system interrupts

I've tracked a problem that only began since a recent clean install of the OS, in which the mouse cursor intermittently becomes erratic. When this does happen, the CPU becomes abnormally active, with spikes to about 30%, with the last 3 cores out of 6 going as high as 75-80%. The Performance...

I'm at a loss here. Have been working on this thing for days. I have finally installed all of the updated drivers of every component and device that is in this thing. It took forever because of the CPU lag. This happens right at start up so its very difficult to install anything on this thing...

I installed Win 7 and then went back and re-installed all of the drivers. I then went into the Device manager and updated the drivers via windows and the internet. Yet everytime I enable the connection to the internet my CPU usage jumps to 100% and 40-60 percent of that is because of the System...

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...

I have Window 7 64 bit running on a Gigabyte GeForce 8200 motherboard with a AMD 4850e CPU. From time to time the CPU usage jumps to 100% and stays there no matter how many processes and services I kill. Checking the Resource Monitor in Task Manager shows that System Interrupts is using the...

Hello! I have constant 8% CPU usage in Windows 7. It does not show up under any particular process in Task Manager. Resource Monitor says that it is System Interrupts. I suspect this is a driver issue -- is there a way to get more detail on what is sending interrupts to the CPU?

After leaving the PC idle for a few hours, the CPU usage increases to 20%. This is a very large increase from the CPU usage after starting up (and a few hour later while using the PC) were the usage is approximately 3%. Notes: CPU: Core I7 920 (2.8 quad core) Mother board: MSI X58 Platinum 3GB...

Processor is running at a consistant 90%. System is dual boot and runs fine with xp home. If I take out my graphics card (Radeon R4830) Win7 runs good. With the card installed, cpu runs excessive with around 90% going to system interrupts. Nothing showing in services. The attachment is a fresh...
