When you're at the Task Manager interface, make sure to click the "Show processes from all user", so you can see all the processes running. Is this your first time using 64-bit? Apparently there are CPUs that are not compatible with 64-bit. Though, I'm just throwing this fact out there ... I have no idea whether your CPU is or not.
I have had Vista 64-bit without any problems. I tried the "processes from all users" and noticed that svchost.exe is using quite alot of memory at 126 kB, but the CPU seems somewhat stable now at 1 to 10%. I tried that the first time and after running stable for a while it went up to 95% just like that.
What about at save mode? Still high usage? A friend of mine had the same issue. At Vista 64 bit was all fine, at W7 64 bit the CPU usage raised randomly to 100%. It was a driver of his (old) sound card...after uninstalling the driver (card) it was fine...
Right now I'm in safe mode and it seems to be alright. It's fluctuating between 0% and 10%, I suppose thats good? The problem is that it went up to 100% on random times even after days have passed. I checked all my drivers and they were up to date. Gentoo, I tried Windows Performance Toolkit from Windows 7 SDK but I couldnt get it to work.
Ehm I dont remember the error I got, but I just re-installed it and I see 2 new tabs in my program list "Microsoft Windows SDK v7.0" and "Microsoft Windows Performance toolkit". Do I have to run the Performance Analyser or CMD Shell? Those are the only 2 programms I see.
wow i went thru that problem before and with the use of safe mode i was able to determine a problem with one of my drivers within Nvidia mobo (while using vista 64) it was so bad that it will freeze everything, so i know how you feel. Truly confusing how even with safe mode on your end still goes thru the issue. Im out of ideas since all other were already said. I do recommend as other has said, just unistall one driver at a time, i bet is one of your hardware driver, which one, well u will need to find out.
Yeah it is frustrating, it makes me want to re-install Vista again. Can I just uninstall every hardware driver without busting something? Maybe a dumb question but I dont know THAT much about computers.
yea first of all search for all your new drivers, download them on place them on a folder within your desktop, and i mean all drivers, ethernet, video card, sound card, any driver you might have. Also update your bios if is not moddified. Once you have search for all drivers, and if you need help check your device manager so you know which hardware you have. Then i recommend using safe mode to unistall them all, restart your computer in safe mode and reinstall your harddrive, i hope that can help you
This problem is caused by one of your usb devices wich causes on a high cpu usage why that's still not discoverd. If you see that on usb device is not working after this problem and you dont need it very much disable it in devicemaneger. Or disable all usb and there is a big chance that you don't get the problem.
In that case, it'll probably be your CHIPSET drivers or USB2.0 drivers (the latter being unlikely though). But disabling all usb will not solve the issue, nearly bypass it. So try to identify which driver causes this. Uninstall every driver you may have in safe-mode, and then re-install one by one, beginning with your vendor's chipset drivers. These NEED to be installed FIRST. Then try it out, see if the issue is still there. Then install the next, and check it out again. If all are installed and the issue is still present, then it's probably not a driver issue at all.
