I have a several-year old HP a6600f running Vista Home. It's a mess - esp WRT MS apps; and defragging etc don't help.
Problems include: applications (primarily MS apps, esp Internet Explorer, Excel 2007, Windows Explorer, and Media Player crash hard and often, either requiring repeated restarts of the program or freezing the computer. These often crash as soon as they are started. Other crazy issues with restarting, like I'll start a restart, go to bed and it still hasn't shut down by morning. I have antivirus sofware (Norton 360) scanning regularly so it would seem a virus is not the problem. Even more issues with installations, for example Windows Update.
The computer is a tool for me and this ain't a hobby, so I'm looking for a solution that works as opposed to takes a lot of my time. I have a work laptop, so this hasn't been a priority, but I need to do my bills!
As I see it my options are:
1) Try one of those registry fix things
2) Install Windows 7
3) Bite the bullet and buy a new freaking computer.
