What Dave and CarmenElectra said. You either have a duff install of Acrobat, a PC in need of a good tidy up or a computer that is no longer powerful enough.
In addition to reinstalling, try the following, defrag your harddisk:
Click on Start > All Programs > Accessories > System Tools > Disk Defragmenter and click Defragment to start it.
If you have a lot of data and perhap a large HDD it will take hours so you may want to start it before you go to bed and leave it running overnight. You can save some time by rebooting into safe mode and then running it. You should be doing this at least once a month.
Another thing worth trying if this problem also occurs when you are trying to read pdfs whilst browsing the Web is to do the following:
Click on Start > Control Panel > Network and Internet Connections > Internet Options. Make sure you have the General tab selected then click on Delete Files... Place a check in the box next to Delete all offline content and click Ok. It's also worth going into Settings and adjusting the amount of space given over to temporary Internet files. Increase or decrease according to the size of your HDD and your own personal preference. If you're not sure, just post the details here and you'll be sure to get some good advice very quickly.
There are other things you can do to resolve the problem if it still persists after trying the things mentioned here on this thread. Acrobat is compatible with Windows XP so you will not have any problems in that regard, but you may find your computer needs a little more memory etc. to run all the things you like to use.
