It's not that new but an extra stud can short something out. It's one of the usual issues. Be sure to pull the mainboard and check.
Hello, thanks for looking at this. I have been struggling all week trying to fix this and have decided to ask for help. I was recently given a Sony Vaio Desktop VGC-54G by someone. This computer ran great but the case was so tinny that it was getting ever hot and the fans were running like crazy. I decided to pull the guts out and put them into an older bigger case I had this also allowed me to add another HDD. All was fine when I shut down the computer and after installing everything I was excited to turn it on. When it booted It did not have any audio and much to my surprise the internal audio device was gone. I have tried loading drivers from Sony Vaio page for audio and have reinstalled the bios hoping it owuld force it to detect. I have checked my bios settings and my onboard audio is enabled. I have downloaded CPUID, Smart Driver, Driver genius, and a couple of others and all to no evail. (cpuid is not an updater i know ) This system was running win xp sp2 until i upgraded to win 7 but I did this AFTER the audio stopped working. I have read every forum site and am going insane trying to figure this out. If I can not figure this out today I will cave and buy a sound card. Also windows will not detect any audio devices but my web camera Thanks for any help
