I just did a clean install of Windows 7 Enterprise, 64-bit. The hardware is an ASUS P5Q-EM motherboard, Core i7 2.8Ghz quad-core processor and 8GB of memory.
After the computer is on for 30 to 60 minutes, it becauses extremely non-responsive. It basically seems to hang for three to five minutes, then it will work for 30 to 60 seconds. Then repeat itself.
I have installed the motherboard device drivers, SP 1 and all the updates from Windows Update. Windows Security Essentials is also installed.
I have also installed an application Core Temp that monitors the CPU temperatures, in case that was the issue. (The CPU cores are running between 45 and 60 degrees Centigrade.)
I also installed the gadget "All CPU Meter" to check on CPU usage. It appears that when the computer is freezing, one of the cores is running 100%. I have not installed any 3rd-party applications yet.
I'm not seening anything in the various event logs.
Anyone have any suggestions as to what I can check, or possible solution?

1. Try to pinpoint the process that make you troubles. Ideal tool for analysis is Process Explorer. You can get deeper and find the high load in processes/threads
What is the memory "consumption"? Another cause of problem may be memory leak - steady increase of memory consumption up to upper limit.
2. Whenever I install vanilla plain operating system, I install chipset driver first, then graphics, audio and network driver.
3. CPU temperature is relatively high though not critical, unless the limit is set in BIOS. I would recommend better cooler

Thanks for replying.
I tried running Process Explorer as you suggested. It's not showing anything new. When the system freezes, Process Explorer is showing System Idle at 71%, System 25%, ProcExp64 1.68% and couple other processess at less than 1% each.
Process Explorer is reporting memory consumption at about 16%. What I'm doing is booting Windows, logging in, start up Processor Explorer and then letting the system sit for a while. Then I click on the Start menu and run Notepad. Sometimes the system will freeze for a moment when click on the Start menu. I usually see the freezing when I try typing some text in Notepad.
I installed the device drivers in the sequence of chipset driver, audio, network and then graphics. I believe that Windows Update also updated the audio, network and graphics drivers.

Thanks for the reply. I was able to track down the problem to a device driver. Rolling back to a previous version has appeared to have solve the issue.
