Windows 7: Device error code 12. How do I free up resources

Device error code 12. How do I free up resources

My original post was in the audio section because I am having issues getting the HD audio working on my "new to me" Nvidia GT-430 HDMI port. That post is here:

However, I believe it is a resources problem so I thought I would try my luck here.

I have an HP z556 home theater PC. It is running Windows 7 Ultimate x86. The video card, again, is an Nvidia GT-430. I can't get windows to recognize the Nvidia audio device in the sound manager. I was just looking in the Device manager and there happens to be a "High Definition audio controller" that is in error. It has a code 12, meaning that it doesn't have enough resources to work. I think this is for my video card because it is the same location as the video card.

So, there were a total of 2 High Definition Audio Controllers, one that works the on-board audio and this one that is in error. I disabled the on-board, rebooted and the error didn't go away. How can I free up resources so that I can get rid of the code 12 error?

Let me know if you need anymore information so that I can help you to help me. Thanks!!!

Well without going into any great depth Hazards mate you haven't got a lot in RAM installed on that board I think you would if you can get at least 3GB and preferably 4GB installed for starters. I know it is hard to get hold of and is getting expensive but the RAM is a bottleneck when it comes to running the machine, and especially as you are running Ultimate it as a general rule needs at least 4GB RAM.
The hard drive is also a tad small and I am guessing fairly old? Plus this is telling me he minimum power requirement too - 300watts now that is a fair slug of power and I would suggest you look at my little ditty and see what the PSU is doing and also run the power calculator to see what all the components all up are needing in power < use the light version. Post back what it tells you.
If possible please send a pic of the readout as in my pic for the volts on that PSU.
Using HW Info
You can test the volts on the PSU with HW Info HWiNFO, HWiNFO32/64 - Download < download the right bit version and close the right hand window select Sensors and scroll down to the power section where you will see what the volts are doing see my pic.
The original right hand window shows the machine running and is handy for that but for looking at the components in some detail close it and use the main left hand side panel
Open each small square with + in it on the section the components are in and then click on the individual component/s (it will highlight in blue) - in the right hand side will appear all sorts of details including brands speeds and other essential info that particular device. See pic for example.

That HW info is a pretty sweet program.

So, eXtreme Power supply calculator says I need at a minimum of 283 Watts. This is higher than the 250W power supply that comes in the z556 HTPC. I don't have a chance right now to pull the case apart but I found a picture online of a power supply exactly like mine. I have attached the picture. I also attached a picture of the sensors.

The hard drive is small compared to hard drives these days but I'm still way under 50% usage.

With regards to the RAM, 2GB is all that is allowed on this MOBO and watching the task manager, it doesn't look like I'm taxing those 4 sticks either. Otherwise since I'm running win7 can I do more?

With regards to the other pictures I attached, I am hoping that they will say a lot more than me typing. Thanks!

Ok well done Hazard and yes it is a good program to keep for fiuture use.
Now the PSU issue mate I hate to say it but you really have to buy a good brand named one those ones are ok but really the cheaper ones do not have the capabilities or inner circuitry to do justice to your system. The volts on that one are fine but the amps are out mate you can work that out using Ohms law - that is watts = volts x amps So if you have a 12 volt rail at 25 amps then you will get 300 watts of power available and it is the 12 volts rail that is important as it supplies a lot of different high use components.

On the side of the PSU you can see the different voltage rails and you only have to multiply the volts by the amps to get the watts see pic

Now I would aim for at least one of 350 watts capacity and preferably 400-450 watts as that gives you plenty of leeway. NOw I am a great fan of Corsair PSU's but there are others that are good lie Seasonic for example. see this one and you can see for a little price you are getting stacks of power and a good PSU brand CORSAIR CX series CX430 430W ATX12V v2.3 80 PLUS BRONZE Certified Active PFC Power Supply -

Now it is a pity about the RAM and well if that board only supports 2GB then that is that because the Ultimate is a RAM hungry OS.

PS I meant to say if you are going to get this or another one look at what are known as modular PSU's they come with attachable cables and so you don't have "extras" hanging around. Mind that M one is $12 more
