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. 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 formats due to frustration an my video card lagging. Can someone help me out here plz with really detailed instrutions plz. TY kojak

You may have gotten the blaster virus again... u should make sure to use the patch for it. I have found 2 MS patches. Apply those before u plug in the network right after u format. This may fix it. or it may not.. ither way it's a good idea to install those patches. Matt|ttaM

Go to BLKVIPER.COM and disable the services you don't need. When I had the the problem it was DNS client. Rgds.

Well Kojak, I had the same problem after downloading a windows update. It turned out to be as gabep said. My DNS client was turned on by the update and interferred with my spyblocking software sending my cpu usage to 100%. I was told by my spyblocking software support to uninstall the spyblocker and reinstall and that will shut off the DNS client. It worked and I have had no more problems. I think you can also turn off the DNS Client in services under computer management in administrative tools.

well i have used the blaster remover program it didnt find the virus. I applied the patch an that did the job UNTILL i connect to the net which only then it will start to use 100% cpu usage where it use too use 100% cpu from boot up. So if anyone can further help me out plz do so. Kojak
