Vista freezes

Message: Two problems. Vista freezes & Upgrade disk (that came with the lap top) not working. When I am working w/Vista the program freezes. It freezes when I was fill out forums etc. I can click on a tab or click to highlight something in the form & then nothing happens until I switch screens to another windows tab & switch back , then the tab I clicked on is highlighted or filled out. When this happens I can't scroll down to continue to fill out forms w/out clicking back & forth from different windows that were opened. NOTE: I just went to click to send this mail & I clicked on the "Notify me on replies" tab @ the bottom & nothing until I clicked to another windows screen & then I clicked back & it was highlighted all on it's own. Go figure! I need help, I just purchased this lap top last week (HP Pavilion DV6000 ducore 32 bit, 1024 ram, 120 gig hd, Vista Home premuim) & I am tired of switching screens just to fill out something. Thank you, P.S. I tried to install the upgrade disk that came w/the lap top but it wouldn't install. (titledupgrade your windows Vista experience). The disk stated that during install the lap top might shut off & turn back on, well it did & I left the disk in the drive & when it rebooted the program wanted to start all over again. I tried it again but removed the disk & then it started the regular windows features.If the disk that came w/the lap top is a upgrade I have to pay for then I do not need it. I talked to the guy @ Circuit City (first mistake) & he said the upgrade disk (32bit) is just to upgrade the Vista windows to fix changes. I don't think so but...............?
