You might have a buggy third-party program or a hardware driver loading at startup that is running as a service, and it is listed under an instance of svchost. Svchost is is just a generic host for other processes that are loading from DLLs.

Running the Tasklist /SVC command might help you sort out which file or program is using so much memory and/or processor time.

The only process that should be using a large amount of processor time is the System Idle Process, but the memory demands for this process are supposed to be low, such as 20K.

A typical example of a program that might cause a problem like this is a firewall, like the WinGate Internet Client. For hardware, a Visioneer USB Scanner. It could also be caused by spyware, or a trojan horse that has infected the system.

ok, I ran the command Tasklist /svc and found that the svchost that is taking up the cpu and memory on my computer is running the following programs:

Audiosrv
Browser
Cryptsvc
Dhcp
lanmanserver
lanmanworkstation
messenger
netman
Nla
Schedule
Seclogon
SENS
TrkWks
uploadmgr
W32Time
winmgmt
WmdmPmSp
Wuauserv
WZCSVC

Any thought as to which on of these is sucking up my system resources and what I can do about it? Thanks.

On my system, the instance of scvhost that is running a similar set of Services has a PID of 604, and this is what is listed:

AudioSrv - Windows Audio
Dhcp - DHCP Client
dmserver - Logical Disk Manager
EventSystem - COM+ Event System
helpsvc - Help and Support
lanmanserver - Server
lanmanworkstation - Workstation
Netman - Network Connections
Nla - Network Location Awareness (NLA)
RasAuto
RasMan
SENS - System Event Notification
ShellHWDetection - Shell Hardware Detection
srservice - System Restore Service
TapiSrv - Telephony
Themes - Themes
uploadmgr - Upload Manager
winmgmt - Windows Management Instrumentation

This totals up to 12,960K, with 00 CPU usage.

I have three other instances of svchost. They each run one program, respectively: RpcSs (Remote Procedure Call), Dnscache (DNS Client), WebClient (Enables Windows-based programs to create, access, and modify Internet-based files). Combined, these add up to 9,844K, with no CPU usage.

RasAuto and RasMan are for my Remote Administration program, which is running as a Service due to personal preference, which is why you don't have these listed.

The basic differences between your system and mine are:

Browser - Computer Browser
Cryptsvc - Cryptographic Services
messenger - Messenger
Schedule - Task Scheduler
Seclogon - Secondary Logon
TrkWks - Distributed Link Tracking Client
W32Time - Windows Time
WmdmPmSp - Portable Media Serial Number
Wuauserv - Automatic Updates
WZCSVC - Wireless Zero Configuration

I don't see anything in your list that is a third-party service, or based on a DLL. But you do seem to have several unnecessary Services running that can eat up a great deal of memory. And one of them is taking up too much of your processor time.

Because of this, I suggest you edit the Administrative Services List. You'll find some excellent information on editing specific Services on each of these three websites:

I hope this helps!
