BleepingComputer.com: Inconsistant Boot

After a successful boot I can't effectively run aps or get on-line for over 5 minutes because SVCHOST.EXE and MSCORSVN.EXE processes will be running and using 100% of available CPU resources. Its almost as if something is trying to read all the files on my HD. After 5 or 6 minutes CPU usage drops to less than 3% and everything runs as it should.
My system consists of a 2.0 gig pentium 4 with 1.25 gig ram and a 80 gig HD 75% free and a 40 gig slave.
Can someone advise me as to just what these executable processes are and what they do. And can I safely delete them?
Thanks for your help

svchost.exe is used to run Windows services on startup. This is an essential Windows file needed for proper working of Windows and cannot be deleted.

I presume you are talking about mscorsvw.exe and not mscorsvn.exe
mscorsvw.exe is used to compile native .net assemblies when you install .net framework for the first time and also .net dependent programs. This process consumes alot of CPU. It is not advised that you delete this file. If you want it to compile all assemblies at once and then stop, then open Start Menu > Run and type cmd and press Enter. Then type the following and press Enter in the command prompt window:

ngen.exe executequeueditems

This would cause all assemblies to compile all at once (your CPU would cry) but after that mscorvw.exe would shut down for it has nothing to do.

Romeo,
Thank you for the info.
But before I attempt this, a little clarification please.
START_RUN_CMD=black control panel labeled C:\WINDOWS\system32\cmd.exe
In the body of the window is C:\documents and settings\admin>

So is this where I type in the code?

Chuck

Yes this is where you type

Romeo,
I typed in the code and got the following response:
'ngen.exe' is not recognized as a internal or external command,operable program or batch file

However search found the following:
NGEN.EXE-38021CCC.pf in folder C:\WINDOWS\Prefetch
ngen in folder C:\WINDOWS\Microsoft.NET\framework\v2.0.50727
ngen in folder C:\WINDOWS\Software Distribution\Download\9866fb57abdc0ea2f5d4e132d055ba4e

So, is there anything I can do with these files that might help?

And thank you once again for your advice

Chuck

Sorry I forgot to tell you to type cd C:\WINDOWS\Microsoft.NET\framework\v2.0.50727 before issuing that command.

ROMEO,
Sorry to inform but something isn't just right yet.

System failed to find the file specified (Exception from HRESULT: 0x80070002)

Is it possible that the code you specified is at fault. IE: does the letter u just before editms belong there?

Thank you again for your time

Chuck

Romeo,
Sorry, my bad.
I typed editms rather than editems.

After entering the correct code I get the message: All compilation targets are up to date.

So I guess there's nothing more I can do about this.

Thanks again for your help.

Chuck
