I have read articles online and also watched youtube videos. nothing has helped me, this is my last resort and hopefully someone will know how to fix my problem. a minute or two after I boot my computer my CPU usage sky rockets to 90-100% used. unfortunately this slows down anything I do and is a difficult obstacle to overcome when I have to write papers for school or play games on my free time.

tl:dr version: 100% CPU usage slowing comp down - svchost.exe = culprit wut 2 do?

A lot of thing can be listed as svchost.exe

Start Run “services.msc” no quotation marks.

Ctrl + Alt + Del and close the 100% svchost.exe and watch which one closes on the services.msc page. If absolutely nothing changes, then you've got a piece of spyware passing itself off as a Microsoft service, and you'll need to use generic troubleshooting to identify and remove it.

sometimes i have a bunch of those too but not all the time its weird, when i hit end process a a lil box with a timer of like 0:50 seconds is like ur computer is gonna shut off b/c of so and so forget havent had this problem in a long time

Yes, ending a service through the Task Manager can do some funky things like that.

Another alternative is just to open the Services thing like I described above and then if you see one running, Stop it and see if the CPU drops back down. If not, restart it.

Obviously you should avoid stopping services that sound critical, but I think the odds are pretty decent it's a virus in the OP's description and not actually a service.

This guy's right, stopping it in services is safer when isolating this issue.

It could also be that your computer just sucks

Agree'd with the above so far. After you delete the spyware process that is harming your computer(If this is the case) Run a virus scanner and find it. If you can't find anything the easiest option would be to System Restore to an earlier date when it did work.

Let us know what happens from here. 100%Physical memory dump can be annoying cause it makes everything snail speed. But run the steps above and you should be good. Post more info for more help!

If you use Task Manager to close a process and you get the shutdown timer, just type the following in the RUN dialouge box

Shutdown -a

That command tells windows to Abort the shutdown. Closing a process from Task manager will not harm anything, windows shutsdown when it thinks a critical application has closed (Which cannot happen from Task manager) - so it shutdowns to protect itself.

Also try running your Startup program list by typing MSCONFIG in your RUN dialouge box. This will open up your Configuration utility. Next click on the Startup TAB. This shows all the programs that load when windows starts. Uncheck everything you dont need (you actually dont need any of it, but your virus scan etc load here). After unchecking the useless junk (or all of it for that matter) Click apply, then close and you shoudl get a prompt to reboot. Reboot and see what your CPU use improvement is. If you wish you can reopen MSconfig and turn known items one one by one rebooting to make sure you dont turn on junk you dont need.

thanks. it ended up being a virus. i found the svc that was using up all the cpu, and when i tried clicking verify on the svc it said virus blocked or w/e norton says

thanks for all the help, really appreciate it

reinstall windows will fix it up 100%

This isn't always true. Some of the more insidious viruses can survive a reformat by hiding in the boot sector, then as soon as an internet connection is re-established, it immediately downloads itself all over again (even in the presence of antivirus software). This is one of the reasons why it's always important to make sure Windows PC is on its most recent service pack before connecting it to the internet (this is only really an issue if you reformatted as a last resort to remove a virus).
