Not sure if this should be in hardware or software, mods, you may move it if needed


System: Dell Laditude D620 Business Laptop {Reformatted drive with Windows XP Professional over Vista Business}

Hard drive: 80GB

RAM: 2GB {doubled from 1GB one month ago as of this post}


Trouble: Windows Audio service hogging up the CPU resources that are not in use.


OK, here's my trouble.


I recently replaced my 1GB ram with a brand new set of two 1GB sticks doubling the ram in this laptop. exactly 24 hours ago {as of this post} One svchost began overloading my CPU up to 50% used when everything else is using very little of it. Normally I;d think nothing of it and not care, but I keep my Windows Task Manager near my clock at all times incase I need to kill a proccess in a heartbeat or less.


So naturally I kill that proccess when CPU use got to around 55% or more for that single proccess. Then my audio shut down. So I restarted it, Once more that same svchost is sucking up CPU reserves up to around 55-60% in use. with 2GB ram this is not too much of a problem, but I am used to having my CPU running at barely 8-12% even with ten tabs open in Google Chrome.


Seeking advice of what to do at this time of how to fix this really quick. I thought restarting might do it, but I am currently scanning with MBAM at this time.


Its nothing too major, it is just starting to worry me.

Question: Why buy more 'resources' if you're just going to get upset when the computer tries to use them? ;)

I think OP is talking about apples (CPU) and oranges (RAM).


CPU usage on a system as reflected by Task Manager...will vary according to the program and what it's doing ,  When I edit video, my CPU usage for that editor climbs to 50-60% or so per Task Manager...while rendering edited video.  To my knowledge, that's the only program I have installed which does that...and I understand that it's because rendering video is a CPU-arduous task. 


I don't even pay attention to memory usage in Task Manager...there's no point because I have 8GB installed...plus a pagefile...and even if XP only handles 4GB, that's more than enough for anything that I do.


Think about this...System Idle process in Task Manager is a way of telling you "this much of your CPU is not doing anything because it doesn't have to."  System idle process numbers will probably never be zero or near-zero, IMO, unless something truly unusual is going on with your system.  I've never seen Windows give any warning re low or high CPU-usage...the warnings, if they come, all have to do with "insufficient resources" (not enough RAM) or something related to RAM/memory.


If you are concerned about servicehost processes...you can explore those by using tools like Process Explorer Mini-guide and Screenshots - http://www.bleepingcomputer.com/forums/topic354690.html and Process Explorer - http://technet.microsoft.com/en-us/sysinternals/bb896653.aspx .

What is the Host Process for Windows Services The Mysterious Svchost.exe Windows Host Process - http://www.brighthub.com/computing/windows-platform/articles/45450.aspx


Until a system has a problem...I see no need to monitor anything going on in Task Manager, unless it's strictly idle curiosity.  Idle curiosity is the only reason I ever looked at CPU-usage when rendering and I didn't bother to note the RAM-usage.
