I installed Windows 7 in a 3 year old machine, it installed successfully, took all drivers and running great, but what happens is every 5-6 minutes it freezes for few seconds... 30 seconds to 1 minute and then comes back alive.
I checked Event Viewer, nothing matching the frozen timeline.
I would appriciate any help on how to detect causing service/hardware.
After it comes alive, everything runs normal, I did run task manager and checked cpu usage, at time it freezes just before and after that no task took more cpu or memory, it was like idle machine.
No external usb drives or no devices, on board intel desktop board with SATA HDD, SATA hdd running in absolute good mode.
