Windows Forum / Windows Vista / Performance and Maintainance / May 2008CPU 50% System idle shows 98%
I have Vista Home premium for 2 years. About a week ago it slowed to a point where it may take 5 minutes to respond. Task manager Performance shows about 50% CPU usaage but Processes says 98% idle. If I start in safe mode Task Manager is the same but I seem to get a little better response. I use a free version of AVG. This problem seems to show up a lot in Google but each one seems to get resolved a different way. I tried some things others did but it has had no affect. The last time I started there were about 10 SVCHOST processes. I ended a few but nothing changed. It takes a long time for one to end because the response is so slow. And it gets slower the longer I am up. Where do I start to get to the bottom of this?  Signaturesmberger smberger;707217 Wrote: > I have Vista Home premium for 2 years.

Hi SMBerger, This tutorial may help you with increasing your performance. Try especially steps 1, 6, 8, 14, 24, 25, 26, and any other that your would like to do. http://www.vistax64.com/tutorials/81176-speed-up-performance-vista.html Hope this helps, Shawn SignatureBrink *There are no dumb questions, just the people that do not ask them.* '*VISTA FORUMS*' (http://www.vistax64.com) *Please post feedback to help others.* Thanks, I will try them this weekend when I get home and will let you know how it went. I have to do some work from home starting May 16 so if these things do not work I will be reloading Vista. Signaturesmberger I just read them and I have done at least half already based on info I googled. How do I *::Install the Latest BIOS and Device Drivers. ::* How do I know which I need. There probably is some info on it somewhere. Most performance enhancements will help in general but I would be surprised if they resolve my problem since I actually have something using the CPU. Signaturesmberger SMBerger, If you can give me the brand and model number of your motherboard, or model number of your OEM (store bought) computer, I can look up the information for you at their website. Shawn SignatureBrink *There are no dumb questions, just the people that do not ask them.* '*VISTA FORUMS*' (http://www.vistax64.com) *Please post feedback to help others.* Hi Shawn, I bought this desktop from Cyberpower. They replaced the motherboard in September '07 and it was different than the one I originally had. Now that I think of it, being that it is fairly new am I barking up the wrong tree? Signaturesmberger Just simply switch off the Superfetch function, this function is not suitable for old computer. > SMBerger, > [quoted text clipped - 3 lines] > > Shawn SMBerger, If it is still under warranty, then you might check into that option to see if they can look at it for you for free. You can download this free program called "CPU-Z" that will tell you what your "Mainboard" information is. I will need the Manufacturer and Model number under Motherboard to look it up. This program does not install on your computer. It comes in a ZIP file that you just extract all the files on your desktop and run the cpuz.exe file. 'CPUID' (http://www.cpuid.com/cpuz.php) Shawn SignatureBrink *There are no dumb questions, just the people that do not ask them.* '*VISTA FORUMS*' (http://www.vistax64.com) *Please post feedback to help others.* Hi Shawn, It has been a long weekend. Anyway, I decided to reload Vista. The PC came with a disc that was labeled Vista recovery. I called the company tech line and they told me it reloads Vista and I would lose my own files. Well, they were wrong. I started recovery and it looks like it connects to MS to do the recovery. It said it would take a few hours. It took a little over 11 hours. First it does some checking, then gets files then loads and keeps rebooting and eventually it gets done. It then tells me that windows will not activate without my typing in the Vista product number, which you would thing that would ask for before it started. Anyway when yhe desktop came up I had my own stuff still there. A citrix connection to work which did give me an error message but did connect me. And I still had Firefox and few other things. And response was OK but not great. But the kicker is that when I checked task manager it still shows 50% CPU usage. Maybe I just never noticed it. Does Vista use that much? The performance screen is split. The one on the right the graph shows it is all the way up and the one on the left just shows 1 or 2 percent. So in total it is around 50 -52%. But then why does processes show 98 percent idle. I am going to try the list you sent me to see if anything changes. It was impossible to try before because it could take 5 to 10 minutes per response. Thanks again and I will keep you posted. Signaturesmberger Do you have a dual core CPU? If yes then Idle is running 98% of the time and since it only requires 1 CPU your total CPU usage is 50%. > Hi Shawn, > It has been a long weekend. Anyway, I decided to reload Vista.

