Every cable is plugged in and no unplugging or extra hardware has been added, I did have a windows update lastnight but I went to "restore point" and restored the comp back to last night setting and it completely ****'ed my computer up. Computer lights were on and fan spinning but monitor had no signal input and switched to standby. Just took me 90 minutes to fix it. All I done was unplug everything, dust the internals and plug it all back again and it works fine now but still no sound.
Anyone know what the problem could be ?
