My task manager is indicating CPU Time at increments of about 4 times, that is 4 seconds every 1 second, what is wrong and how may I fix it. Any suggestions welcome.

Hi Marcus. There is already a recent thread related to this situation. Click here to learn more.

No, maybe I did not explain myself properly. When I press CtrlAltdelete naturally windows taskmanager comes up. Now in the "Processes" window the time is running at about two to four times the normal speed.

My apologizes. However, when I did the same thing you did, I do not see any indication of time in the Processes tab of the Task Manager.I am looking directly at my Processes tab, with the screen maximized, and this is what I see:- All of the current Processes (63)Columns - Image Name, User Name, CPU, Mem Usage- There is a check inside the box next to "Show Processes from All Users"- The "End Process" button is on the lower right side- In the status section, I see:Total number of Processes - 63CPU Usage - 3% Current Charge - 598M/3940MCan you please clarify exactly to what you refer when you mention "time?" Also, what Operation System are you using?

Try the View menu in the Windoze Task Manager. There should be an option to change the Update Speed between High, Normal, Low, and Paused.Does that help with what you are talking about? I am in agreement with MPH...it is not clear to me what you are specifically talking about.

Ok, in the processes menu click on "view" in the toolbar and then on "select columns", a box should come up and tick in the box next to cpu time. Now one of the columns should, I believe, indicate the accumulated time that the CPU has spent on each process. When when System Idle process is close to 100% "CPU Times" accrues at approximately 2-3secs every sec. now I know from past experience that this should be on a strictly 1:1 ratio, changing the update speed has no effect. Incidentally the clock in the taskbar is running perfectly. Thanks

Hi Marcus. So is your problem more related to high CPU usage? I personally have never usage CPU Time as a reference. That being said, I have some more questions:- How often does your CPU usage reach around 100%?- What processes or applications bring the usage to 100%?- When was the last time you ran Error Checker and Defragmented your hard drive(s)?

When I first looked at it, the update speed was set to "Normal" and I thought that it was doing like your said (the accurred System Idle Process APPEARED to be jumping about 2 to 3 seconds for every second). But, if I put an actual clock that showed seconds right next to it, then it was clear that it was just a matter of the update was showing the 2 to 3 second increase, but the update was NOT occurring each second...it just seemed that way when I had no "true" point of refence. If I put the update speed to high, then it clearly changed 1:1 when compared with a point of reference (i.e. a clock with seconds being counted).

No, the discrepency is real, what you are seeing is because the default update interval is 2 sec.

Marcus, at the time of this post, this thread has been read 130 times. Of those 130 views, I hoenstly do not think any of us know exactly what you are asking. The bigger question may be what you are NOT asking."Why does your computer approach 100% regularly enough for you to have to monitor your system?"I listed several troubleshooting questions in my previous post. The CPU Time not being "in tune" with what you feel it should be is not a cause, it's an effect. The "cause" is your system CPU usage spiking as it does.Please answer the questions I listed previously and we can try to figure this out together.

Sorry for the delay in answering Mphenterprises. My CPU usage does not regularly reach 100%. It is normal in all computers for "System Idle Process" to be high however. I do not feel that my CPU usage is spiking, in fact I have no complaints at all on that matter. I was doing some research elsewhere and found similar cases where other persons were reporting that their CPU time usage is running at double speed. In all cases this occurred with dual core CPU's, and that apparently what is measured is "processing time" and not "real time" I am only surprised/confused that I never noticed it before!

Hi Marcus. Okay, if you are not concerned about CPU uage, I am still confused by this thread. I have a dual core processor and I also do not see any significant spike in usage unless something is supposed to spike it.I know that System Idle Process should be high. In fact, basic calculations state that the CPU Usage has to total 100%. If all of the processes that are running within a specific computer total 10%, then the SIP will logically have to be 90%However, unless you have noticed something specific within your computer to bring this situation to light, I think you are making more out of this than necessary. If you computer performs as you feel it should and if you are satisfied with the overall performance of your computer, why look for something that is not there?Again, I may be missing your point but I am only going by the information you have provided.

There is a CPU Time column that is typically turned off by default. If you go to the View menu and select the Select Columns... item, then a dialog box opens that allows you to turn on and off specific columns of information. The one that he is refering to is CPU Time. My guess is that you don't have it turn on. That column shows a running time total of CPU time useage.I was starting to suspect that it was a dual core issue. Makes sense...with a dual core, you technical have the equivalent of two CPUs.

Nope, I do have it turned on. I turned it on the same day that I realized he was talking about the Task Manager.When I did select it, I noticed that my Zune device (I was sync'n at the time) was at about two hours. I still do not think there is an issue unless he is not telling us something. What drew him to actually look at that column? Was it just curiousity? If the system is fine, why draw concern to a column that may be informational untl there is a problem?Again, I may be missing his point but I do not see a reason for concern until he comes back and says otherwise...

Actually, there never really was an issue, but rather a lack of understanding. I think he got his answer. His concern was that CPU Time was accurring faster than he thought it should (i.e. 2x faster). Turns out that due to a dual core procosser (essentially 2 CPUs), the time accurred at 2x. So, I think he has his answer.

Actually you see, I never noticed before, and I could swear the time was originally passing at 1x. However since my desktop is working normally I guess I may as forget the issue.

Not totally sure but I think I have the same problem. I believe he was saying his clock on the system idle process is running double+ speed. To clarify: If I shutdown my pc (2 year old dell dimension with Windows Media Edition) then start it up, if I go into the task manager an hour later, it shows the PC has been on for TWO hours, not ONE. I have checked other pc and none show this happening. I couldn't tell you if I have a "dual processor" but I don't think it matters. This is basically the "system UP time", why would it be doubling?
