I just did a fresh format and install of Windows 7 because of some issues I was having previously.
I formatted the drive, installed Windows and updated all my drivers and programs today.
Randomly now, the computer will 'hang' and be unresponsive for 3-15 seconds at a time. It seems multiple things cause the problem, sometimes it's loading a webpage, or opening a program, or navigating between folders in Explorer.
Prior to my format and reinstall I never had this type of issue before, and all the hardware aside from the DVD drive is the same, so I'm wondering if it's some sort of a Driver conflict, but I really don't know to tell.
I tried, but while it hangs it won't load any utility to let me check, and the hanging is usually not long enough to do it.
In the end I got frustrated and reformatted to try again. All was working perfectly for a day or so until today, after installing a batch of around 50 KB series Windows 7 Updates, at which point it came back. I just did a system restore, and thus far (30 minutes in) all is going well... though it's a bit soon to know for sure.
Googling a few of the updates, kb977074 looks suspicious.
I have disable any automatic updates and will be installing updates 3-5 at a time until I can isolate which one(s) are causing this awful hanging problem
