60% CPU usage at idle After two days of no problems, the problem has returned. Task Manager processes shows the usual "System idle". And the only Event Record is an error: Event filter with query "SELECT*FROM_InstanceModificationEvent WITHIN 60 WHERE TargetInstance ISA "Win32_Processor" AND...

Yes indeedy, I have spent hours staring at System Idle using 97 to 99% of my CPU usage and when I look at services System Interrupts is the biggy. That has been typical for at least a couple of the people in the forum with similar problems. My only advantage is my quad core CPU allows me to...

Sudden change in problem My fix (leave scanner unconnected) suddenly quit working. After 2 days of no problems, suddenly a ~30% CPU usage at idle appeared. Later after restart, the old familiar ~60% usage appeared. Then again on a later use. Last, the dreaded blue screen data dump. The...

CPU Usage Windows 7 Latest Data All evidence at present makes me suspect my USB scanner as at least a big part of my problem. When it is connected, problem will eventually show up. When it is not connected, the problem is not now occuring. The hedging is because at one time in the past, the...

CPU Usage of Windows 7 Nimble, if you are real lucky the problem you are having is there from start every time. If so, look at Run Selective Startup using System Configuration which describes a method to track down the culprit(s).

CPU usage with Windows 7 My problem start the day, hour and minute I upgraded from Vista Home Premium 64bit to Windows 7 Home Premium 64bit. I have not removed Windows 7 and returned to Vista - but, I believe others in these threads have and the problem went away. My Machine is a new in May...

CPU usage problem with Windows 7 Wow, at least my quad core is "only" saturating at about 60% during my episodes. I am now in a microsoft support chat trying to determine a cause. It obviously isn't easy to isolate a cause (I've spent over 5 hours in the chat sessions so far). Updating...

Question + Do I understand that your problems were after you upgraded to Windows 7 32 Bit? I thought we had the same problem, but I have been using 64bit all along and am still having the system interrupts/cpu problem after numerous driver updates.

High cpu usage Yeah, I've got the same problem (randomly about 60% of my quad core is locked up) - and when I look at processes it tells me that system idle is 95-99 with taskmg & iexplore the remainder. Under cpu processes it shows system interrupts as the culprit. As a clue perhaps when the...

Problem Intermittent Rebooted, problem gone. Entered COD4 game - exited 4 seconds later problem is back, also USB devices dead. Task manager processes shows System Idle at 97 to 99 of CPU with remainder task manager and Iexplore.:confused:

Here is another poor soul sucked into windows 7, only to find that most of the time 60% of my AMD Phenom II X4 940 is tied up by what the resouce monitor claims is system interrupts. I have not added or changed anything since installing the windows 7 X64 upgrade to my Vista 64 system. I did have...
