I have discovered than when I use either IE or GC my laptop suddenly freezes and I have to hold on the power off button for at least 5 seconds until I switch it off. This started happening after I formatted my laptop and I installed a fresh copy of Win 7 the Ultimate editions 32-bits. I have also noticed that even if I don't use any of the internet browsers and I leave it still few minutes later freezes unexpectedly. Has anyone ever experienced this before? Forgot to say that this is definately not an overheating issue.
