I work from my house and need several windows open at once and I have to reboot several times a day because it just freezes. I also have an HP desktop. I had similar problems with unexplained Windows Vista program freezes, lock-ups and similar frustrations running on my new as of September Dell XPS desktop. Some of these problems were software-related and eventually resolved with service packs, updates, etc. But the biggest help by far, which I've read very little about elsewhere, was when I bought and installed an uninterruptible power supply UPS for my PC and monitor.
For the record, I am using a watt CyperPower unit but I doubt the brand name is the important part. Turns out Windows Vista and at least this particular PC model are very sensitive to power fluctuations, many of which are invisible in terms of other electrical appliances in the home.
I often use the Windows Vista sleep feature, and I'm now convinced that power fluctuations can wreak havoc on what's stored in memory and will show up as intermittent problems when the computer awakes.
Of course the UPS also guards against outright power failures, which occur somewhat frequently in my neighborhood during summer and winter storms. When the air conditioner in our home kicks in, this, too, can sometimes subtly alter the AC power causing the UPS to briefly kick into gear.
I've never used or thought I needed a UPS in over 20 years of computing, but this was one of the single best computer purchases I've made this year. Notebooks have batteries, so a UPS is not required, and therefore power is not causing my lock ups and freezes in Vista. I have to close IE7 and sometimes restart in order to get my notebook running again. Naturally, I lose whatever I am working on, so this is very annoying. It reminds me of the days with Windows 95, 98, and Millenium.
I saw on another site that someone solved a similar problem of lock ups by changing their notebook's Power settings from Balanced to Performance. Mine was set to Balanced, but now its on Performance, so we'll see. It may take a week or two before I know if this really cures it. I had a lenovo laptop with 1gb ram and it was sloowwwww by default due to the crap they put on there.
