Three days ago I installed Windows 7 Professional (32-bit) on my 2-yr-old machine (it was a clean install on a new drive, not an upgrade install). The installation went quite smoothly, then I installed all the 'important' windows updates, then a bunch of applications (VS2010, Skype, Chrome, GTalk, Steam), all of which were working fine for about a day, no performance problems to speak of, I also installed the latest ATI Catalyst video drivers, downloaded from ATI's website.
The following day I installed additional windows updates, including some of the 'optional' ones such as 'windows live essentials' and 'windows security essentials'. It is roughly since then that I have been noticing these problems:
- Chrome freezes when I start to load certain websites, such as gmail (about half-way through the loading bar)
- I installed Firefox, but it too locks up after seemingly random periods of time, but it recovers if you wait around 5 minutes.
- Skype froze whilst in the middle of a call, and also recovered after 3-4 minutes
- Installers for the Sun JDK, Python and a few other applications took an extremely long time to run
I checked for updates again and this time it told me about SP1 and a few more updates, which I tried to install, the installation was taking an extremely long time and failed the first time, on the second attempt they succeeded, but the problem has not been resolved, I am still getting intermittent freezes in several applications.
Any ideas what could be causing this, or if there's a known issue with a particular update that I should roll back? Thanks!