It will list everything that is using the CPU and by how much percentage. It may help in finding out what is using so much. What CPU do you have? If it's a older slower one, then Vista could put a bit of strain on it. 50-52% is still a lot though. This tutorial will show you how to open the Resoure Monitor if needed. http://www.vistax64.com/tutorials/111020-resource-monitor.html Hope this helps, Shawn SignatureBrink *There are no dumb questions, just the people that do not ask them.* '*VISTA FORUMS*' (http://www.vistax64.com) *Please post feedback to help others.* Hi guys & gals, There is another post in this forum "suddenly slow" which also describes this problem. I too am experiencing the problem. I am getting the feeling it is a windows vista problem probably from an update installed recently. somehow we need to get ms involved to resolve this issue. we can't all be using the same hardware or have the same program installed that would be common to cause this issue surely > SMBerger, > [quoted text clipped - 10 lines] > Hope this helps, > Shawn Well if you google vista cpu you will find lots of similar issues. I tried some of the things that helped others and it did nothing for me. In some instances people had just loaded something new but in many cases it turned out to be something in Vista. But the problem is how to find it so that you can shut it off. So I will try what Shawn suggests and see if I can pin it down at least for my PC. You should try it for yours as well and see what comes up. Signaturesmberger Hi Shawn. I got through a few steps from your list last night. What is-Click on *Continue *(UAC), *Yes*, and then *OK* when prompted.I never got that. So far no improvement and in fact it seems to be getting slower. If I move a panel it gets recreated over and over from the place I started till where I place it. I will continue on with the list tonight.

Unless you have UAC turned off or elevated the administrator account, it will usually pop-up after you click on the "Resource Monitor" button in Task Manager asking your permission to "Continue" before running it. Shawn SignatureBrink *There are no dumb questions, just the people that do not ask them.* '*VISTA FORUMS*' (http://www.vistax64.com) *Please post feedback to help others.* Your system may be getting hung up waiting for disk transfers. How much memory on your system? Do you have DMA disk transfers enabled? How much disk space do you have allocated to your paging file? > Hi Shawn.

Signaturesmberger Use Help for DMA or for Paging Paging is also known as virtual memory. SvcHost is the host task for your system services most of which never run after first being started unless they are needed. > JW;711831 Wrote: >> Your system may be getting hung up waiting for disk transfers. [quoted text clipped - 12 lines] >> I usually see many svchost processes. Does that mean anything. It >> usually does not show any cpu usage for them. SURPRISE My cpu usage is down to zero and I don't know why. Here is a clue. I caled the tech line where I bought this pc and he wanted to check the memory. I did not have time and told him I would call back later. Before I caled him I shut down the system and removed the back so I would have access to the motherboard. I called and the line was busy so I turned the PC back on and CPU usage was zero. What does that tel you. Is there a hardware problem waiting to happen again? Signaturesmberger SMBerger, I'm not sure why it would suddenly go back to normal for no apparent reason, but I'm glad that it is working normally for you now. To be safe, I would keep good backups just in case. Shawn SignatureBrink *There are no dumb questions, just the people that do not ask them.* '*VISTA FORUMS*' (http://www.vistax64.com) *Please post feedback to help others.* Hi Fello Forum Members, As previously listed I have the same problem. I have just concluded a call with MS tech support here in Oz and found that the Computer Associates CA AntiVirus software I am running may well have been the culprit. Apharently an update to that software clashes with an update from MS. The tech support people have "snoozed" CA to determin if this is the real problem. Will let you know how I go over the next day or so if you want. Good luck with your problems Regards RF > I have Vista Home premium for 2 years.
