I noticed some people having some problems with P6 and XP, such as pointers disappearing. There's been quite a few comments regarding drivers and cards, but there are also some changes you change make inside XP. At the minimum, they may improve performance; at best they could improve reliability. 1) Right click on "My computer", and choose "Properties" 2) There are several tabs at the top. Choose "Advanced" 3) In the top section, you'll see "Performance. Visual Effects, ...". Press the top "Settings" button. 4) You're presented several radio buttons. Choose "Adjust for best performance." 5) Press "OK" and "OK" This disables most visual effects in Windows XP. A freebie from Microsoft called TweakUI, will disable some more under the "general" tab. It's part of the "Power Toys for XP" By the way, Nvidia has it's own control panel for some cards. It controls menu transparancy, among other things. Worth taking a look. Though it's not strictly related to video, if you're using the "Classic" Win98 interface on XP, disable the "Themes" service. You might consider disabling the "Indexing" services also, as it's quite a memory hog, and in my opinion not needed. Cheers
