Try DEFRAGGING! It's amazing what a defrag can do for your system. I try to defrag at least once a week if not more. My drives have lasted well over 2 years and I expect them to last longer. I did wait about a month since the last time I defragged and my drives were opening slow. I defragged and BAM! Now they open up lightning quick again.
If your system hangs about 2 or 3 minutes at startup, where you can't access the Start button or the Taskbar, it may be due to one specific service (Background Intelligent Transfer) running in the background. Microsoft put out a patch for this but
it didn't work for me. Here's what you do:
1. Click on Start/Run, type 'msconfig', then click 'OK'.
2. Go to the 'Services' tab, find the 'Background Intelligent Transfer' service, disable it, apply the changes & reboot.
Before you try that see if the 'workstation' is disabled. Normally you can get to it from the control panel but mine has disappeared so I used the start menu/administrative tools/computer management/sevices & applications/services. Scroll down to 'workstation' & see if it is disabled. (That's if you don't need it)
