All sound has gone.
