I bought this computer at the end of June and it's been working beautifully until today. I worked this morning, then took a nap because I'm recovering from stomach problems. I went back to work at 4 pm and there was no sound. Nothing from the speakers and almost nothing through my headphones. I have been trying to resolve the problem unsuccessfully ever since, and I'm a bit panicked since I'm visually impaired and need audio cues to help me perform my job.
When I restart or try to use the headphones, there is a horrible whirring sound coming from the right-hand side of the speaker vent; during restart, there will also be a brief sound from the left side. It stops after a minute or so after a restart, but if I use the headphones it doesn't stop at all until I restart the computer. I actually can't gauge the headphone sound accurately because the whirring is so loud.
The Windows and HP scans can't find a problem, but when I ran the system diagnostics the audio components failed.
I have installed, updated, rolled back, uninstalled, and reinstalled drivers. I have disabled and re-enabled the audio, changed all of the settings, reset the BIOS to defaults, and spent so much time chatting with the virtual agent I'm tempted to give her a name. I have read the repair manual and priced replacement speakers, but since she's still under warranty I don't want to open the case myself!
I really don't know what else to do, although I should probably update the BIOS while I'm at it.
Only one thing has happened to my computer lately, and I don't know how it could be related but will include it just in case: against my wishes, my husband set up an "administrator" account for himself on my computer; he said he was hunting for work while he waited for a part for his own PC, but the other day I caught him messing with my BIOS in some virtual MS3 setup. I chased him off of my computer and told him that I would delete his account as soon as his computer part arrived, but he wasn't to touch mine in the meantime.
Of course, while I was napping he deleted his account and--again without my permission--tried to reset the computer back to factory settings. He did not reset it successfully, but ever since then I have had no audio. Again, I don't know how it could possibly be related but didn't want to leave out anything that might help.
