SVCHOST.EXE using 100% CPU

svchost.exe is using 100% cpu usage an making it hard to do anything.

I have reinstalled win xp that did not work.

I have formated the comp an that worked for a bit then it just starts doing it again.

At current i have 4 svchost running an 1 im not sure about is called scvhost.exe an system is using 40% of cpu.

i have 2200amd asus a7n8x deluxe mb 256 ddr

This only started when i got my new video card asus gf fx 5200.

Previously i have had the blaster virus if this helps but during that time an now i have done atleast 5 full formats due to frustration an my video card lagging.

Can someone help me out here plz with really detailed instrutions plz.

TY kojak


I have tried this answer an now i can actually end task svchost.exe but after like 2min it starts up again. Where as before if i were to close it my comp would shut down.

Click Start > Run. (The Run dialog box appears.)
Type:

SERVICES.MSC /S

in the open line, and then click OK. (The Services window opens.)

In the right pane, locate the Remote Procedure Call (RPC) service.
--------------------------------------------------------------------------------
CAUTION: A service named Remote Procedure Call (RPC) Locator exists. Do not confuse the two.
--------------------------------------------------------------------------------
Right-click the Remote Procedure Call (RPC) service, and then click Properties.
Click the Recovery tab.
Using the drop-down lists, change First failure, Second failure, and Subsequent failures to "Restart the Service."
Click Apply, and then click OK.

so not select " Restart the service".Just select " Take no action ".Press ctrl+alt+delete and click on processes.Then find out the svchost.exe that is 19800 kb in size and does not run for either " network" or " local service" but runs for "system".That should clear up.Well,it has worked for me i don't know about others...

Ok i fixed it.

I used a blast virus remover which didnt find anything but i applied the blaster patch an all is sweet now.

EDIT: i lie when i connected to the net it started up omg.

where is the blaster patch thing that fixed it cuz my blaster fix didnt find it either

well svchost only uses 100% cpu only when im connected to the net now instead of as soon as the comp boots up.

Just type blaster remover in google an then blaster patch in google. Microsoft.com an nortans website have them.

That link above go directly to the specified problem but ahwell ill keep looking for it.

If someone that has fixed this problem can you plz post direct links to instructions over even post them here plz.

I have had this problem on win xp and 2000 which is what i have now with the same problem, the closest thing i have found for a fix is a program called processxp from www.sysinternals.com that will show the child programs of svchost and u can close the one that shows high % but since u closed svchost some stuff doesnt work right i have noticed periodic internet activity problems and some other stuff acts funny.pretty funny as a matter of fact but its better than 100% cpu usage. Something i just tried but im not sure is going to work is with that program u can open the child svchost program and it shows all the threads and their cpu usage then close the high % ones there. That way svchost is still working but u stopped the problem thread, mine was a remote procedure call which sounds like blaster but ive tried all the removals and patches.(the threads popped up 1 more time after i closed em but they havent come back for a while now) its been working good for about 20 mins on the net now (which is when mine happens too, never offline).Ill let u know if it keeps working after a day or so. hope it helps you.

I have had this problem for ever and it is very annoying and i think i might have finally fixed it, of course ive thought that about 20 times

Well it sort of works, all the basic stuff works and internet, but when i try to play a game online for some reason every 5-10 mins it lags out for a minute or so

I have been reading all day about the SVCHOST issue where folks are experiencing 100% cpu activity for a while as soon as connecting to the internet. My fix is limited to the situation outlined below and does not include the 60 second shutdown issue or crashing.


Some websites and forums suggested that SVCHOST is being exploited by a worm or trojan, but most people find their virus scans come up empty as do the spyware checkers. So your computer is mostly OK except for this cpu drain that seems to last only a short time.

I have had the problem for about a week and I have tried five different virus scans (including on line McAfee, AVG, PC Security Shield, and Symantec) and two spyware programs (Adaware and Xoftspy) but found nothing of import. My "Hijack This" log has not changed. It started after a recent Microsoft Automatic Update to my Windows XP SP2 system. So if you dont have a virus, and still have this problem, here's what I did.

Using Process Explorer (from SisInternals --
http://www.sysinternals.com/Utilities/ProcessExplorer.html
I could see that one of the many SVCHOST copies was running (1144) which was attempting to assist Microsoft Automatic Updates (3108 and 2720). My Automatic Updates was set for "Notify Me but do not download or install". Apparently the cpu usage is caused by the Updates program attempting to determine if there are updates which it of course only does when you connect to the internet. I simply set my Automatic Updates to OFF and the problem disappeared. I did not experiment with allowing it to be ON full automatic mode, but I suspect that would be OK too. Appears to me that Windows is not playing nice with the Notify me but do not download option.

Wanted to let you know cuz lots of folks are suffering. I suspect this is something MS will be fixing in a future update.... When you start your machine, immediately start the Process Explorer, and watch the cpu usage as your internet connection is established. If you see that the SVCHOST that is causing the CPU load has underneath it (below the minus sign associated with it) one or two Automatic Update listings, then try my fix by either shutting off Automatic Updates in Control Panel (Automatic Updates).

MS has finally fixed ALL the bugs relating to SVCHOST. The patch can be found at:

http://support.microsoft.com/default...;EN-US;Q927891

It's an update to the same patch released a month before, which actually didn't work for me. After installing this new patch it's fixed this problem which I've been having for a year now and has prevented me from using Microsoft Update and would randomly lockup up the PC about 3 times a day!
