plugplay svchost.exe constant 50-90% CPU usage

I've had this computer for about 6 months. About a week ago, it started to slow to a crawl. Particularly Windows Explorer, the control panel, etc. would take forever to load. I've noticed that Firefox alone seems to be unaffected by this. When I bring up Task Manager I see that the process responsible is svchost.exe (service Dcom Launch). I can't end process or stop the service, but I know this is definitely not normal. When I did end the process, my computer behaves like it once did, for a few seconds before it automatically logs me off. When I end process, it also mutes my computer before logging off. I've tried searching for solutions online already and each case of this seems to have it's own cause and solution. I have the HiJackThis log if that would help.

Please help me, I can't stand having to wait 20 minutes for something that should be instantaneous. The way my computer is behaving is unacceptable. Thank you for your help.

Here's the log.

(Edited)

It wasnt meant to be just stating a fact
i put my logs up and 2 days later no replys ,perhaps comp-illiterate would be better going elseware unless hes lucky
get my drift

everyone who helps on here , weather its a little or a lot are volenteers and have lives , families , etc outside CH with other things to do

if your not happy with CH and the fact you had to wait a whole two days , you will find lots of forums were you MIGHT get help

Okay, I did that. Now what?

Here is the log it gave me after it finished quarantining:

My computer's still going very slow and svchost.exe is still taking 50-90% CPU. What is my next course of action?

Okay, I've downloaded Process Explorer and it's definitely DcomLaunch and PlugPlay.

Here are the particular threads causing the problem:

TID: 3904  RPCRT4.dll!RpcBindingUnbind+0x500
TID: 3600  RPCRT4.dll!RpcBindingUnbind+0x500
TID: 4732  RPCRT4.dll!RpcBindingUnbind+0x500

TID: 5092  RPCRT4.dll!RpcBindingUnbind+0x500
TID: 3036  ntdll.dll!RtlRealSuccessor+0x1a0


What do I do now that I've found what's causing it?

Does anyone know what I should do now? Please help. I've been tearing my hair out for a week trying to fix this and get my computer back to normal. I'm on my knees begging for help. This isn't a problem someone without special knowledge (like me) can fix.

Sorry for the delay. We can't get to everyone as soon as we would like to.

Try not to restart the computer until one of the tools we use does it for you or tells you to.

Please download and run the below tool named Rkill (courtesy of BleepingComputer.com) which may help allow other programs to run.
 
There are 4 different versions. If one of them won't run then download and try to run the next one.
 
Vista and Windows 7 users need to right click Rkill and choose Run as Administrator

You only need to get one of these to run, not all of them. You may get warnings from your antivirus about this tool, ignore them or shutdown your antivirus.

* Rkill.com
* Rkill.scr
* Rkill.pif
* Rkill.exe

* Double-click on the Rkill desktop icon to run the tool.
* If using Vista or Windows 7 right-click on it and choose Run As Administrator.
* A black DOS box will briefly flash and then disappear. This is normal and indicates the tool ran successfully.
* If not, delete the file, then download and use the one provided in Link 2.
* If it does not work, repeat the process and attempt to use one of the remaining links until the tool runs.
* Do not reboot until instructed.
* If the tool does not run from any of the links provided, please let me know.

Once you've gotten one of them to run then try to immediately run the following.

 
Download and run exeHelper

* Please download exeHelper from Raktor to your desktop.
* Double-click on exeHelper.com to run the fix.
* A black window should pop up, press any key to close once the fix is completed.
* A log file named log.txt will be created in the directory where you ran exeHelper.com
* Attach the log.txt file to your next message.

Note: If the window shows a message that says "Error deleting file", please re-run the program before posting a log - and post the two logs together (they will both be in the one file).

----------

If you already have ComboFix be sure to delete it and download a new copy.

Download ComboFix© by sUBs from one of the below links. Be sure top save it to the Desktop.

Link #1
Link #2

**Note:  It is important that it is saved directly to your Desktop

Close any open Web browsers. (Firefox, Internet Explorer, etc) before starting ComboFix.

Temporarily disable your antivirus and any antispyware real time protection before performing a scan. Click this link to see a list of security programs that should be disabled and how to disable them.
 
Double click combofix.exe & follow the prompts.
Vista users Right-Click on ComboFix.exe and select Run as administrator (you will receive a UAC prompt, please allow it)
When finished ComboFix will produce a log for you.
Post the ComboFix log in your next reply.

Important: Do not mouseclick ComboFix's window while it is running. That may cause it to stall.

Remember to re-enable your antivirus and antispyware protection when ComboFix is complete.

If you have problems with ComboFix usage, see How to use ComboFix

Okay, I've been reading around and one site suggested that I uninstall all audio devices and drivers by going to device manager (none of them legacy or codec). After I deleted two ATI HDMI audio and one Realtek and uninstalled Realtek using add/remove programs then restarted and the problem went away.

However I also have no sound. I downloaded the drivers for the audio card that came with (and is still in) my computer from the computer manufacturer site (Gateway). When I tried to re-install, I got an error message:
Error 0x000005b4

I'm sorry but I completely overlooked this post. My apologies, I will now do as requested. Thank you for your help.

Here's one.

I'm not getting any logs with any of the Rkill applications, and Combofix says it's incompatible with Vista. Would running them in safe mode be better?
