Device manager/properties/driver/driver provider is what I listed. Most of them say Microsoft windows Hardware Compatabilty Publisher as Digital signer. I had a look on the Dell website so see what latest drivers were (mostly listed under Vista 64 bit), but I can't be sure if these newer drivers arrived in Windows Update or I fished them off the Intel/ATI website (which might not be so smart I guess).
My recommendation then, is make sure you get exactly what the chipset is for the devices in question. I wouldn't use the ones from the Windows Updates provided unless they were microsoft products, mostly cause I have actually seen a system get twitchy using those and I went to go get the drivers from the manufacturer's website and stabilized the system.
Read the documentation from the drivers you did get from Dell, that should help you get at least an idea of the drivers you should be looking for from the manufacturer. Also, do the drivers one at a time. No need to do all of them unless you want to, as your first priority is to identify what is causing your wife's system to freeze for a bit. From my own experience, it is best to try re-create the issue as much as possible, paying attention to what is happening at that time to help you identify the root causes of the issue. Like is the Hard Drive working hard, then that narrows it down to being the Main Board and/or Drive Controller drivers needing to be looked into. Was it something that was to make a sound, then focus more on the sound card. Was it something to do with video, look at the video drivers. Was it something net related... Network card drivers.
As always, be consistent when you test it. Otherwise, you won't know if you have addressed the issue and having a mad wife come at you with scissors.
