Windows 7: CPU Usage 100%

CPU Usage 100%

Hi Everybody,

I installed Seven build 7000 yesterday, and I'm having problems with CPU usage being stuck on a 100% even when the system is IDLE. Does anyone have any suggestions on this issue?

Thanks,
Jonathan

i had the same thing happing but it was memory not cpu . i did a new clean install and memory went back down. did you install over a copy or clean install? if you installed over another copy that may be the trouble..

Hi, prjoni99, and welcome to the forums.

Did you perform an upgrade or a clean install? have you tried performing another install? My CPU utilization is near 0 at idle....

I performed a clean install. So far I have installed AVG free, Office 2007, Google Chrome, WinDVD 9. I have uninstalled AVG because I thought that was the problem. CPU Usage is still way high, I think I would have to blame Svchost for the resource hog. I have also disabled Windows Update and the aero interface and went to Windows Basic. Do you guys have any other advice?

Thanks,
Jonathan.

The problem with saying it is Svchost is that is just an executable wrapper that is used to blanket a Windows service so it can be called as an executable - and if you use a more robust tool like Process Explorer then you'll see that that one file (and usually there are like 2-4 instances of it running) can have a whole bevy of services that it is actually loading.

Windows XP/7
 
 

Hey everyone I am having this exact same problem. I have clean installs of both the 32 and 64 bit versions of 7 on my home machine, which runs XP really well. My specs are easily better than the minimums (2.2GHz Athlon 64, 2BG RAM, 1GB Video card.

Both installs are virtually unusable because the CPU usage is constantly pegged at 100%. I have installed nothing more than the driver for my graphics card. When there is nothing running, I will open up task manager and it will usually show 50% CPU being used by windows explorer, and 50% by tskmgr.exe. If I open up IE, it will split the three, 33/33/33. Sometimes it fluctuates, but basically all available CPU is always being used up by some combination of the running processes.

I am dumbfounded here. I thought my machine just couldn't hack the 64 bit, but the 32 bit version does the exact same thing. Any help or advice would be highly appreciated.

Did you see any updates on Windows Update regarding your chipset?

my resource monitor show CPU avgs 50%

just installed Windows 7 64 bit. only programs running are antivirus and firefox plus a bunch of windows related stuff necessary I guess to run the computer.

just watching the cpu monitor it stays right at 50% as it scrolls by with little bitty jumps now and then. would hate to see it if I was actually using any program that was demanding. guess I better look at this in vista 64 bit and see if its the same.

is there anyplace in windows help that explains what all that means in those meter boxes? network frequently jumps to 100% and disk to 100% as well.

to compare with vista 64 bit CPU usage....

just posted I had 50% CPU use with Windows 7 64bit and now checking stats in vista 64...

CPU usage is kicking around under 10% like 5% with no spikes near 10. actively running firefox, antivirus, comodo firewall, video drivers.

network use is much lower (don't really know what their score basis is)

have discovered the help there to explain what these things are tho.

shocking difference, from 5% in vista to 50% in Windows 7 unless these are not really comparable ratings.
