I'm having an incredibly frustrating time trying to fix a royal screw up that happened to me very recently, and am at my wits end trying to solve it. I really hope someone here can help me.
My computer is an HP. I noticed that graphics card (NVIDIA GTX 550 TI) had a driver update, so naturally I started to install it. Fate flickered my power in the middle of the install, and when my computer restarted, the screen refused to come on. Great. I booted with safe mode, and tried to install the driver that way, but it wouldn't work. Welp, I have a save state just before the install, so lets just roll back! Roll back worked, screen is fine now, but my sound refuses to work. Speaker Icon in the lower right corner has the red x over it, and I can't figure it out. So far I have...
Reinstalled the audio driver on the NVIDIA card.
Uninstalled all sound related drivers and reinstalled them.
Jiggling the handle.
Cursing
Nothing has worked so far. If anyone can give me a hand, I would greatly appreciate it.
Install the audio drivers. The HP site should have a driver package for the audio chipset.
The nVidia HD audio that you are referring to is the audio chipset for the HDMI port. So you should likely see at least two audio chipsets listed in Device Manager.
Also, when I highlight the red x, it reads 'NO Audio Output Device is installed'. Which, if it means speakers, it is totally lying. I got those. Hooked up, even!
I'm using Windows 7, and it is 64 bit. The exact information on my computer is as such:
HP Pavilion P6000 series.
Product Number: Bt552AA#ABA.
Model Number: p6674y
I recently installed a previously used driver, but sound still will not work.
(Also, starting up is taking much longer than it used to. After windows screen, I'm staring at a black screen with a mouse icon on it for 30-45 seconds before my background finally shows up. Oh, and I've been getting a few blue screens here and there. So very, very frustrating.)
Check Device Manager and see what hardware is listed. As noted above, you should see at least two audio chispets listed.
Driver issues aside, "hardware not installed" typically means the hardware is not seen by Windows. Which means the hardware is not found or recognized (ie: not installed or faulty hardware).
If it's listed in Device Manager, it's likely a driver issue. If it's not listed in Device Manager, it's likely faulty.
The slow boot would seem to indicate a hardware fault.
It comes with Windows 7 Home Premium 64-bit and has ATI Radeon HD 4200 integrated graphics and has a 250 watt power supply.
The GeForce GTX 550 Ti graphics card that you installed in it uses 116 watts and requires a minimum of a 400 watt power supply.
The most current Windows 7 64-bit driver at the NVIDIA drivers site for that graphics card is 358.50(9.18.13.5850).
The most current Windows 7 64-bit driver at the ATI/AMD drivers site for that integrated graphics device is Catalyst Software Suite 13.9(8.97.100.11).
The driver listed for it at the HP site is 8.733.0.0.
Yeah, I know my power supply is inadequate, but unfortunately I was unable to upgrade to a better one. I haven't tried the ATI/AMD drivers, I'll check those out!
If you're going to stick with that HP generic 250 watt power supply, you should switch to a graphics card that doesn't require so much power and still has a decent benchmark score.
Well, installed the drivers, that didn't seem to help. Oh, and since I haven't posted it yet, this is what I see under sounds/video and game controllers in my Device Manager:
! Microsoft Streaming Clock Proxy
! Microsoft Streaming Quality Manager Proxy
! Microsoft Streaming Service Proxy
! Microsoft Streaming Tee/Sink-to-Sink Converter
! Microsoft Streaming Tee/Sink-to-Sink Converter
! Microsoft Trusted Audio Drivers
! NVIDIA High Defintion Audio
! NVIDIA High Defintion Audio
! NVIDIA High Defintion Audio
! NVIDIA High Defintion Audio
! Realtek High Definition Audio
That would be correct, as I am not all that computer savvy -- thus my seeking help with those who ARE tech savvy. Someone asked what it looked like under my device manager, though, and there she is.
I'm thinking that the more things I try, the more likely it is that the chipset is faulty. I've uninstalled the Realtek and rebooted, and uninstalled and manually reinstalling the Realtek drivers from the HP site AND the realtek site. No dice.
